Let me introduce PU FOAM to everyone today.PU FOAM adopts polymer foaming method and has a wide range of uses. This is the benefit of high expansion and small shrinkage. It is a pure natural adhesive and can be completed without the use of any active adhesives. It is usually used for doors and windows. Install caulking, bonding, plugging, heat preservation, sound insulation, and waterproofing. It has certain environmental protection and health performance. PU FOAM only needs a simple construction method to quickly ensure the insulation effect of the wall. It is a wonderful heat preservation artifact. Generally, the surface drying time is about 10 minutes (zone temperature 20℃), and the surface drying time varies with temperature and humidity. The curing time is about 4-6 hours in summer and 24 hours in winter.
Generally, the surface drying time is about 10 minutes (zone temperature 20℃), and the surface drying time varies with temperature and humidity. The curing time is about 4-6 hours in summer and 24 hours in winter.Under normal use conditions (with a covering layer on the surface), it can be calculated that its service life is not less than 10 years. In the temperature range of -10°C to 80°C, the cured foam maintains good elasticity and adhesion.
Door and window installation: sealing, fixing and bonding between doors and windows and walls.
Sound insulation and noise reduction: fill the gaps in the decoration of classrooms, broadcasting rooms, etc., which can play a role in sound insulation and noise reduction.
Daily maintenance: repair cavities, gaps, wall tiles, floor tiles, and floors.
Instructions for use: Shake the bottle vigorously until it is half full before use. After an hour, the colloid can swell to two to three times its original size. Large gaps can be filled layer by layer. After use, the bottle should be placed upright. When the colloid is fully cured, it is cut, polished and painted. If used outdoors, the surface will be coated with a layer of emulsifier protective
The uncured foam sticks to the skin and clothes, please do not touch the skin and clothes when using it. The pressure in the PU FOAM tank is 5-6kg/cm2 (25°C), and it should not exceed 50°C during storage and transportation to prevent the tank from exploding. PU FOAM cans should be kept away from direct sunlight and children are strictly prohibited. Do not throw away the empty can after use. Prevent open flames and do not touch flammable and explosive materials. The construction site should be ventilated, construction workers should wear work gloves, overalls and glasses during the construction process, and smoking is strictly prohibited. To prevent foam from contacting eyes, please rinse with water before seeking medical attention; if it comes in contact with skin, please rinse with water and soap.
