Coating classification: water based glass baking paint

Core tip: brief introduction: the water-based glass baking paint is a kind of water-based paint which is made of water-based acrylic acid resin, water-based amino resin, organic pigment, auxiliaries and cosolvent by high-speed dispersion, grinding and modulation The water-based glass baking paint uses clear water as diluent, does not contain harmful solvent, will not cause environmental pollution before and after construction, and will not harm human health The VOC content discharged is better than the requirements of environmental standards, and the performance indexes of the product are better than that of the solvent based similar paint The water-based glass baking paint is not easy to burn, is non-toxic and odorless, and meets the requirements of the characteristics of environmental protection paint It is a new environmental protection paint product Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: brief introduction: the water-based glass baking paint is a kind of water-based coating which is made of water-based acrylic resin, water-based amino resin, organic pigment, auxiliary agent and cosolvent through high-speed dispersion, grinding and preparation The water-based glass baking paint uses clear water as diluent, does not contain harmful solvent, will not cause environmental pollution before and after construction, and will not harm human health The VOC content discharged is better than the requirements of environmental standards, and the performance indexes of the product are better than that of the solvent based similar paint The water-based glass baking paint is not easy to burn, non-toxic and odorless, which meets the requirements of the characteristics of environmental protection paint, and is a new environmental protection paint product Technical indicators: the technical indicators of water-based glass baking paint are shown in the following table: technical indicators of the project coating appearance varnish: clear, transparent, flat, smooth and high-color paint: flat, bright and glossy (60 °) ≥ 85% drying conditions 170-180 ℃ / 20 min pencil hardness (Zhonghua brand) ≥ 3H adhesion (grid method) ≤ level 1 flexibility ≤ 1 mm impact test 50 kg / cm Water resistance (soaking in distilled water for 480 h) does not blister, with slight change allowed It can recover from water boiling test (running water at 100 ℃ / 1 h) does not blister, does not lose light The paint film recovers from alkali resistance (soaking in 5% NaOH solution for 48 h) does not blister, does not wrinkle, does not seep color, does not lose light and acid resistance (soaking in 5% HCl solution for 48 h) does not blister, does not wrinkle, does not seep color, does not lose light Salt spray resistance test (72 h neutral salt spray test) the part 3 mm away from the scratch side shall be free from blistering, paint falling, coating softening and corrosion products solvent resistance (cyclohexanone solvent soaking for 15 h) shall not bite, lose light, wrinkle and be restorable: ① before coating, the surface of the work piece must be cleaned to strictly avoid organic solvent, oil, acid, alkali, salt and Mechanical impurities adsorb on the surface, affecting the effect of paint film The workpiece can be derusted by sandpaper or acid pickling After surface treatment, it is recommended to apply the coating immediately to avoid flash rust; ② after opening the tank, mix it evenly and then pour it into the mixing tank, clean the residual paint at the bottom of the tank with pure water, non-ionic water or tap water, and then pour it into the mixing tank The coating product can be diluted directly with water, the dilution ratio is the weight of the coating product and the water weight ratio (1:0.2-0.4), and the spraying or dip coating construction viscosity can be adjusted according to the size of the spraying or dip coating workpiece surface angle After diluting with water, stir evenly and stand for 5min, and then test the viscosity The smaller the surface angle of the workpiece, the higher the viscosity requirement of spraying or dip coating The normal requirement is 15-28s (coating-4 cups, 25 ℃), after filtering with 200-300 mesh filter screen, it can directly spray or dip coating; ③ the metal workpiece after spraying or dip coating needs to stand and level 5-10 Min, it can be put into the oven (room) for baking The baking temperature and time are 170 ℃ - 180 ℃ / 20 min the thicker the workpiece is, the longer the baking time is The specific time is controlled by the construction situation, and the paint film must be fully cured If the dip coating method is used for construction, a dip coating groove and a spare groove shall be provided according to the shape and size of the workpiece The standby tank is mainly used for the recovery and filtration of the remaining working liquid after dip coating, and the working liquid after treatment can be recycled The workpieces can be placed in the oven (room) for baking after being immersed and leveled, and the baking temperature is 160 ℃ - 180 ℃ or adjusted according to the requirements of workpieces during construction The film must be fully cured Scope of application: water-based glass baking paint is mainly used for plane glass, furniture glass, lighting glass, toughened glass, Christmas crafts glass, wine bottles, cosmetics glass and other glass products Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
