Polyurethane hot melt with high initial strength for sandwich panels bonding SikaMelt®-675 IS is a reactive polyurethane hot melt adhesive that cures on exposure to atmospheric humidity. With its high initial strength it is best suited for bonding of sandwich panels. - High green strength - Broad adhesion spectrum - Low odour - PRODUCT BENEFITS - High green strength - Broad adhesion spectrum - Low odour - Preeminent coating properties - Medium open time for Sandwich Panel Bonnding Areas of Application SikaMelt®-675 IS is suitable for permanent bonding of polar plastics as well as for wood, foam, textiles, painted and primed steel. Non polar plastics like PP and PE can be bonded after proper physical pre-treatment. It is used for automative interior trim lamination as well as for Sandwich Panel applications. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility. Surface preparation Surfaces must be clean, dry and free from grease, oil and dust. Based on the surface and type of material, a physical or chemical pre-treatment might be required. Type of pre-treatment must be determined by preliminary tests. For metals best results are achieved, if substrates are heated up between 40 °C and 60 °C prior the assembly process. Application With adequate processing equipment SikaMelt®-675 IS can be applied as film, dot, bead or spray application. For automated applications a suitable filter system is required.
