Paint Remover 5 Ltr

RXSOL MPC 1013 is particularly used in aircraft industry because of its non-reactivity with aluminium, copper, brass their alloys.

The condition of metal surface is a vital factor affecting paint adhesion—the greater the surface, the better the adhesion of the coating. The increased area resulting from sandblasting, etched surface, porous castings and from conversion coatings have added to the difficulty of paint removal. Not only do these conversion coatings increase the surface area of the metal, but the porous nature of the inorganic film enables the paint to penetrate into the crevices and form a deep-rooted and firmly bound bond with the surface. The increased surface and the penetration of the paint into the porous inorganic film retards the stripping operation. Using the same paint and the same stripper, the coating on an untreated surface will wrinkle and lift away rapidly in large sheets. On the other hand, the stripping time of the piece having a conversion coating is greatly increased,- and the appearance of the stripped paint coat is considerably altered. Instead of the customary large sheets of paint and a clean surface, the coatings from phosphated, chromatized or anodized work, break away in small uneven pieces, leaving much of the paint coat still clinging to the metal.

Heavily pigmented coatings affect the efficiency of the stripper. The high pigment content plus the density of the pigment retard the solvent stripper from penetrating through the coating to the base metal to break the bond between the metal and the coating. Such coatings are usually found on refrigerators, washing machines, etc., where high chemical and moisture resistance are desirable. The stripping time for these coatings is considerably greater than a coating coning the same resin with a lower pigment content.
