Disadvantages of polyurethane waterproof coating

1, waterborne polyurethane waterproof coating construction temperature should be 5 ℃ to 35 ℃. 2, when using, do not mix water or other materials in this product. 3. Please use appropriate protective measures during construction, such as gloves. 4, good weather resistance, high temperature does not flow, low temperature does not crack, excellent anti-aging performance, oil resistance, wear resistance, ozone resistance, acid and alkali erosion. 5. The prepared slurry of waterborne polyurethane should be used up within 1 hour. 6, polyurethane waterproof coating environmental protection is relatively poor, pungent smell. Therefore, the average family uses more morning light waterproof coating and acrylic waterproof coating at home. Advantages: 1, the wear resistance of the paint film is strong, polyurethane coating is all kinds of coating wear resistance is better, at the same time excellent protection and beautiful decoration. 2. The adhesion of polyurethane paint film is strong. 3. The hardness adjustment range of the paint film is wide. 4, the construction of good adaptability, 0 ℃, room temperature, high temperature can be cured. 5. The paint film has good temperature resistance and can be made into high temperature resistant insulating paint with low temperature resistance of -40 ℃. 6, has excellent chemical resistance and oil resistance.
