Coating Technology

Our expertise lies in offering our customers a wide range of latest coating technology based Coating solutions. Backed by well developed facilities, we can offer CED Coating services as per the specific application demands of our customers including offering solutions in customized finishes. The details of services offered by us include:

CED Coating

CED Coating

For successfully maintaining best quality E- coat results, we use PPG paint under control of PPG guidelines & supervision of PPG personnel. The exclusive process followed by us at our end include Stage 1 - Manual cleaning by solvent for dust & excess oil removals, Stage 2 - loading for auto line process and Stage 3 - Degreasing chemical -non-caustic alkaline cleaner compound chemical with operating temperatures of 20ºC t0 30º C (It is suitable for mild steel brass aluminium, copper & steel also and apply cleaner to remove light surface oxides and any remaining lubricants).

The other stages include:

 

Stage 4

Running water rinsing ambient operating temperature (This stage removes soils loosened by cleaner and removing cleaner residue)

Stage 5

De-ionized Rinse Conditioner -DI Rinse Conditioner with ambient operating temperature (This stage prepares cast/metal surface to accept Hazard free non phosphate coating)

Stage 6

User friendly, environment friendly, hazard free non phosphate coating that is multi metal system based. Here the chromium 3 generation produces uniform, compact nano size base coating for delivering excellent corrosion resistance & adhesion protective coating free of phosphates, zinc, nickel, nitrates, manganese & VOC with RoHS (EU Directive 2002/95/EC) & WEEE (EU Directive 2002/96/EC) & ELV compliance (Continuous chemical movements & spray for 02 solubility in chemicals available here)

Stage 7

Ultraviolet water treated De ionized Rinse that have ambient operating temperature (This stage removes salts & stops coating reaction as well as lowers surface conductivity of part to prepare it for e-coating)



Electrocoating

Electrocoating

We offer our customers electro coating service that is also referred to as electro deposition/ electro-phoretic deposition or electro painting. Further, Electro coating resembles electroplating in that it utilizes electrical current for depositing coating onto substrates. However, electro coating deposits water born paints onto substrates rather than on metal ions.

The overall process undertaken comprises of four main process steps:

  • Pre-treating
  • Electro coating
  • Rinsing
  • Baking
Electro coating Process:
  • It may be anodic/cathodic, depending on charge applied to the substrate
  • Although processes are virtually same, properties of resultant coating are dissimilar
  • Anodic systems that were first to be used for electro coating apply paints to positively charged substrates where the negatively charged pigments & resin particles deposit onto substrate (anode) (One disadvantage of the process is that substrate metals dissolve & become incorporated into coating that affects surface properties)
  • Cathodic electro coating deposits paint onto negatively charged substrates & offers several advantages over anodic electro coating including metal dissolution of substrate does not occurring on cathodic electro coating as it has ability to deposit over contaminants (It also improves corrosion resistance as well as in achieving better color consistency over welded areas)


The electro coating process is divided into four distinct steps:

  • Pre-treatment
  • Electro coat bath
  • Post rinses
  • Baking

Pre-treatment – Cleaning and phosphating the metal –

  • Pre-treatment zone cleans & phosphates metal to prepare surface for electro coating
  • Cleaning & phosphating are essential to achieve performance requirements desired by today’s end user of products
  • A high quality zinc phosphate system using immersion method is primarily used where steel & iron parts are coated

Electro coat bath – Applying coating in bath –

  • Electro coat bath & ancillary equipment zone is where coating is applied & process control equipment operates
  • The electro coat bath consists of 80-90% de-ionized water & 10-20% paint solids
  • Here, the de-ionized water acts as carrier for paint solids that are under constant agitation (The solids consist of resin and pigment)

Post Rinses - Rinsing off excess paint solids –

  • The post rinses provide both quality & conservation where during electro coat process, paint is applied to part at certain film thickness (regulated by amount of voltage applied)
  • Once coating reaches desired film thickness, part insulates & coating process slows down
  • As part exits bath, paint solids cling to surfaces and need to be rinsed off to maintain efficiency & aesthetics
  • Excess paint solids are called “drag out” or “cream coat ”and these excess paint solids are returned to tank to create coating application efficiency above 95%

Bake oven – Thermally curing the paint films –Bake oven receives parts after they exit post rinses

  • The bake oven cross links & cures paint film to assure maximum performance properties
  • Here, the minimum bake schedule is 20 minutes with part temperature at 375°f for most electro coat technologies
  • However, there is also “low temperature cure” electro coat material where the material has minimum cure of 20 minutes at part temperature of 180°f (This allows many assemblies containing seals, bushings, bearings or oil to use electro coat process)

ED Coating

ED Coating

We offer our customers’ed coating that helps in providing tough, durable as well as lasting coating for metals. It also helps in providing excellent hardness & abrasion/impact resistance that gives improved product performance over most liquid coatings. Further, these are offered in a wide range of color options.

Features:


  • Environmentally friendly outsourcing option for avoiding permitting for solvent-based paints
  • Less process variation that results in consistent color & appearance of products
  • High film builds & excellent edge coverage that gives better resistance to corrosion with proper pre-treatment
  • Coatings can be easily formulated for specific applications like prolonged exposure to sunlight, the ability to survive in highly corrosive environments as well as flexibility to allow forming after coating/ high durability as well as resistance to chipping

Typical ED  Coatings Available:

Epoxy –

  • Excellent corrosion resistance
  • Superior toughness, adhesion and hardness
  • Poor weather-ability
  • Can be formulated to be FDA compliant for food contact applications
  • Decorative or functional coatings available

Epoxy/Polyester Hybrid –

  • Less susceptible to yellowing when cured
  • Exhibits similar properties to standard epoxy coatings
  • Poor weather-ability makes this unsuitable for outdoor use

Polyester/Urethane –

  • Smooth, thin film with excellent mar & chip resistance and good weather-ability
  • These coatings are generally resistant to diluted acids, hydrocarbons as well as grease and oil

Polyester/TGIC –

  • Excellent weather-ability with excellent mar, chip as well as corrosion resistance
  • Excellent edge coverage

“EnC”s Capabilities:

  • Two automated powder coating lines
  • Decorative & functional coatings
  • High temperature coatings
  • Manual & automatic coating systems
  • Long/short runs in any color
  • Coatings available in standard/metallic, high gloss to low gloss, smooth, textured/wrinkled
  • 7-stage phosphate in-line immersion pre-treatment system with laser scale removal capabilities
  • Part sizes up to 5 feet long
