Condensation resin glues
Urea-formaldehyde and melamine-formaldehyde glues are also known as condensation resin glues. They belong to the oldest synthetic adhesive systems and are still widely used in present day wood processing.
These are prefabricated urea-based glues that are mixed with water before use. They are mostly used to join 2D materials with hot presses, and set at temperatures between 70°C und 120°C, which enables fast manufacturing processes. They form a hard adhesive joint with a moisture resistance suitable for most indoor applications.
Melamine resin glues are prefabricated 2C systems that are processed in hot presses. They generate a very hard glue joint and can achieve bonding qualities compliant with the A100 (DIN 68705) and stress group D4 (DIN EN 204) standards. This type of glue is often used in wet rooms and for outdoor applications.
