Abstract:
Disclosed is an aqueous bonding composition comprising: (A) a saccharide; (B) a phosphate; and (C) at least one neutralizing agent selected from ammonia and an amine compound having at least one hydroxyl group. The aqueous bonding composition is excellent in balance among bending strength, bending strength under wet condition, water-absorption thickness expansion coefficient and peeling strength and scarcely causes metal to rust. The aqueous bonding composition can be usefully used to produce a wood-based material.

Abstract:
A method for manufacturing coated profile members (10), wherein a foil (16, 36) is cut to a predetermined width and wrapped around the profile member so as to form a butt seam extending in a longitudinal direction of the profile member, characterised in that the foil (16, 36) is cut by means of a cutting beam (24) in a condition in which an edge strip of the foil projects beyond the profile member (10), while a face of the profile member is used as reference for the position of the cutting beam.
Abstract:
A method of surface sealing a porous fibrous substrate is provided. According to the method, a porous fibrous substrate possessing a moisture content and a surface with pores is provided. A sealant composition is applied to a surface of the porous fibrous substrate and permitted to penetrate the surface pores of the porous fibrous substrate and undergo cure while participating in a foaming reaction with the moisture content to establish a water-resistant polymeric foam sealant impregnated into the porous fibrous substrate. The water-resistant polymeric foam sealant contains a polyurethane and/or polyurea.
