摘要 |
<p>Polyurethane sealant system and method of forming a high tensile strength seal on glass and/or metal. …<??>A polyurethane sealant includes a polyurethane having terminal isocyanate groups and a dual curing catalyst of an organic bismuth compound and an organic tin compound. The polyurethane is a reaction product of a liquid poly (lower)alkylene polyol having a molecular weight of 6,000 or more and three to five hydroxyl groups and a sterically unhindered aromatic diisocyanate. The polyurethane sealant may be used in conjunction with a silane based primer and when applied to glass surfaces provides a high strength and rapidly curing seal.</p> |
