Duvilax BD-20 additive for building mixes, 1 kg

Plasticized polyvinyl acetate dispersion used in construction as a plasticizing and air-entraining additive for mortars, plasters, cement screeds and other building mixes in an amount of up to 5% by weight of cement or lime. It supports the workability of the mixture, increases its adhesion, flexibility, and ultimate strength, and reduces water permeability.

It is added to the mixture together with the mixing water. It is also used in the production of interior coatings, where it serves as a dispersion binder and ensures abrasion resistance. Diluted Duvilax BD - 20 with water at a ratio of 1:4 can be used for priming or soaking absorbent substrates before applying building cement or dispersion adhesives and fillers.

In its undiluted form, it is used for gluing paper, cardboard, and other materials in the printing or paper industry or for gluing textile wallpapers in interiors. It meets the requirements of the standard EN 934-3: 2003, T.2 - plasticizing and air-entraining additives for masonry mortars.

In building mixtures, it acts as an additive that reduces absorbency while increasing the vapor permeability for water vapor and mechanical resistance.
