Apply on well cleaned sanded surfaces; make sure the substrate is free from dust, fibres, dirt and surface condensation. On the metal plates, remove any residual oxide and degrease with anti-silicone thinner. Thoroughly mix the mastic with 1.0 – 3.0% catalyst paste (benzoyl peroxide), bearing in mind that the quantity of catalyst required depends on the operating temperature and the required processing times. The recommended temperature range for use is between 12 and 30 ° C. It is applied manually with a spatula in one or more coats until the required thickness is reached. Sandable after 20 minutes from application at 23°C. In its original packaging, the product can be used for 12 months if stored indoors away from direct sunlight, at temperatures not exceeding 20°C.
Multipurpose mineral fiber reinforced polyester mastic
The excellent anchorage to the substrate, the excellent spreadability and rapid and complete spreading even on large thicknesses make it a useful product on the building site both as a general assembly mastic (model framework, spot-welding of spars, fixing of bulkheads, interior fittings ) and as a putty for filling seams and starting and finishing surfaces.
Recommended: polyester fiberglass and vinylester laminates.
