AI Technical Summary
Technical Problem
Existing sealing primers have problems such as long surface drying time, easy cracking of the coating, and lack of leveling function.
Method used
A composition of component A and component B with a weight ratio of 1:1.8-2 is used. Component A consists of styrene-acrylic emulsion and silica sol, while component B consists of silicate cement, sulfur-aluminate cement, gypsum, etc. The liquid and powder are prepared by mixing and then mixed to form a sealing primer.
Benefits of technology
Sealing primers have excellent penetration, sealing and adhesion properties. The coating is not prone to cracking after application, has a leveling function, and has a short surface drying time, thus improving construction efficiency.
