The flowability of a resin depends on its viscosity and the solids content as well as the changes in the viscosity at elevated temperatures in the hardening glue line. A low flow — ability causes poor penetration of the resin into the wood surface and low bonding strengths. A too high flowability, on the other hand, leads to overpenetration of the resin into the wood and hence to starved glue lines. Flowability and hardening act against one another during the hot press curing process.
