What is resorcinol adhesive used for?
The most common application for resorcinol glue is in adhering the plies of exterior and marine grades of plywood. It is strong. Currently one of its main uses is to put together plywood, laminated support beams and other wooden structural elements.
What is Cascophen?
Cascophen phenol formaldehyde resins are high performance resins used to bind oriented strand board, softwood plywood and laminated veneer lumber for both structural and non-structural use in interior and exterior applications.
What is resorcinol formaldehyde used for?
Resorcinol reacts with Formaldehyde to form polymers. Resorcinol formaldehyde resins cure at room temperature. They form a very strong bond that is resistant to moisture, acids and weathering. Resorcinol resins are used as adhesives for wood veneers, plywoods, and for rubber-textile laminates.
Does epoxy stick to resorcinol?
All exterior/marine/aircraft ply is glued with resorcinol. But it doesn’t fill gaps like epoxy. Many of the criticisms of resorcinol – the tight fits and the high clamping pressure – are also limitations of the polyurethane and waterproof PVA glues. Epoxy is the only glue at the moment which is reliably gap filling.
What is white glue made of?
PVA is made up of a water-based emulsion of a widely used type of glue, referred to variously as wood glue, white glue, carpenter’s glue, school glue, or PVA glue. PVA is largely used in glass fiber-reinforced plastics to improve the stress and antishrink properties.
Does resorcinol dissolve in cold water?
Resorcinol (or resorcin) is an organic compound with the formula C6H4(OH)2. It is one of three isomeric benzenediols, the 1,3-isomer (or meta-isomer)….Resorcinol.

What is PU glue?
Polyurethane adhesives, also known as PU adhesives, are adhesives used for higher strength constructions and can be used as both inelastic and permanently elastic adhesives. They are based on polymers, but often contain other components such as various additives. The glue is paste-like and shrink-free.
