  • Patent number: 11180686
    Abstract: The adhesive system of the invention is especially useful in bonding replacement windows into vehicles. They allow for sufficient working time while still realizing a fast drive away time. The adhesive system is comprised of a moisture curable adhesive and a cure accelerator that may be applied using a simple single caulk gun and may be applied at ambient temperatures such as ?10° C. and about 45° C. The cure accelerator is comprised of a polyol having a backbone that has at least one amine in the backbone. The moisture curable adhesive typically is comprised of an isocyanate terminated prepolymer.

  • Publication number: 20190225736
    Abstract: A reactive plasticizer is comprised of a reaction product of an isocyanate having two isocyanate groups and a linear polyether monol. The monol has a weight average molecular weight of about 500 to about 2000 grams/mole. The amount of isocyanate and linear polyether monol are such that the isocyanate groups are in molar excess of the amount of alcohol groups and the reaction product has an isocyanate content of 0.1% to 1% by weight of the reaction product, The reactive plasticizer is particularly useful for formulating one part moisture cured polyurethane adhesives comprised of the reactive filler, an isocyanate terminated prepolymer, filler and a catalyst.
