Application of HPMC in Gypsum Plaster

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.
