VAMCELL® MPM850 HPMC Modified Cellulose Ether for Tile Adhesives and Skim Coats

VAMCELL® MPM850 is a modified methyl hydroxypropyl cellulose ether specially designed for C2/C2T/C2TE grade tile adhesives and other cement-based dry mortar systems.

It delivers excellent anti-slip performance, high bond strength, and smooth workability, ensuring superior tile adhesion even under challenging construction conditions.

With its optimized viscosity and rheological balance, MPM850 improves open time, trowelability, and water retention, providing consistent performance across tile adhesives, skim coats, and EIFS (External Insulation Finishing Systems) formulations.

Key Benefits:

Superior anti-slip performance — prevents tile sagging on vertical surfaces.

Excellent bond strength — ensures durable adhesion and long-term stability.

High water retention — enhances cement hydration and open time.

Good thickening efficiency — maintains mortar consistency and smooth texture.

Excellent workability — easy to mix, spread, and apply on site.

FAQ

What applications is MPM120 suitable for?

It’s mainly used in cement-based tile adhesives and tile grouts to enhance workability and bonding strength.

Does MPM120 affect setting time?

Only slightly — it maintains fast cement hydration while improving consistency.

Can MPM120 be combined with RDP?

Yes, it works synergistically with VINNATE® RDP for better flexibility and adhesion.

How should MPM120 be mixed?

Add slowly into cool water under stirring; disperses quickly without lump formation.

How should it be stored?

Store in a dry, ventilated place below 25°C; shelf life is 2 years if kept sealed.led, dry, and below 25°C. Avoid moisture — shelf life is 2 years under proper storage conditions.
