Epoxy Coatings Dealers in Ranipet

The company is a well-known Manufacturer and Supplier of Anticorrosive Coating. The Ultra Epoxy UEM 993 Anticorrosive Coating is modified epoxy resin which can be suitably formulated with hardeners like UH930, UH950, UH941 or UH940 and applied as anti-corrosive solvent-free coatings on surfaces. The Anticorrosive Coating is ideal where protection against corrosive environment is of prime importance. To name a few field of applications, the Anticorrosive Coatings are used on steel and concrete structures in chemical plants, oil refineries, marine installation, food factories, paper mill, civil structures, bridges, dams, lock gates, canal bottoms and banks, internal and external surfaces of steel or asbestos pipes storage tanks, reaction vessels and others. The solvent-less Anticorrosive Coatings can be applied by conventional brushings and trowel ling methods. In general, two Anticorrosive Coatings are applied: the first Anticorrosive Coating being the primer coat and the second being the top coat, However, the number of coats can be increased, depending upon the degree of abuse the surface is exposed to. Information On Processing Preparation Of Surface The preparation of surface over which the Anticorrosive Coating is to be applied is of primary importance for achieving the most optimum surface for better adhesion of the coating. If the surface is metallic it can be sand blasted or roughened with emery paper. The surface must be thoroughly cleaned and should be devoid cleaning may be done with solvents like tri-choroethlyene, carbon tetra chloride, toluene etc. Incase the concrete surface is too smooth, it can be roughened by treatment with dilute hydrochloric acid and followed by thorough washing with plenty of water till the washing is neutral top litmus. The surface then may be dried before application of coating.Mixing RatioPrimer CoatUltra Epoxy UEM 993 : 100 parts by weightHardener UH 941 : 80 party by weight Or Ultra Epoxy UEM 993: 100 parts by weight Hardener UH940: 50parts by weight The Resin and the Hardener can be mixed in a container manually till homogenous state is reached. The mix then can be applied as primer coat.Top Coat In preparation of the top coat, different rate of cure may be achieved with Ultra Epoxy UEM 993/ UH930/ UH950. Typical 3 ratios are indicated below as a guideline. Depending upon the actual requirement at the time of application, suitable proportions may be used. The first 2 mixing ratios are normally being used. Apart from the resin and hardener composition, some fillers like silica flour (250 mesh) can be used. In case of the coating being applied on a vertical surface, a thixotropic agent like IF9 Can be added in the mix to the tune of 5phr and thoroughly homogenized before application.Application After the surface is prepared, the primer coat van be applied by brushing or trowel ling as may be found suitable, up to a required thickness of coat. After the primer coat is applied, it may be allowed to stand at room temperature, till such time the coating becomes tacky to tough. At this stage, the top coat may be applied by brushing or trowel ling. In case, the primer coat has gelled into a hard mass, the surface may be lightly abraded with a sand paper and then the top coat may be applied. After the coating has gelled, it will take about 7 to 8 day to room temperature to attain the full cure. Such a Coating will exhibit very strong bond on to the surface and resistance against a wide range to chemicals. The heat distortion temperature of this system is slightly above 80*c.Coverage 1 kg of the mix of the above formulations will cover approximately 2 to 3 sq.m of the surface for a thickness of about 300 to 400 microns. However, the coverage will vary depending upon the porosity and degree of roughness of the surface.
