SikaMelt®-209 is a versatile pressure sensitive hot melt adhesive based on thermoplastic rubber. It has high tack, strong initial adhesion combined with good cohesion properties. PRODUCT BENEFITS Low odour High tack High peel strength Good cohesion Low fogging Areas of Application SikaMelt®-209 is suitable to equip paper, polymer- and metal foils, textiles, foams and a big variety of other materials with self-adhesive backsides. SikaMelt®-209 is not to be used on substrates containing monomeric plasticizer. 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. Application With adequate processing equipment SikaMelt®-209 can be applied directly or in a transfer method. It can be applied as film, dot, bead or spray application. For automated applications a suitable filter system is required. Due to the better adhesion performance the direct method is usually chosen whenever possible. The transfer method is often used in combination with substrates that are porous and absorbing such as foams or when they are sensitive to high temperature such as thin PE films. To protect the adhesive surface against dust, light and oxygen it is necessary to cover the adhesive film with silicone coated paper or foil.
