The APU Series is a new family of HDI aliphatic prepolymers using polyurea technology. All prepolymers are monomer extracted to levels of 0.1%. The prepolymers are available from 6% to 20% NCO. Specifically designed or custom Prepolymers may be manufactured for client needs. All prepolymers are 100% solids. These prepolymers may be supplied with solvents upon request. The APU # indicates the % NCO. APU-16 is one our standard workhorse prepolymers in polyurea formulations and well as in the polyaspartic series of products to deliver specific performances.
WB APUs are a new family of water-based aliphatic prepolymers using 2K WB polyurea technology. The proprietary isocyanate prepolymers are designed to be reacted with our water-based polyols to produce high strength UV resistant coatings while enhancing other properties such as abrasion resistance, adhesion, tensile strength and extended gel, tack free times and wet-out times. These solvent-free polyisocyanate prepolymers are offered in specific NCO content grades to deliver the desired properties of your end products and formulation requirements.
