Modified HPMC for Gypsum Plaster

Brif introduction

Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.

Product properties

1. Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.

2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.

3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.

4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.

COOPERATION

WOTAI, a professional factory and distributor provides HPMC for gypsum plaster. HPMC is the perfect additive to increase the tensile strength of your gypsum plaster and other building materials. It is an adhesion agent that tremendously improves flexural strength and bonding strength.

 

Gypsum plaster is also called POP. It’s white cementation produced by dehydrating mineral gypsum, partially or completely. It’s often added with decelerators or hardeners. Employed with water in a plastic state, it sets and hardens by the chemical reunification of gypsum and water. WOTAI’s high-quality HPMC products can help your gypsum plaster perform better.
