EXTON, Pa.—AGC Chemicals America Inc. has introduced two new polyols that the chemical manufacturer said can improve the performance properties of urethane sealants and adhesives used in demanding construction environments.
Preminol and Excestar polyether polyols are "highly pure, ultra-high molecular weight grades," AGC said in a Dec. 16 news release, enabling sealants and adhesives to cure faster, with greater tensile strength, durability, elasticity, heat resistance, paintability, weatherability and mechanical strength.
According to AGC, Preminol can be used with siding sealants on cement, composite board and sash; reinforced concrete wall joint sealants; wood and concrete floor adhesives; decorative and composite panel adhesives; roofing sealants; and plasticizers for silyl-modified polymers formulations.
The company said Excestar, a liquid polymer for silane modified polyether sealants and adhesives, is toxic free and can be used in metal roof sealants; exterior and interior sealants; and interior adhesives for flooring, walls and ceilings.
