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.
