Arch low molecular weight polyols, in either solvent- or water-based formulations, have been a mainstay of the paint and coatings industry.
Higher molecular weight polyols, like Poly-G 20-28 and 85-29, are used for two-part, very high solid roof and deck coatings.
In addition, newly introduced Poly-A 27-2000 is utilized in sprayable polyurea-based formulas for use in tank and concrete coatings among other applications.
Poly-G polyols are used in high-solid, solvent-based and water-dispersible urethane adhesives.
And, most Poly-G 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-G VHP diols are favored due to their water compatibility and their ability to help reduce VOCs (volatile organic compounds). |
