Two part urethane non-sag seam sealer duplicates a factory appearance on truck bed seams, tooled door skin seams, floor pan seams, core support seams. To be used to re-create the sprayed effect. blending should be made through static mixer composed by a minimum of 16 elements. A lower number of components doesn't allow a complete mixing. A higher number of components would increase speed of the chemical reaction of hardening. Static mixer are disposable. Bi-components cartridges can be used through manual applicators or specifics pneumatic tools, depending on capacity and cartridge shape. For process and in continuative applications, automatic dosing systems for low viscosity materials can be used. Base on specific needs Inchimica's technical service is available to offer advice for the correct machinery to use with specific requirements. The mixture must be applied directly from the mixer on the pre-treated dry surface. The optimal layer of adhesive that will guarantee the highest resistance for the joint should be at least 0.5 mm thick. The components have to be assembled before the adhesive starts curing and sealed with a steady pressure all over the gluing area. The speed of the hardening reaction is mainly influenced by two factors, the application temperature and the application thickness. Being the reaction exothermic, the speed decreases as the thickness and temperature application increase. Even if in smaller measure, the substrate influences the speed of reaction. Materials with a high coefficient of thermal conductivity will tend to slow down the reaction. The maximal temperature of the reaction will be reached in 5 mm application thickness and is always lower than 30°C.
