Cemplete 8512 is a co-polymer of vinyl acetate – vinyl versatate-acrylic ester. It is characterized by high flexibility even at a low temperature and by good alkali resistance. These properties are transferred to its formulated compounds. It should be mixed with dry products and stored in water resistance packaging. On contact with water and under the action of mechanical shear, Cemplete 8512 produces a stable dispersion with properties comparable to those of the original one.

This product is a very versatile polymer that provides high levels of performance in cement-based and gypsum-based applications, as well as in non-hydraulic products. It is an ideal redispersable powder in situations where a multipurpose product is required.

Cemplete 8512 improves substrate adhesion flexural strength and freeze/thaw resistance and can be used in tile adhesive mortars, plasters, and exterior insulation finishing systems (EIFS). When used in repair mortars, it increases adhesive and cohesive strengths for greater durability and abrasion resistance. It is particularly recommended for the formulation of gypsum plasters because it improves water resistance, flexural strength, and mechanical resistance of finished products.

In joint compounds, it increases flexibility in order to tolerate greater substrate movement before cracking occurs. Cemplete 8512 allows increased water retention, an important aspect for thin-section mortar application on an absorbent substrate
