Substrate / Material Compatibility

	Your choices are...
	Ceramic / Glass		Ceramics consist of oxides, carbides, nitrides, and other non-metals with high melting points. Ceramics are suitable for applications requiring wear resistance, thermal stability, and electrical resistivity.
	Concrete / Masonry		Concrete and cements consist of a mixture of a binder or clinker and a coarser aggregate. They are used to patch or line floors and walls, bond brick, and join components for use in high-temperature applications. Clinker is a fused mineral or mineral mixture, such as alumina, bauxite, or lime, which is crushed into a fine powder. Aggregates are coarser, granular materials that are added to mortar, grout, or cement at mixing time to impart special properties such as thermal stability, wear resistance and oxidation resistance. Synthetic aggregates are fused mineral or mineral mixtures crushed to a coarse, granular size range rather than a fine, powdered clinker. Portland cement is the most common bond used in structural concretes and mortars. Polymer cements have a resin bond and are used in corrosion protection, mortars for corrosion-resistant floor tiles, and other specialized industrial applications. Masonry consists of tile, bricks, stone, or other ceramic components that are bonded together with mortar or adhesive.
	Composites		Composite materials consist of a resin (suitable for molding) and a matrix (typically fibers or textile material) which serves to enhance strength, alter electrical or magnetic properties, or enhance wear resistance.
	Metal		Metals are opaque, fusible, ductile, and typically lustrous substances that are good conductors of heat and electricity. They form cations by the loss of electrons and yield basic oxides and hydroxides. Metals that are used in structural engineering applications have a high toughness that is a combination of high strength and ductility.
	Paper / Paperboard		Paper or paperboard products are produced from a pulp of cellulose, cotton, wood, or other vegetable fibers. The pulp is laid down on a fine screen from a water suspension to form sheets that are dried and further processed.
	Plastic		Plastics are organic, synthetic, or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight. They can be made into objects, films, or filaments.
	Porous Surfaces		Substances are adhesives or sealants with a high viscosity or gel-like consistency. Typically, these materials have the ability to work with porous surfaces.
	Rubber / Elastomer		Rubber and elastomers are characterized by a high degree of flexibility and elasticity (high reversible elongation). Natural or synthetic rubber is vulcanized to increase useful properties such as toughness and resistance to wear for use in tires, electrical insulation, and waterproof materials.  Vulcanization is a chemical treatment that adds sulfur and heat to crosslink the rubber. Natural rubber is an elastic substance that is obtained by coagulating the milky juice of any of various tropical plants. Essentially, natural rubber is a polymer of isoprene, and is prepared as sheets and then dried.  Synthetic rubbers or elastomers can be based on a variety of systems such as silicone, polyurethane or neoprene.
	Textiles / Fabrics		Substances are adhesives or sealants suitable for coating, filling, sizing, or sealing non-woven or woven textiles. Sizing adhesives or resins are used to fill paper, textile webs, and other fibrous products.
	Wood / Wood Product		Wood is a natural composite extracted from the stems, branches, and roots of trees. It is a hard, fibrous substance that consists of xylem, cellulose fibers in an amorphous, lignin polymer matrix. Lignin is a biogenetic cross linked polymer which bonds together adjacent cell walls into a straw or wood tissue composite. Cellulose is a polysaccharide (C6H10O5)x of glucose units that constitutes the chief part of the cell walls of plants. It occurs naturally in fibrous products such as cotton and kapok, and is the raw material of many manufactured goods as paper, rayon, and cellophane.

