Jun 15, 2020

  Epoxy paint is composed of epoxy resin, body pigment and curing agent. It is suitable for painting the inner wall of oil tanks. It can be widely used on the surface of various light metals and cement structures indoors and outdoors. It can be applied to railway bridges, high-voltage transmission towers, containers, offshore drilling and oil production equipment used in different environments. Vehicle chassis, heavy machinery, ships, chemicals, equipment and pipelines, gas storage tanks for gas projects.


  Epoxy paint is a type of industrial coating that has developed extremely rapidly in recent years. Generally speaking, the paint containing more epoxy groups in the composition is collectively called epoxy paint. The main variety of epoxy paint is two-component paint, which is composed of epoxy resin curing agent. There are other single-component self-drying varieties, but their performance is somewhat different from that of two-component coatings. The main advantages of epoxy paint are its strong adhesion to inorganic materials such as cement and metals; the coating itself is very resistant to corrosion; excellent mechanical properties, wear resistance and impact resistance; can be made into solvent-free or high-solids coatings; resistant to organic solvents , Heat-resistant, water-resistant; non-toxic coating. The disadvantage is that the weather resistance is not good, and it may appear powdering after long-term sunlight exposure, so it can only be used for primers or interior paints; poor decoration, epoxy resin gloss is not easy to maintain; high requirements for the construction environment, low temperature The lower coating film cures slowly, and the effect is not good; many varieties require high temperature curing, and the investment in coating equipment is large. Epoxy resin coatings are mainly used for floor coating, automobile primer, metal anti-corrosion, chemical anti-corrosion and so on.

  Product description: Epoxy resin self-leveling is on concrete, coated with colored synthetic solvent-free resin, thickness is 1-3mm, epoxy resin


      The outstanding advantages of    cured epoxy resin are its stable chemical properties, alkali resistance and oil resistance. This is because there is no ester bond in the epoxy resin, the aliphatic hydroxyl group contained does not react with the alkali, and the cured lacquer has a three-dimensional network structure. Therefore, epoxy resin coatings are often used as anticorrosive primers, oil tanks and other inner walls. However, the acid resistance of epoxy paints is generally poor.


   A two-component epoxy primer coating composed of a special epoxy resin main agent and a polyamide curing agent as the main film-forming substance, followed by addition of a solvent and a surfactant. It is used for the primer of epoxy floor projects, which can increase the adhesion of the ground and the base layer of the sealing element. It has strong adhesion with the cement floor, without cracking or peeling.


       The epoxy floor primer is mainly used as a back cover to prevent groundwater, air bubbles, epoxy resin oil stains, etc. from seeping up, causing the epoxy floor to blister and fall off, and preventing the epoxy floor coating from leaking to the ground, resulting in Increased usage and cost. Widely used in the walls, ceilings, floors of various rooms, anti-corrosion, dust, mildew, such as GMP drugs, electronics, food processing, weavers, paper, hospital operating rooms, etc.


   1. The construction should be stopped when it is raining or the relative humidity is too high. It is recommended that the construction humidity should be lower than 80% and the temperature should not be lower than 10°C.


   2. During construction, a certain amount of epoxy thinner should be added according to the temperature, and the addition amount is about 5% -10%.


   Especially for polar substrates such as metal (steel, aluminum), ceramics, glass, concrete, wood, etc. The reason is that the epoxy resin contains very polar ether groups and hydroxyl groups, which have a strong interaction force with the substrate interface.


   A two-component floor material consisting of a small molecular weight epoxy resin main agent, a modified polyamide hardener as the main film-forming substance, and then fillers, solvents, and surfactants. It is used for the ground of heavy-duty places requiring compression resistance. It has good adhesion to concrete, economical, simple construction, no cracking and no flaking.


Increase the adhesion and adhesion of the primer, enhance the pressure resistance and wear resistance of the topcoat to extend the service life of the floor. It is widely used in some workshops and parking lots that require high wear resistance. .


