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.
