Hydroxy Propyl Methyl Cellulose HPMC /CAS No. 9004-65-3/Coating Additives

 

HPMC Industry Grade (Hydroxypropyl methyl cellulose)

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.


 

Physical & Chemical Properties

Viscosity

 

Application

a) Construction

- Used as the water retaining agent and retarder in mortar to make it has good pumpability.

- Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.

- Used as paste enhancer of ceramic tile, marble and plastic decoration and reduce usage of cement.

- HPMC water retention property can prohibit too fast dry and cracking after the slurry spraying and enhanced strength after hardening.

 

b) Ceramic industry

Square Cut Nails

Square Cut Nails

The square section of a cut nail resists attempts at twisting the wood which can reduced movement helps keep the nailed structure stable. The square nail shank has a tapered section for increasing connecting area. Therefore, an excellent holding force is formed without splitting the fastening material. These special nails have a solid steel structure and are commonly used in wooden boat building and other hardwood construction projects.
