Product Overview
Water Base Laminating Adhesive features quick speed, excellent flow leveling, and strong initial adhesion, high peeling strength and no foam in long-time continuous film coating. It is suitable for laminating paper with Bopp film. Film coated with the adhesive is characterized by high brightness and strong binding power. 2a Technical indexes: AppearanceBluish milk white liquid Viscosity25- 35s (25oC, coated with 4 cups) Solid content50A 2% PH value6.5-7.5 Validity period6 months at 5a 50oC Packing50KG plastic barrel 3 a Applying process and precautions: The compounding method is of dry-type, i.e. by use of dry-type compounding machine with drying channel and compounding roll with heating function. The drying temperature is about 60- 95oC. The compounding pressing roll is at a temperature of 40-70oC and the compounding pressure is about 8-20kg. It is suggested to dry the adhesive to 70%-90%, because the brightness of the compound is higher and the machine speed is higher under such condition. In such conditions, ita s better to reduce the temperature of the compounding pressing roll to below 5oCto avoid generation of large bubbles in the compound. In addition, the pressure shall be decreased slightly to avoid protruding out of the adhesive. In case complete drying process is used, the temperature and temperature of compounding pressing roll shall be the higher, the better on condition that the film is not burnt.
