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. Please contact our engineering group for customization solutions for your specific requirements.
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.
