finishingpolyurethanesolvent-based

Solvent-based two-component polyurethane varnish. Suitable for finishing resinous coatings or concrete floors. Good mechanical and chemical resistances. Matt appearance. Description Transparent formulation based on aliphatic polyurethane resins. It resists ultraviolet rays, acid rain and the action of various acids (for further details contact Sivit Technical Assistance). FINISOL TRASPARENTE OPACO It forms a film that maintains good flexibility and good resistance to abrasion and scratching. It contains UV filters that preserve the surface from photooxidative degradation. Matte appearance. Use Painting of concrete floors. Finish for resin coatings. Dustproof impregnation of cement and brick products. Particularly suitable for battery storage areas. Protection of metal surfaces not subject to corrosion. Support The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1,5 N/mm2. Preparation of the support Each support must be cleaned, degreased and free of old coatings during detachment. Abrasive superficially to promote adhesion. It is recommended to use abrasive papers with a grain greater than 150, clear if possible. After abrasion completely remove dust from the surface. As top-coating of resin coatings, it is necessary to proceed with the application by verifying the coating time of the previously applied product. Concrete and brick surfaces must be solid, seasoned, leveled, absorbent, not polluted by oils, dust or other substances. Mechanically prepare the surface by sanding or grinding.
