Cold tack of the adhesive is absolutely necessary in plywood production. Insufficient cold tack is usually seen as a typical adhesive problem and leads to complaints. An analytical method has been developed that proves, that many other factors also play a role. For example, cold tack decreases when the wood moisture content increases or increases with temperature. Based on the analytical data, a statistical model was build that predicts how cold tack reacts on the combination of many influencing factors. This model is used to educated plywood pro-ducers, leading to a reduction of failure in plywood production.
