Dura Pro™ Water-Based PVA and VAE Adhesives Homopolymer (PVA) & Co-Polymer Emulsions (PVA, EVA, VAE) Homo-polymers are the most commonly used technology on the market due to their excellent adhesion to a wide variety of "polar" substrates, particularly cellulosic-based substrates such as paper and wood. Dura Pro™ polymers are hard and brittle with high molecular weight, high tensile strength, rapid setting speed and are extremely cost effective. Dura Pro™ vinyl acetate copolymer emulsions can bond more difficult substrates such as plastic films, coated papers, and metal surfaces. Vinyl acetate copolymer emulsions are internally flexibilized with ethylene (VAE) or acrylate (VAA). The increased polymer flexibility provides for greater polymer mobility and better adhesion.

Dura Pro™ EVA Hot Melt Adhesives

Ethylene Vinyl Acetate (EVA) Hot Melts

Dura Pro™ EVA based adhesives that can be formulated for a wide variety of applications. The type and amount of wax and resin used with the EVA copolymer control set time and residual tack of the adhesive. EVA adhesives are used in case and carton seal, bookbinding, furniture assembly, general packaging, door assembly/millwork, appliance assembly, multi-wall and specialty bags construction.

Dura Pro™ PSA Hot Melt Adhesives Pressure Sensitive (Block Copolymer) Hot Melt Adhesives Dura Pro™ PSA hot melt adhesives (also known as styrene copolymer adhesives and rubber based adhesives) have excellent flexibility at low temperatures and high heat resistance. Although these products are primarily used for pressure sensitive applications where substrates are bonded after the adhesive cools they can be used in applications where bonding occurs while the adhesive is still hot. PSA adhesives are used in bookbinding, diapers, furniture manufacturing, case and carton seal, general packaging, doors/millwork, and appliance assembly.

Dura Pro™ APO Hot Melts (Amorphous Poly-alpha-olefin) Amorphous Poly-Alpha-Olefins (APAO) Hot Melts Dura Pro™ APAOs are used when an application requires good heat, acid or fuel resistance at an affordable price. APAOs are non-crystalline adhesives are that remain soft, tacky, and flexible giving longer open times and good adhesion. APAOs are used in appliances, diapers, furniture manufacturing, case and carton seal, general packaging, doors/millwork, and adult incontinence and feminine hygiene products.

Dura Pro™ Polyurethane Dispersion Polyurethane Dispersions (PUDs) Dura Pro™ Polyurethane Dispersions (PUDs) are polymers derived from isocyanate reactions. The adhesives are polymerized in water to produce a thermoplastic polyurethane emulsion which is thermoplastic and cross-linkable when reactivated with heat. Dura Pro™ PUDs have excellent resistance to weathering, plasticizers and solvents. Dura Pro™ (PUDs) can be used in similar applications as solvent-based polyurethanes including cabinet doors, furniture, packaging, paint formulations, plastic to glass bonding in the automotive industry, textile-cloth fibers, foam backed carpets, etc.

Dura Pro™ Emulsion Polymer Isocyanate (EPI)

Emulsion Polymer Isocyanate (EPI)

Dura Pro™ EPIs are two-component adhesives based on reaction of a mixture of water based emulsions of SBR, EVA and PVAc type with an isocyanate hardener (cross-linker) forming water-resistant bonds. EPI adhesives can be formulated in many ways to give the optimal performance with respect to water resistance, curing speed, type of substrate, strength and viscosity in each bonding operation.

Dura Pur™ Polyurethane Adhesives (Liquid and Hot Melt) One-part Polyurethane (PUR) Hot Melts & Liquids (LMC) Dura Pur™ hot melt adhesives combine the speed of hot melts with the strength of structural thermosetting adhesives. PUR hot melts are applied like traditional hot melts (applied while hot and set as they cool), have superior initial handling strength and are VOC solvent free. These adhesives are cured by a reaction with water. In most cases, sufficient moisture already exists in the air or in the materials being bonded but some environments require the addition of moisture through humidification systems to aid curing. Our Dura Pur™ adhesives form semi-structural bonds to a variety of substrates, including non-porous materials. They produce extremely durable, highly elastic bonds that perform well in extreme temperatures. Dura Pur™ one-part Liquid Moisture Cure adhesives form permanent bonds by a chemical reaction with moisture from the substrate or environment. These products are liquid at room temperature so bonded parts need to be pressed during the curing process. Dura PurT form structural bonds on a variety of substrates, including non-porous materials and are especially good for wood-to-wood bonding. They produce extremely durable, highly elastic bonds that perform well in temperature extremes. Two-Part Polyurethane Dura Pur™ two-part polyurethane adhesives are used for structural bonding of plastics, fabrics, wood and metals. Two-part polyurethanes are packaged in two containers (an A part or polyol and a B part or isocyanate) that are mixed before they are applied either mechanically or by hand. The combining of the two chemicals starts the chemical reaction that cross-links the adhesive. Dura Pur™ products can be applied at room temperature and do not need heat or moisture to cure. Handling strength and cure rates can range from a few seconds to 12 hours depending on the adhesive and environmental conditions.