Material System

	Chemical / Polymer System Type
	Your choices are...
	Acrylic / Polyacrylate		Acrylics feature excellent environmental resistance and fast-setting times. Acrylic polymers are produced from acrylic acids via a catalytic reaction.
	Bitumen / Coal Tar		Bituminous adhesives are used in roofing and construction applications because of their water resistance and low cost. Bituminous substances are hydrocarbons that occur naturally as tar, or are derived as by-products from petroleum or coal refining. Coal tar is derived from the distillation of bituminous coal.
	Ceramic / Inorganic Cement		Compounds or material systems are based on ceramic or inorganic cement systems.
	Cyanoacrylate		Cyanoacrylates are one-part acrylate adhesives that cure instantly on-contact with mated surfaces through a reaction with surface moisture. Cyanoacrylates are often called super-glues. They have high strength and provide excellent adhesion to a wide variety of substrates, especially plastics. Potential disadvantages include poor shock or impact resistance (brittleness), and poor gap-filling abilities. Cyanoacrylates that are modified with rubber or elastomers have overcome some of these problems.
	Epoxy (EP)		Epoxy resins (EP) exhibit high strength and low shrinkage during curing. Epoxies are known for their toughness and resistance to chemical and environmental damage. Most epoxies are two-part resins cured at room temperature. Some thermally cured or thermoset one-part epoxies are also available. Depending on the formulation, epoxy resins are used as casting resins, potting agents, resin binders or laminating resins in fiberglass or composite construction. They are also used as encapsulates, electrical conductors in microelectronic packaging, and adhesives in structural bonding applications.
	Glue / Gum		Animal glues include hide glues, casein or milk protein glues, and fish-based glues. Hide glues are produced by hydrolysis or by boiling collagen, protein, or gelatin from animal bones, hide, hooves, or horns. Collagen, hide glue, and gelatin are very closely related in terms of protein and chemical composition. Casein-based adhesives (carpenter's glues) are derived from milk. Vegetable glues are made from plant-based proteins or modified starches. Soy protein glues are finding increased application.  Gum adhesives or mucilage are based on polysaccharides derived from various plant exudates such as an oleoresin or gum resin. Gum adhesives are gelatinous when moist and harden after drying. Gum adhesives are the salts of complex organic acids.  Mucilage contains proteins and polysaccharides and is similar to vegetable plant-gum adhesives. Mucilage is a gelatinous substance extracted from legumes and seaweeds.
	Phenolics / Formaldehyde Resins (Melamine, Furan, etc.)		Phenolic and formaldehyde resins are thermosetting molding compounds and adhesives that provide strong bonds and good resistance to high temperatures. Phenolic or phenol formaldehyde, urea formaldehyde, furan, and melamine resins are all part of this category. Generally, the most durable phenolic resin adhesives are made from chemicals of the phenol group and formaldehyde. Phenolic resins come in liquid, powder, and film form. Special phenolic resins are available that harden at moderate temperatures when mixed with suitable accelerators. Phenol-formaldehyde, resorcinol-formaldehyde, resol, and novalac resins are types of phenolic resins. Urea resin adhesives are made from urea, formaldehyde, and catalysts or hardeners. Urea formaldehyde resins can harden rapidly at moderate temperatures, but generally do not have the properties of phenolic resins. Melamine resins are made through a reaction of dicyandiamide with formaldehyde. Most of the resins in this group have excellent dielectric properties.  Furan formaldehyde (FF) resins are made by the polymerization or poly-condensation of furfural, furfural alcohol, or other compounds containing a furan ring, or by the reaction of these furan compounds with other compounds (not over 50%). Fire-retardant furans are used in hand lay-up, spray-up, and filament winding operations. Furans are commonly used in foundry binders, grinding wheels, refractories, and other high-temperature applications. Furan resins and chemicals are also used in fiberglass composites, hybrid resins combined with epoxy or phenolics, and in corrosion-resistant cements.
	Polyamide		Polyamides are used to produce strong hot-melt adhesives with higher strength than either polyethylene or other hot-melt adhesives. Nylon is a well-known example of a polyamide engineering resin that is also used to mold plastic parts.
	Polyethylene (PE)		Polyethylene (PE) is used as a hot-melt adhesive.
	Polyester (PET)		Polyester (PET) is used as a hot-melt adhesive.
	Polyester / Vinyl Ester		Thermosetting resins or plastics are based on the polyester (alkyd) or vinyl ester system. These materials should not be confused with thermoplastic polyesters or PET resins.
	Polypropylene (PP)		Polypropylene (PP) is commonly used in hot-melt adhesive systems. PP is a polymer based on polypropylene chemical bonds.
	Polysulfide		Polymer resins or compounds are based on polysulfide or polyphenylene sulfide (PPS) chemical systems.
	Polyurethane (PU, PUR)		Polyurethane (PUR) resins provide excellent flexibility, impact resistance, and durability. Polyurethanes are formed through the reaction of an isocyanate component with polyols or other active hydroxyl group compounds. PUR resins require a catalyst, heat, or air evaporation to initiate and complete curing.
	Silicone		Plastic compounds, elastomer resins, or polymers are based on the silicone chemical system. Silicones are produced through the hydrolysis and polymerization of silanes and siloxanes.
	Starch		Starches and starch pastes are derived from flours or vegetable matter. Starches are useful additive materials for thickening and other functions. Pastes are commonly applied in light-duty adhesive applications on paper products such as envelopes, stamps, labels, or paper packing tapes. Starch-based pastes are low cost, non-toxic, and water-activated. In their dry state, water-activated adhesives are not sticky, but upon wetting become adhesive.
	Vinyl (PVC)		Polymers are based on the vinyl chemical system. Examples include polyvinyl chloride (PVC), polyvinylidene chloride (PVDF), polyvinyl vinyl acetate (PVA), and polyvinyl alcohol (PVOH).
	Wax Based		Sealants or binders are based on a wax compound. Wax binders are commonly used to bind ceramic or metal powder during compaction processes because wax binders lubricate and burn-off thoroughly. The original hot-melt compounds were based on paraffin waxes.
	Rubber Based / Elastomeric		Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). Natural rubber, synthetic rubber, or elastomer sealants and adhesives can be based on a variety of systems such silicone, polyurethane, chloroprene, butyl, polybutadiene, isoprene, or neoprene.
	Specialty / Other		Other specialty, proprietary, or unlisted resins, chemical systems or compound or polymer types.
