DERIVED TIMBER PRODUCTS CONSISTING OF WOOD PARTS GLUED BY MEANS OF POLYISOCYANATES

摘要

Woodbase materials comprise wood pieces glued using an adhesive composition comprising an isocyanato-bearing prepolymer (prepolymer P) derived from A) a component A comprising A1) from 25 to 100% by weight of a triglyceride having two or more reactive groups which may react with isocyanate groups in an addition reaction (triglycerides A1), and A2) from 0 to 75% by weight of another compound having one or more reactive groups which may react with isocyanate groups in an addition reaction (component A2), and B) a component B comprising a polyisocyanate if desired, customary auxiliaries and additives if desired, an activator, and if desired, a filler, and adhesive compositions.
