The advantages and disadvantages of polyurethane waterproof coating are introduced

Polyurethane waterproof coating is a new type of polymer multi-functional material, it has a very good waterproof, anti-corrosion, insulation and other effects, so it is widely used in the exterior wall painting.
the advantages and disadvantages of polyurethane waterproof coatings
advantages:
1. Polyurethane waterproof coatings are now more common in building decoration of a coating, because it has a good environmental adaptability. When it comes into contact with moisture in the air, it cures, causing the grass-roots surface to form a seam-free
the
.
2. Polyurethane waterproof coating is easy to construct, it can be directly constructed on a dry or wet substrate, will not be affected, and the bonding force is still very strong. The polymeric substances in the polyurethane waterproof coating can also penetrate into the seams of the substrate, which can be seen to follow the type is strong.
3. The coating film in the polyurethane waterproof coating has high pull resistance and flexibility, even if the grass has cracking and telescopic conditions will not be affected, so its adaptability is very strong.
4. Qualified polyurethane waterproof coating is non-toxic and tasteless, is very green and environmentally friendly, and its wear resistance, acid and alkali resistance, low temperature resistance, oil resistance, etc. are very good.
5. Polyurethane waterproof paint can be adjusted according to user needs color, construction is relatively simple, maintenance is also very convenient.
:
1. Polyurethane waterproof coating on the construction requirements are relatively high, the construction temperature should be between 5 degrees C to 35 degrees C.
2. Polyurethane waterproof coating construction can not be mixed with any other materials, moisture can not be.
3. Polyurethane waterproof paint construction must wear gloves, to do a good job of protection measures.
4. The water-based polyurethane slurry must be used within 1 hour, otherwise it will not be used.
how to buy polyurethane waterproof paint
1. In the purchase of polyurethane waterproof paint, in order to ensure that it is genuine, it is recommended to go to a more well-known brand stores or formal building materials market to buy, and products need to have a certificate of conformity, product testing reports and CTC mark, these must be checked clearly.
. When shopping for polyurethane waterproof coatings, be sure to master some techniques to choose a more environmentally friendly waterproof coating, so that there is no impact on the health of the family.
3. When purchasing polyurethane waterproof coating, try to choose a coating film that is highly resistant to cracking, because the structure of residential buildings will be more complex, so we should pay attention to the crack bridging performance, requiring waterproof coating can resist more than 4 mm of crack deformation.
