Biocidal preparation "Teflex Protection for Metal" effects on properties of building composites based on inorganic cements

The tests have proved the biocidal properties of the admixture “Teflex Protection for metal”. Thus, the admixture introduction in quantity of ≥1 % makes a cement stone fungi resistant, while its increase to ≥7,5 % provides the composite with fungicidity. For plaster composites the increase of biostability is reached at the preparation introduction in concentration of ≥5 %. Moreover, the admixture shows a plasticizing effect that reduces water requirement and water absorption of plaster materials.
