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.
	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.
	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.

Cure Type / Technology


	Cure Type / Technology
	Your choices are...
	Anaerobic		Anaerobic adhesives cure in the absence of air or oxygen.
	Thermosetting / Crosslinking		Thermoset plastics and thermoset resins are crosslinked polymeric resins that are cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat than thermoplastics, but cannot be melted down and reprocessed. Thermoset adhesives are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins do not melt and flow when heated, but they may soften. Phenolic, melamine, and urea formaldehyde resins are thermosetting adhesives that offer strong bonds and good resistance to high temperatures. Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials. RTV silicone rubbers are room temperature vulcanizing materials. The vulcanizing agent is a crosslinking compound or catalyst. Sulfur is the traditional vulcanizing agent used with natural rubber. Silicones use moisture, acetic acid and other compounds as curing agents.
	Room Temperature Curing		Room temperature curing or vulcanizing products are polymer resins or compounds that either cure or vulcanize at room temperature. Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent. It results in greatly increased strength, stability, and elasticity in rubber-like materials. The vulcanizing agent is a crosslinking compound or catalyst. Silicones use moisture, acetic acid, and other compounds as curing or vulcanizing agents.
	Reactive / Moisture Cured		Reactive resins are single-component adhesives that are applied in the same way as hot-melt adhesives. The resins react with moisture to crosslink and polymerize, thus resulting in a cured material. Polyurethane reactives (PUR) are examples of this type of technology. Certain silicones and cyanoacrylates also use a reaction with moisture or water to cure the adhesive or sealant.
	Thermoplastic / Hot Melt		Thermoplastics can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be injection-molded or thermoformed and scrap to be reprocessed. Thermoplastic or hot melt adhesives can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be removed or repositioned during assembly. Most hot melt adhesives are solvent-free thermoplastics that melt or drop in viscosity above 180°F, and then rapidly set upon cooling. They are used in a variety of manufacturing processes, including bookbinding, woodworking, construction, product assembly, and box and carton heat sealing. Hot melt adhesive technology stemmed from the previous use of molten wax for bonding. Thermoplastic systems were introduced to satisfy performance needs. Typically, a pure hot melt system will not have the heat resistance of two-part, catalyst, or thermoset adhesives. Hybrid hot melt systems are available that exhibit a degree of reactive curing. Polyethylenes, polyamides and ethylene-vinyl acetates are common types of hot melt adhesives. Heat activated adhesives become sticky or tacky when warmed, and are used in contact or PSA-type applications.
	Two Component System		Two or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator, or catalyst that, when combined, react and cure into a polymerized compound or bond. Two component systems are mixed and then applied.
	Single Component System		Single component adhesives or sealant systems consist of one resin that hardens by reaction with surface moisture, a surface applied activator-primer, or through the application of heat.
	Specialty / Other		Other unlisted, specialty, proprietary technologies or cure types.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Chemical / Polymer System Type


	Chemical / Polymer System Type
	Your choices are...
	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.
	Acrylic / Polyacrylate		Acrylics feature excellent environmental resistance and fast-setting times. Acrylic polymers are produced from acrylic acids via a catalytic reaction.
	Polysulfide		Polymer resins or compounds are based on polysulfide or polyphenylene sulfide (PPS) chemical systems.
	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.
	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.
	Vinyl		Polymers are based on the vinyl chemical system. Examples include polyvinyl chloride (PVC), polyvinylidene chloride (PVDF), polyvinyl vinyl acetate (PVA), and polyvinyl alcohol (PVOH).
	Specialty / Other		Other specialty, proprietary, or unlisted resins, chemical systems or compound or polymer types.
