Our quality measurement
The quality of WOTAI is recognized by international organizations. The QC step is an important link in our group, which connects every step from procurement to delivery. WOTAI has set strict quality inspections for each process. We select and inspect samples and record the inspection results, time, date and by whom. If any defects are found, we will remove the whole batch and check all programs.
WOTAI constantly revises existing formulas, focusing on practical value. Each solution is carefully tested multiple times to serve its true purpose.
Research & development
Wotai has continuously strengthened its core development capabilities and has become a leading Chinese institution in the global market. We are expanding product research and development with technical support. In addition, Wotai implements an eco-friendly strategy to protect Mother Earth and create substantial future value.
Wotai R&D Center provides modified solutions for customers with special requirements based on our years of research experience. Focus on efficient solutions for all walks of life.
HPMC is a natural polymer derived from cotton and wood pulp. The powder has good water retention and is an excellent dispersant and thickener.
HEMC/MHEC is an essential additive in tile adhesives, dry-mix mortars, putties and cleaners. It has strong adhesion and high temperature resistance.
HEC is obtained from cellulose. It has many uses in real stone paint, latex paint and decorative paint.
RDP powders are obtained by spray drying of latex dispersions. RDP has fast solubility in water and improves mortar strength and cohesion.
Calcium formate is a construction additive as well as an animal feed preservative. It has an antifreeze effect and accelerates the mortar strength.
PP fiber is a man-made fiber made by polymerizing propylene. It is easy to work with and provides additional toughness and impact resistance to the mortar.
HPS dissolves in water to form a transparent viscous liquid. It achieves better freeze-thaw stability and has a fast thickening effect.
SM is a water reducer. It reduces water consumption but increases the strength and density of the mortar. It has good compatibility with various cements.
PCE is an effective water reducer in self-leveling, grouting materials, and grouting agents. It increases density and reduces shrinkage cracking.
Cellulose ether family (3)
-
Architectural-grade HPMC enhances water retention. Cement or concrete often dries too quickly due to insufficient hydration. This basically causes cracking.
-
HEMC and HPMC have similar roles in building materials. It’s just that HEMC has a higher gel temperature than HPMC, which means HEMC is more stable in hot weather.
-
HEC has the strongest protective colloid ability among all cellulose ethers. Its water retention level is much higher than methylcellulose. Good liquidity control.
RDP Powder category (3)
-
RDP – flexible grade is mainly used as putty, paint and interface mortar. It is suitable for exterior wall putty, anti-crack mortar and waterproof mortar.
-
RDP – Rigidity grade is commonly used in insulation mortar and masonry mortar. Generally used for interior wall putty, bonding mortar and ordinary mortar.
-
WOTAI R&D Center specializes in designing and creating RDP formulations that meet your requirements. We will recommend the most suitable formulation for your project.

Application senarios
Cellulose ethers act as thickeners and stabilizers in many industries. Including construction, food, pharmaceuticals, personal care and daily chemicals. WOTAI cellulose ethers are mainly used in construction and daily chemicals.
Hydroxypropyl Methylcellulose is short for HPMC. It’s the most frequently used polymer. Depending on the corresponding viscosity, it can be used for adhesion, emulsification, bonding, suspension, film-forming, and gelation.
Redispersible latex powder is also called RDP powder. It is obtained through a complex spray-drying process. Currently, it is used as a chemical additive in building materials.
