SELF-SETTING URETHANE ADHESIVE PASTE SYSTEM

摘要

A rapid chemically curing adhesive paste composition which comprises a resin including a polyol having at least two hydroxyl groups, a hardener including a liquid polyisocyanate containing at least two isocyanate groups, a hydrophobic filler and a curing agent. Said adhesive paste may be made by mixing together a premixed resin component containing a filler and a catalyst and a premixed hardener component containing a hydrophobic filler. In either or both premixed components the filler may be a thixotropic agent. The use of said adhesive paste for assembling a foundry mold and the use of said mold for metal casting is also disclosed.
