Coil Coating

Coil coating is a continuous and highly automated process for coating metal before fabrication. In one continuous process both the top and bottom sides are cleaned, chemically treated, primed, oven cured, top coated, oven cured again, rewound and packaged.

Coil coating provides beautiful topcoats, durable surfaces, innovative applications, green benefits, and cost savings as compared to other substrates and other coating options. Coating systems supplied as per the specification consist of a Primer coat covered by various types and thicknesses of top coats. The combination of primer and top coat is classed as either a two-coat thin- film system or as a multi-coat (two or more) thick-film system.

Coil coatings comprise liquid paint in a wide range of colours and finishes that can be applied to continuous steel or aluminium strip. These can be cured in seconds and recoiled for delivery to end users. The coil coating process not only creates new markets for sheet metal products, but also reduces the environmental impact by minimizing paint waste and making use of excess solvents. Evaporating solvents are incinerated to generate heat for curing ovens, thus preventing waste and pollution.

PAINT TYPES AND SPECIFICATIONS

R.M.P (REGULAR MODIFIED POLYESTER)

Regular Modified Polyester is most widely-used coating with durable Polyester paint and heat dried. It is applied to interior/exterior materials with no heavy drawings. RMP coated products are used for exterior panels and interior design purposes that do not require excessive processing. It generally displays superior workability, durability and weather resistance and used for a variety of purposes; offered in a wide array of colors and degrees of polish. Matt and wrinkle effect can be added to the top finish.

END USAGE:

Roofing & siding panels Interior Partition Building Interior/Exterior Sandwich panels Roof, Gutter Steel furniture Shutter, Door, Garage Door, Iron Frame, etc.

S.M.P (SILICON MODIFIED POLYESTER)

Silicon Modified Polyester is a silicon resin modified Polyester paint coated and heat dried. Due to its higher durability than the Regular Polyester, generally applied for building construction. SMP assures economic benefits under circumstances of sea-side or industrial zones.

END USAGE:

Public Construction Material, Sandwich Panel, Corrugated Roof in Industrial Complexes, Airport, etc.

H.D.P (HIGH DURABLE POLYESTER)

High Durable Polyester is high weather-proof resin is developed with Hydrogenated monomer & Neo structure monomer. Assures similar durability as PVDF, but with more competitive price and advantages of various colors & gloss. Can be coated into a various pattern, inspired by customers' needs.

END USAGE:

Metal Exterior, Plant, Roof, Gutter, Roof, Industrial Building, etc.

P.V.D.F (POLY VINYLIDENE FLUORIDE)

Poly Vinylidene Fluoride coating assures high weatherproof against climate and durability, wear resistance & machinability. With PVDF unique painting technique, can be made into a simple mono color type (Solid/Metal/Mica) as well as in various pattern types. PVDF (fluorine-carbon) coating made of fluorine carbon resin, pigment, ester solvent, after high temperature roasting and baking, the paint is solidified to dry film with super weather resistance. The hydrophilic surface treatment will prevent dusts adhesion on the surface and enable dust to be removed easily. PVDF coatings are especially resistant to solvents, acids and heat and has low density compared to similar fluoropolymers.20 years of limited warranty provided depending on the regions.

END USAGE:

Roofing or building industry (Cladding, Rolling Shutter, Facades, Interior ceilings) Defense industry Medical industry Semiconductor industry Fishing industry

PLASTISOL

Vinyl plastisols are dispersion of special, fine particle size PVC resins in plasticizing liquids. These materials are liquid at room temperature, but as the compound is heated in the finish oven, fusion takes place and the liquid is converted into a tough, homogeneous mass. The benefits of plastisol coil coating are numerous. Plastisol coil coating can add color, cushion, texture, safety, and quiet to the surface of your product or part, while simultaneously resisting abrasion, corrosion and electricity. Heat or light stabilizers, flame retardants, bonding agents and other additives are available to meet a variety of specifications including Automotive and Military applications. Plastisol coating can offer properties such as non-slip, cushioning, color coding, electrical insulation, abrasion resistance, impact resistance, weather and corrosion resistance. Plastisol coating up to 200 Microns with smooth or Leather finish on Aluminum or GI Steel has been used to cater the needs of cold storage and food processing markets.