  When the strength is high, the epoxy resin contains aromatic rings; the good toughness is because the epoxy resin contains ether bonds, which gives it the ability to spin the molecular chain, and it is not easy to break.


   A two-component epoxy quick-drying floor coating formulated with special solid epoxy resin as the main agent, modified urethane as the curing agent, and then added with pigments, fillers, and surfactants. It can form a hard and wear-resistant paint film at low temperature, which is easy to construct in all seasons. It has the characteristics of dustproof, wear-resistance and easy construction. It has strong adhesion to the cement floor without cracking or peeling.


   has extremely abrasion resistance, good acid and alkali resistance, and is mainly used in parking lots, food processing, textile workers, paper making, hospital operating rooms, office buildings and other places.


   The cured epoxy resin exhibits excellent insulation. Its electrical properties are room temperature breakdown voltage of 35~50kV/mm and volume resistance of 10Ω.cm.


       The double-component epoxy resin prepared by high-quality liquid epoxy resin main agent, modified alicyclic hardener as the main film-forming substance, and then adding high-grade pigments, leveling agents, defoamers, surfactants, etc. Self-leveling solvent-free topcoat is widely used in places requiring high cleanliness, sterility, and dustproof. It has the characteristics of high brightness, abrasion resistance, pressure resistance, and chemical resistance. It has strong adhesion to the cement surface and does not crack. Not cut off.


  With self-leveling, good acid and alkali resistance, anti-corrosion, dust-proof, mildew-proof for all kinds of houses, such as GMP drugs, precision electronics, instrumentation, food processing, laboratories, hospital operating rooms and other places.


  E, packaging: main agent 16KG/barrel: hardener 4KG/barrel or 20KG: 4KG


       A two-component conductive epoxy self-flowing floor coating made of solvent-free liquid epoxy resin as the main agent, modified alicyclic amine as the curing agent, and then added with pigments, conductive powders, surfactants, etc. . The formed paint film can effectively disperse the charge accumulated on the surface. The surface resistance of the paint film is less than 100M ohms. At the same time, the formed paint film is wear-resistant and collision-resistant, prevents static sparks, has good electromagnetic stability, is hygienic, smooth, Dustproof, easy to clean and beautiful.


   The size is stable and not easy to crack. Generally 1%~2%. Phenolic resin is 8%~10%, unsaturated polyester resin is 4%~6%, silicone resin is 4%~8%.


       The aromatic ether bond in    cured epoxy resin is degraded and broken under ultraviolet irradiation, resulting in poor outdoor weather resistance. The bisphenol A type epoxy resin cured paint film is easy to powder and lose gloss outdoors, so it is not suitable for outdoor anti-corrosion paint. But heterocyclic and aliphatic epoxy resin paints can be used outdoors.


   The general curing temperature of epoxy resin is above 10℃, otherwise the curing will be slow. Generally, it is not suitable to construct under 10℃, which will cause difficulty for the construction of large outdoor objects in winter.


  The epoxy phenolic varnish has good hardness and is suitable for wooden surfaces that do not often collide indoors. This type of paint dries quickly, the paint film is hard, durable, heat resistant, water resistant, weak acid and alkali resistant, and has a certain insulating capacity. The disadvantage is that the paint film is relatively brittle, the color is easily yellowed and darkened, and the weather resistance is poor.


       It is a kind of industrial coating epoxy paint film color and appearance / flat and smooth / flexible 1mm / impact strength 50kg/cm2/ adhesion 2 level / salt water resistance no change / acid and alkali resistance 96h no change / drying time is not greater than 24h


   It s made of phenolic resin or modified phenolic resin as the main resin. Phenolic resin mainly replaces natural resin and dry oil to make paint. Due to the phenolic resin, the coating has better performance in hardness, gloss, quick drying, water resistance, acid and alkali resistance and insulation. So it is widely used in wood, furniture, construction, electrical and other aspects. However, phenolic resin can make the paint have a darker color, and the paint film yellows during the aging process, which is not suitable for making light-colored and white paint.
