Usage / Purpose PU038 is mainly used for the structural bonding of corner angles of aluminum windows and doors. Bonded parts can be powder coated afterwards. Key Benefits • Solvent free • Thixotropic - will not drip • Good weather resistance • Easy to apply Protective Equipment USE IN WELL VENTILATED CONDITIONS and ensure all recommended protective equipment is worn during handling & use of this product. For full recommendation, refer to safety data sheet. Surface Preparation • Surfaces must be clean, dry and free from dust, grease and any other substances liable to impair adhesion. • To improve adhesion of PU038, the cleaning of previously painted aluminium surfaces with AA290 PU Cleaner or acetone is recommended. • Pre-treatment of bare aluminium surfaces is also recommended using chromate, phosphate or anodizing.

Two Part Corner Cleat Adhesive Application • Unscrew and remove static mixing nozzle. • Before placing the cartridge into the gun, make sure that the two plastic discs at the end of each part of the cartridge are in place. • These discs allow good distribution of pressure from the gun to the entire surface of the piston. • To ensure a homogeneous mixture, the first 20 g of newly mixed adhesive should be discarded. • The homogeneous mixture is achieved by means of pressing the gun directly to the surface where the adhesive is being applied (see Figure 1). • After application or if there is a long...
