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 to-be-bonded material is 40-99% by weight, both calculated on the amount of the reactive binder composition plus the amount of the 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.
