The adhesive is designed for automatic nozzle application. It is very important to protect the applicator and production line with water-free release agent.
The adhesive is spread on the wood surface, and the wood is pressed together. The required strength is achieved within 1-3 minutes after the pressing has ended. The pressing time strongly depends on the moisture content of the wood. The final bond strength depends on the type of wood and the amount of adhesive used.
