Pu Foam

Environmental protection polyurethane foam joint mixture

DESCRIPTION
This product is a kind of single component polyurethane foam, moisture curing, multi-purpose filled elastic sealing materials. The elastic foam solidified body with excellent performance of caulking, bonding, sealing, heat insulation, sound absorption, thermal expansion and contraction, is a kind of environmental protection and energy saving, convenient use of building materials.

MAIN INGREDIENTS
Isocyanate, Polyether, Silicone Oil, Dimethyl Ether, Propyl Butane, etc.

FEATURE
1. The normal use of container temperature 5? ~ 35?;
2. The best temperature of 18? ~  25?;
3. After curing temperature tolerance range - 30? ~ 80?;
4. Foam surface of the sticky time is 10 ~ 15 minutes, about 60 minutes of foam curing, and in 3 ~ 5 hours to achieve stability;
5. Foam can be firmly adhered to the vast majority of the surface of the material, but not including Teflon, silicone resin and other materials, such as the use of the metal parts, should be on the surface of the coating;
6. This product belongs to green building materials, no harm to human body after curing.

APPLICATION
Suitable for sealing leaking stoppage, filling the joints, fixed bonding, insulation, gas fill the vacancy, lack of engineering structure hole and various rupture gap, etc. Especially widely used in sealing up or Aluminum Alloy plastic steel doors and windows and the wall between the waterproof and.

INSTRUCTIONS
1. Remove the substrate surface dust, dirt, grease, and water to be filled with a little wet part;
2. It can be used normally in the temperature range from 0 ? ~ 40 ?. If it is used in cold season, it is suggested that the tank can be preheated in the environment of 30 ? to ensure the use effect;
3. Before the construction of the tank under shake vigorously for one minute or more, please keep the tank construction inversion;
4. Vertical slots must be filled, bottom-up, injection amount to the volume needed to fill 2/3 (note expansion foam);
5. Per tank construction is completed, please cleaning thread parts with polyurethane glue gun, each successive construction is completed, please clean the barrel with polyurethane glue cleaning agent, so as to avoid clogging curing;
6. Please repair and cutting in foam after curing completely, it is worth noting that the cut foam will reduce the strength and reduce skin foam sealing foam waterproof effect;
7. Polyurethane foam sealant not resistant to ultraviolet, paint do other materials in the curing of the foam surface (such as cement, mortar, sealants, paints etc.).

ATTENTION
1. This product to avoid direct sunlight, cool and dry, and the temperature is not more than 50?; Don't store in the moist environment, so as to avoid leakage due to corrosion caused by tin;
2. It is strictly prohibited upside down or side, in order to avoid the valve sticking phenomenon;
3. Empty cans after piercing or burning;
4. Close to open flame or contact with flammable and explosive materials;
5. This product may be used in the production of combustible mixed gas, so the construction site should have ventilation conditions. Construction workers should wear work gloves and goggles, and don't smoke;
6. This product is not cured when there is a strong viscosity, while the clothing fiber permeability, Don't touch the use of clothing;
7. Please put the cans in the place where children can't reach. If the foam is in contact with eyes or skin, wash with soap and water immediately. If you feel unwell, go to the hospital immediately.
