Poly-Q 40-800 Polyol Arch Chemicals PU - Polyols ADHESIVE >> Solvent based SEALANT Poly-Q® polyols are used in high-solid, solvent-based and water-dispersible urethane adhesives. And, most Poly-Q® diols meet Title 21 Code of Federal Regulations for use in food packaging. Arch's 20 series diols, for most solvent- and sold-based adhesives, range in molecular weight from 425 to 4,000. The 55 sereies of Poly-Q® diols are favored due to their water compatibility and their ability to help reduce VOCs (volatile organic compounds). Poly-Q® polyols offer high molecular weights and excellent resilience, difficult to obtain with conventional, all-propylene oxide polyols Polyol. Can be used in high-solid, solvent-based and water-dispersible urethane adhesives and in food packaging. Provides high molecular weights and excellent resilience (difficult to obtain with conventional, all-propylene oxide polyols), water compatibility and ability to help reduce VOCs. High quality and reproducibility.
