Commonly used putties include hydroxypropyl methylcellulose (HPMC), redispersible latex powder (RDP), etc.
Main functions
▶Water retention: It can effectively lock the moisture in the putty and slow down the evaporation rate of the moisture, thereby extending the open time of the putty and facilitating construction operations.
▶Thickening: Increase the viscosity of the putty, so that it is not easy to sag during construction, and ensure the uniformity and thickness of the coating.
▶Improve construction performance: Make the putty smoother, easier to scrape and apply, and improve construction efficiency and quality.
▶Improve the bonding strength of the putty: Enhance the bonding strength between the putty and the base layer to prevent the putty layer from falling off.
▶Improve the crack resistance of the putty: It helps to reduce cracks in the putty layer caused by drying and shrinkage.
▶Stabilize the performance of the putty: Maintain the stability of the putty performance under different environmental conditions.
