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).
Elastomers made from TDI prepolymers, using Poly-G 55-112, 55-56 and 55-37, offer improved tensile strength, tear resistance and resilience compared with conventional polyols.
Elastomers based on MDI prepolymers, made with these same polyols, promote excellent resilience and compression set properties.
Poly-G 85-36, a VHP polyol, is used in prepolymers and curing agents for room-temperature cure and tire-fill elastomers.
It improves resilience, compression-set and glass transition temperature.
A new high-performance elastomer, incorporating the 55 series of diols with high performance polyols such as PTMEG, has been designed to obtain the best features of each.
Poly-G HQEE is an aromatic diol chain extender used in high performance elastomers and TPU applications.
Poly-G 70 series polyols are amine or sucrose based polyols designed for rigid foam applications.
Poly-G 37-600 is used in rigid foam systems to reduce viscosity and balance stoichiometry.
Poly-G 70-600 is designed to be used in potting compunds, "thermobreak" aluminum winodw insulation, bowling balls and skate board and roller skate wheels.
Poly-G 71-530 exhibits good compatibility with blowing agents and is used as a base polyol for frothing rigid urethane foam.
Both Poly-G 74-376 and Poly-G 74-444 are used in high density molded foams due to their low hydroxyl values and viscosity.
In addition, both polyols can be blended with autocatalytic polyols to vary the reactivity for various applications.
Poly-G 76-120 was developed to reduce the surface friability of rigid urethane foams.
While serving this purpose, it is more widely used in non-foam urethanes.
Poly-G 76-635 is used as a chain extender for coatings and as a hardner (cross-linker) for elastomers.
Arch offers two tetra-functional rigid polyols Poly-G 40-770 and Poly-G 40-800 used in rigid foams and elastomer applications. |
