HPMC

HPMC hydroxypropyl methylcellulose is an essential component of any EPS bonding mortar. WOTAI HPMC allows proper adhesion between the EPS insulation board and the mortar while providing a waterproof barrier. It prevents moisture from seeping into the EPS and causing further problems.

RDP Powder

RDP powder from WOTAI is used in EPS bonding mortar to improve efficiency and maximize product performance. The EIFS requires a certain amount of RDP powder to function properly. Adding RDP powder to the EPS bonding mortar improves the overall performance of the EIFS.

EPS Adhesive Formulation with WOTAI Additives

EPS Adhesive is a cement-based adhesive that is ideal for year-round use. This product comprises Portland cement, texturing aggregate, mineral fillers, hydrated lime, and reinforcing fibers. EPS Adhesive has excellent durability, frost resistance properties, and quick drying times. Storing the EPS Adhesive is important to ensure consistent performance throughout the application process.


Cement-based plaster is essential for EIFS/ETICS components. When added with HPMC, it provides excellent adhesion and cohesion to the substrate, indispensable for a successful EIFS/ETICS installation.

FAQ

Have any questions? We’re here to help you out.

Why do we add HPMC in EPS adhesive?

HPMC is an essential part of EPS adhesive formulation. Adding HPMC grants the product better durability, fast-drying, and frost resistance qualities. To ensure optimal performance of this adhesive during the application, it should be stored correctly. Additionally, reinforcing fibers are added to provide increased strength and flexibility.

Is HPMC necessary for EPS Bonding Mortar?

HPMC is an essential component of any EPS bonding mortar. HPMC allows proper adhesion between the EPS insulation board and the mortar while providing a waterproof barrier. It prevents moisture from seeping into the EPS and causing further problems.

 

WOTAI HPMC is a must-have additive for EPS Adhesive. EPS with HPMC offers impressive durability, rapid drying, and excellent frost resistance. It must be stored correctly to maximize the adhesive’s performance during its application process. Additionally, reinforcing fibres are present in the EPS Adhesive, which provides better strength and flexibility.

Why it is important to have redispersible polymer powder in EPS bonding mortars?

RDP powder is used in EPS bonding mortar to improve efficiency and maximize product performance. The EIFS includes bonding mortar, anti-cracking plastering mortar, and exterior water-resistant Putty. Each layer of the EIFS requires a certain amount of RDP powder to function properly. Adding RDP powder to the EPS bonding mortar improves the overall performance of the EIFS.
