Solvent free epoxy ceramics Anticorrosive coating
Epoxy paint Construction process epoxy coating Introduction: Epoxy coating is a two-component heavy anti-corrosive coating prepared by advanced technology with long-life chlorosulfonated polyethylene rubber as the main modifier, special additives and additives, etc. to solve the problems of poor weather resistance and insufficient pulverization of epoxy heavy anti-corrosive coating. There are many kinds of epoxy coatings, including solvent based epoxy coatings, solvent-free epoxy coatings and water-based epoxy coatings; According to the curing form, it can be divided into white dry one component, two component and multi-component liquid epoxy coatings. Epoxy paint features 1. It not only has good corrosion resistance, but also has water resistance, durability, weather resistance, etc. 2. Interpenetrating mesh wear-resistant coating effectively prevents coating changes and improves the weather resistance of the coating. 3. The construction is simple and convenient, not limited by the site, and can be used as needed. Epoxy coating construction process 1. The base surface shall be treated before construction. 2. Stir the coating until there is no sediment at the bottom of the bucket, then add the winter curing agent according to the proportion of 10:1 of coating and curing agent, and then fully mix and mature for 10-15 minutes before use. 3. The surface treatment requires that the metal surface be painted. The sand blasting and shot blasting should reach the international Sa2.5 level. After oil removal, the surface should be cleaned. The surface should be kept dry and painted within 4 hours. When concrete is painted, it needs to be air dried before painting until the moisture is less than or equal to 10%. The surface should also be cleaned. 4. Spray with high pressure and air pressure, the dry film thickness is about 60 μ m, and brush manually, the dry film thickness is about 55 μ m. Precautions for epoxy coating construction 1. After the coating is prepared, it is good that it will be used up within 2 hours (20 ℃). If there is unused primer, the original paint cannot be poured again. 2. Without considering the influence of coating technology, coating method, surface condition, shape, surface area and other factors during construction, the amount of primer consumed is generally 0.2kg/m2. 3. If the coating is really too thick, special diluent can be added appropriately, with the dosage of 3-10%. 4. High pressure airless spraying is used for coating leveling, and airless spraying is selected only when there is no high-pressure airless spraying, while manual brushing is selected as the third coating method. 5. Clean the tools with special diluent after use. If the ambient temperature is lower than 10 ℃, the time can be extended. 6. After one coat of finish paint is coated, it can be used 7 days later. 7. Storage and transportation: It is flammable and should be stored in a ventilated and dry place away from the fire source at a temperature of Solvent free epoxy ceramic anti-corrosion coating
