PU 3000 - TECHNICAL CHARACTERISTICS
PU 3000 is a two-component contact adhesive based on polyurethane resin.
PU 3000 is used to bond leather or other material to the instrument panel in a car.

The adhesive is applied by spraying both surfaces to be bonded. The viscosity of the adhesive is adjusted for application by spraying. Before use, 5% of HARDENER HTF (40g) is added to the adhesive. Thus prepared adhesive is usable for 4 hours. We recommend bonding at a temperature of 20℃ to 30℃. INTERSOL NF is used as a cleaning agent for the instrument panel before the application of the adhesive. Surfaces on which the adhesive is applied can be joined immediately after application or later by heat activation. We recommend the activation by temperature. The temperature of activation is 40℃ to 80 ℃. We recommend the application of two coats. The drying time for every coat is 20 min. An industrial fan can be used for activation. The bonded joint is resistant to elevated temperatures.
