Redispersible latex powder improves the crack resistance of putty in the following ways
January 22nd 2025
The addition of HPMC to gypsum plaster formulations can significantly improve its construction performance and final physical properties. Specifically:
Improved construction performance: Gypsum plaster added with HPMC has better fluidity and water retention, making construction smoother, and is especially suitable for plastering and leveling large areas.
Improve surface quality: Due to the lubrication and water-retaining properties of HPMC, the surface of gypsum plaster is smoother and more delicate after drying, reducing the occurrence of bubbles and cracks.
Enhanced adhesion: HPMC improves the adhesion between gypsum plaster and different substrates, ensuring the firmness of the plaster layer and avoiding shedding and cracking.
Extended operable time: Due to the water-retaining properties of HPMC, gypsum plaster has a longer operable time during construction, allowing construction workers more time to make adjustments and trimming, reducing material waste.
