Coating formula: coil coating formula

Core tip: coil coating is a kind of professional coating used for coating the surface of steel plate and aluminum plate and making pre coated coil Coil coating includes alkyd coating, amino alkyd coating, acrylic coating, oil-free polyester coating, silicone modified polyester coating, silicone modified acrylic coating and fluororesin coating, etc (1) Formulation of coil coating (sea blue) Component dosage / weight polymer dispersant 10.3 polymer mixed solvent 111.2 stability BS phthalocyanine blue 12.0 golden red or titanium dioxide 60.0 oil-free polyester resin (60%) Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating home news: coil coating is used for coating steel plate, aluminum plate surface, made of pre coated coil after the use of a professional coating Coil coating includes alkyd coating, amino alkyd coating, acrylic coating, oil-free polyester coating, silicone modified polyester coating, silicone modified acrylic coating and fluororesin coating, etc (1) Formulation of coil coating (Navy Blue) component dosage / mass fraction polymer dispersant 10.3 polymer mixed solvent 111.2 stability BS phthalocyanine blue 12.0 golden red or titanium dioxide 60.0 oil-free polyester resin (60%) 120.0 all methyl ether amino resin (98%) 18.4 cooling catalyst (2.5%) 0.7 leveling agent 0.8 defoamer 0.4 fumed silica extinction powder 15.0-20.0, the high boiling point mixed solvent is s-150, the high boiling point mixed binary ester and propylene glycol methyl ether (2) Configuration of coil coating Add phthalocyanine blue and titanium dioxide powder into the high boiling point mixed solvent with high polymer dispersant for 5 minutes, and then add oil-free polyester resin, all methyl etherified amino resin, cooling catalyst, leveling agent, defoamer and other auxiliaries, mix and disperse for 10 minutes, and pass the sanding mill until the fineness is qualified Add the extinction powder in proportion according to the extinction effect, high-speed dispersion is uniform and fineness is close Filter after grid (3) All the cross-linking reactions of catalyst and its amount of amino resin are enzyme catalyzed reactions P-toluenesulfonic acid or its esters and salts are effective catalysts for this kind of amino resins When the effective catalyst of oil-free polyester resin is 4:1 with all methylated amino resin, 1% catalyst is suitable (4) Amino resin is often used as crosslinking agent in coil coating The amino resin with high etherification and low molecular weight was selected Generally, the effective catalyst of oil-free polyester resin is suitable for 4:1 total methylated amino resin (5) The dispersant and its amount of oil-free polyester and polymer dispersant are 9:1 Inorganic pigment and dispersant are generally added according to 10% of oil absorption; for organic pigment, dispersant is generally added according to 20% of dibutyl phthalate absorption (6) The choice of pigment white pigment can be rutile titanium dioxide Stable phthalocyanine blue, phthalocyanine green, diazo macromolecular r red, diazo yellow pigment and anthracene red are selected as color pigments Fumed silica was used as a matting agent (7) Leveling agent and viscosity adjustment leveling agent of high boiling point solvent dme-1 can solve the phenomenon of floating color and blooming of polychrome paint at the same time The viscosity of the coating should be 80-150s (coating - 4 cups) (the paint formula in this paper is for reference only) paint home is focused on the news and information of coating, diatom mud, paint coating, coating process, fire retardant coating, and coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
