Abstract
The present invention relates to a method of gluing wood based materials by providing an adhesive system onto wood based materials followed by curing, the adhesive system comprises a melaminic amino resin and a phenolic resin composition, wherein the phenolic resin composition comprises an acid and a phenolic resin. The invention also relates to an adhesive system and a stable phenolic resin composition as well as wood based products obtained by the method or through the use of the adhesive system.
Claims13
A method of gluing wood based materials by providing an adhesive system onto wood based materials followed by curing, the adhesive system comprising a melaminic amino resin and a phenolic resin composition, wherein the phenolic resin composition comprises an acid which is a volatile acid, and a phenolic resin, which is a resorcinol-formaldehyde resin or a phenol-resorcinol-formaldehyde resin, wherein the weight ratio of melaminic amino resin to phenolic resin is from about 0.2:1 to about 10:1, based on dry matter.
A wood based product obtained by a method of gluing wood based materials by providing an adhesive system onto wood based materials followed by curing, the adhesive system comprising a melaminic amino resin and a phenolic resin composition, wherein the phenolic resin composition comprises an acid which is a volatile acid, and a phenolic resin, which is resorcinol-formaldehyde resin or a phenol-resorcinol-formaldehyde resin, wherein the weight ratio of melaminic amino resin to phenolic resin is from about 0.2:1 to about 10:1, based on dry matter.
