(57) Abstract :
Process for making a polyisocyanurate composite which process comprises combining a polyisocyanate, a polyether polyol and a
trimerization catalyst with a to-be-bonded material to form a reactive composite, and allowing in a next step this reactive composite to
react at elevated temperature, wherein the amount of the reactive binder composition is 1 - 60 % by weight and the amount of the tobe-bonded
material is 40 - 99 % by weight, both calculated on the amount of the reactive binder composition plus the amount of th e
to-be-bonded material, wherein the amount of the polyisocyanate and the polyol is such that the index is 150 -10000, characterized in
that the polyol is a polyol having an average equivalent weight of 100 - 2500 and an oxyethylene content of at least 50 % by weight.
The reactive composite is claimed as well together with composites obtained from this process and from these reactive composites.
