Traditional acrylic resin seals the substrate to form a dense paint film, and moisture cannot be released. With the increase of moisture pressure on the wall, the paint film is prone to foaming, cracking and fal...

AI Technical Summary

Problems solved by technology

Traditional acrylic resin seals the substrate to form a dense paint film, and moisture cannot be released. With the increase of moisture pressure on the wall, the paint film is prone to foaming, cracking and falling off due to condensation and other reasons, resulting in long-term moisture accumulation. Cause floating sand and decrease the cohesive force
