Decorative varnish OPACO A+B

protectivefinishingpolyurethane

Water-based two-component polyurethane varnish. Suitable for finishing resinous coatings or concrete floors. Good mechanical and chemical resistances. Matt appearance. Description Two-component product based on cross-linked polyurethane dispersion with a hydrophilic aliphatic polyisocyanate. The film obtained after the coalescence and crosslinking phase has the following characteristics: high anchoring properties on various supports excellent mechanical properties good abrasion resistance good resistance to solvents excellent resistance to atmospheric agents good resistance against ethyl alcohol matt appearance Use Finishing of resin coatings. Protective transparent for decorative coatings and paints. Painting of concrete floors. Preparation of the support Surfaces must be cleaned, degreased and free of non cohesive parts As top-coating resin coatings, it is necessary to check the coating time of the previously applied product. Sand superficially to promote adhesion. It is recommended to use clear sand papers with grain 150 or finer. After sanding completely remove dust from the surface. Chalking substrate or very absorbent should be treated with a coat of PAVIWATER T68 or PAVIWATER TES, both diluted 1:3 with water. Application At the time of application, pour component B to component A, mixing carefully with a mechanical mixer.Apply the mixture by roller with a consumption of 0,100 kg/m2. For the application it is recommended to use suitable medium-hair rollers.To obtain a non-slip surface, add 3% by weight of SFERETTE DI VETRO FINI to the mixture (see table).Avoid films that are too thick to allow the correct development mechanical chemical features of the film.
