Laminating Adhesives and Composite Resins Specifications

Help with Laminating Adhesives and Composite Resins specifications:

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.
	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.
	Other		Other unlisted, specialty, or proprietary substrates.

Chemical / Polymer System Type

	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.
	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.
	Phenolics / Formaldehyde Resins		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.
	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.
	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.
	Specialty / Other		Other specialty, proprietary, or unlisted resins, chemical systems or compound or polymer 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.
	Filled / Reinforced?		Filled compounds consist of adhesives with additional modifiers such as pigments or chopped fiber reinforcements. Typically, filled compounds are ready-to-use.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	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.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Solvent Based (Volatile Organic)?		Solvent-based adhesive resins use a volatile organic solvent (VOC) to thin or alter viscosity. Typically, solvent-based adhesive resins result in greater environmental or regulatory control problems. Solvents can also present a fire hazard or a risk of explosion, depending on the plant or job site.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Water Based / Latex Dispersion?		Water-based or water-borne adhesive resins are water soluble or water emulsion-based resin systems that typically do not contain any VOC solvents. Water-based adhesive resins usually present fewer environmental or regulatory control problems.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
