EXCESTAR™
EXCESTAR is a liquid polymer for silane modified polyether sealants and adhesives. Its unique properties such as high flexibility, heat resistance, weatherability, and stain resistance, enable EXCESTAR to be applied in various markets including construction, industrial, and electronics. EXCESTAR products are toxic free, easy to use and the perfect choice where safety issues are a concern.

EXCESTAR™
Has multiple advantages compared with silane terminated polyurethane:

  • Home/Building/Construction
    • Metal roof sealant
    • Exterior/Interior sealant
    • Interior adhesive (flooring, wall, celling)
  • Industrial (Automotive/Transportation/Other)
    • Interior materials adhesive
    • Windshield adhesive
    • Joint sealing (panel, glass)
  • Electronics
    • Electric component adhesive

 

EXCESTAR™
(Silane modified polyether for sealants and adhesives)

  • Moisture curing with terminally reactive silicon groups
    • Environmentally friendly
    • Good Adhesion
  • High molecular weight
    • High flexibility
  •  Does not have urethane bond
    • Good Heat Resistance
    • Good weatherability

Polyols for Polyurethanes
Polyether polyols are key components used in the production of polyurethanes. AGC produces polyether polyol (PREMINOL™) from Propylene Oxide. Subsequently, AGC uses PREMINOL to produce silane modified polyether (EXCESTAR™) as a moisture-curable polymer. These polymers, available in the Americas, have high molecular weights exceeding 10,000. AGC employs an advanced catalyst process which results in polyols with ultra-low monol content, and a narrow molecular weight distribution.
