A stable, heat resistant colloid stabilized waterbased bicomponent wood adhesive based on vinyl acetate and N-methylolacrylamide as a cross-linking agent and also including an aromatic and/or cyclo aliphatic monomer, such as 2-phenoxy ethyl acrylate and/or isobornyl methacrylate, and methyl methacrylate. The colloid system contains a high molecular weight partially hydrolyzed polyvinylalcohol and one or more intermediate hydrolyzed polyvinyl alcohols.
A floor surface is described which involves a plurality of planks joined together using a 2-part adhesive system. Pre-applied adhesives on one or more floor panels are further described as well as methods of installing the floor panels to form a floor surface.
