KLEIBERIT 433.3 adhesive for 3D lamination of MDF fronts with PVC film. Water-based PU dispersion; reactivation from 55 °C. Packaging: 26 kg. Manufacturer: KLEIBERIT, Germany.
KLEIBERIT 433.3 adhesive — water-based polyurethane dispersion for 3D lamination. Manufacturer: KLEIBERIT, Germany.
Applications and features
Designed for laminating routed MDF furniture fronts with thermoplastic furniture films, particularly PVC, in membrane and vacuum presses. Verify the compatibility of the specific film and substrate by trial bonding.
A white dispersion with lower viscosity. Its viscosity of about 800 mPa·s distinguishes this grade from variants around 2200 mPa·s.

Values are guides for process selection. Heat resistance depends on materials and test conditions; it does not indicate a permissible continuous service temperature.
Preparation and application
Spray the adhesive onto dry, dust-free MDF. Absorbent edges and routed areas may need a second coat. Dry the adhesive film before pressing. The stated temperature refers to reactivation of the adhesive film, rather than the press heater setting. Adjust the process to the film, component geometry and equipment.
For two-component use, add 5% KLEIBERIT 807.0 by adhesive weight: 50 g per 1 kg, or 1.3 kg per 26 kg canister. Add the hardener gradually while stirring. Prepare only the amount needed for the process.
At about 20 °C, the mixed adhesive has a pot life of approximately 8 hours; allow roughly 30–60 minutes for drying. Guide consumption: about 50 g/m² on smooth MDF and 100 g/m² on routed areas.
Storage
Keep in tightly closed original packaging and protect from freezing. Check the current technical data sheet and batch label for storage conditions and shelf life.
