MP2701 in Cement and Gypsum Systems

MP2701 is a VAE powder with a minimum film forming temperature of 3 °C, positioned as a single grade for cement and gypsum systems. The claim is worth testing rather than assuming.

Two Setting Chemistries

Cement sets by hydration in a strongly alkaline pore solution. Gypsum sets by crystallisation in a near-neutral solution. A polymer that works in both has to tolerate both environments.

MP2701 is formulated to do that, with a hard film that gives cohesion in a cement matrix and a mechanical key on paper and board in a gypsum compound.

Dosage Across Systems

Cement-based applications usually sit at 1 to 3 percent, gypsum joint fillers at 2 to 4 percent. The gypsum system needs more because the matrix carries less strength of its own.

Because the grade is hard, the dosage can be adjusted for adhesion without softening the mortar, which keeps sandability and trowel feel consistent between products.

Where It Compromises

A single grade cannot be the best answer everywhere. In a highly flexible ETICS base coat, a softer powder will outperform it.

The value of MP2701 is inventory simplification across a range of moderate applications, not replacing specialised grades at the extremes.
