Abstract
A method of joining cellulosic fiber containing surfaces by means of a phenolic, phenol-resorcinol, or resorcinol resin based adhesive system, whereby at least one of the surfaces is treated with a cure promoter composition comprising a carbonate, prior to the adhesive system being applied and a cure promoter composition for phenolic resin based on resorcinol resin based adhesive system comprising a carbonate.
Claims27
A method of joining cellulosic fibre-containing surfaces, comprising the steps of treating at least one of said surfaces with a cure promoter composition comprising a carbonate and a water retaining and viscosity regulating agent, and thereafter applying an adhesive comprising a phenolic, phenol-resorcinol or resorcinol resin based adhesive system and contacting the surfaces.
A method of joining cellulosic fibre-containing surfaces, comprising the steps of treating at least one of said surfaces with a cure promoter composition comprising a carbonate, said at least one surface comprising a wood-based panel, and thereafter applying an adhesive comprising a phenolic, phenol-resorcinol or resorcinol resin based adhesive system and contacting the surfaces.
A cure promoter composition for a phenolic, phenol-resorcinol, or resorcinol resin based adhesive system, comprising between 66.7 and 85 weight & water, a water soluble salt of carbonic acid, a water retaining a viscosity regulating agent, and a base.
A fluid cure promoter composition for a phenolic, phenol-resorcinol, or resorcinol resin based adhesive system, comprising a water soluble salt of carbonic acid, a water retaining and viscosity regulating agent, and a base.
