Products in Textile & Footwear Adhesives: Polyvinyl Acetate (PVA)

Cipadur 4203 is a solvent-free polyisocyanate, emulsifiable in water. Recommended for crosslinking aqueous polymer dispersions, such as polyurethane dispersions, polyvinyl acetate (homopolymer and copolymer) and polyacrylate. Crosslinking increases the resistance of the glue to heat, water, plasticizers and many organic solvents.

BayGranite™ is an inorganic hydrated alumina designed for use in polymer systems as a flame retardant and smoke supressive additive. BayGranite® 17 is more accurately designated chemically as aluminum trihydroxide, Al(OH)3, and is produced through processing of alumina-bearing feedstocks. Although BayGranite® 17 is a dry powder, when heated above approximately 220°C it decomposes into approximately 35% water and 65% alumina by weight. BayGranite®17 is a nonabrasive, low density material with a Mohs hardness index of 2.5 - 3.5 and a specific gravity of 2.42. Almatis BayGranite®17 ATH is compatible with polymer systems, and is designed for applications that require low-soda ATH products.

FlameGard™ is a ground Bayer hydrated alumina designed for specific application in polymeric adhesive backing of tufted carpeting to provide a level of flame retardancy to the carpet system. It is specially ground to maintain relatively coarse particle distributions in the median range of 22 to 26 microns and provides a high loading potential in high viscosity backing compounds. FlameGard ATH has a slight off-white or ivory color that is acceptable in most applications.
