摘要:
High green strength reactive hot melt adhesives are prepared using relatively low levels of reactive acrylic, and may be prepared with one or more difunctionals having cyclic or polycyclic structures.
摘要:
The invention provides adhesive and sealant compositions prepared from urethane prepolymers. The urethane prepolymers are obtained by reacting the novel urethane diols, polyester polyols and polyether polyols with an excess of diisocyanate. The urethane diols are prepared by reacting excess low molecular weight diols and diisocyanates. The invention is particularly useful in end use applications such as panel lamination.
