TECMA-ADH is a milky liquid resin mono-component emulsion, based on an aqueous dispersion of modified acrylic resins with special additives, which has been especially developed to be used as adherence bridge between materials. Its special adhesive characteristics are consistent long after being applied (more than 24 hours), which allows enough working time and a perfect adherence between the support and the new materials (mortar, concrete, etc.) even when several hours have passed between the application of TECMA-ADH and the application of the new material. TECMA-ADH forms films which are clear, adhesive, flexible, water-resistant and little affected by temperature.
