#self-etching primer

Etch Primers protects the metal from flash rust due to oxidation, but also prepares the surface for the final paint coat. The primer itself contains the operative elements acid and zinc. In the list of top manufacturers and suppliers of all kinds of thinners, coatings & paints in India, Zigma Paints (P) Ltd. has carved out a name for itself. We are ranked among reliable manufacturer, distributor and supplier of pure quality Etch Primer paints in Nashik, India.

Etch Primers are single-pack metal primers designed to optimize adhesion to the different metal surfaces on which they can be used, using a mixture of resins. A low level of phosphoric acid is present in these primers to etch the metal surface and improve adhesion. To meet the ever-changing demands of our valued customers, we are bringing forth the promised quality 0271 Zigmalac® 2K etch primer.

Etch Primers: Uses & Application areas

Used in various industries & various commercial sectors.

Used to adhere to the different metal surfaces of machinery.

Etch primers used for storage Tanks, Ships, Airplanes, Bridges, Damb locks, Agricultural equipment's.

It is also applied in all cases where paint coating require weathering, seawater resistance

 Advantages:

Excellent water and alkali resistance.

Resistance to mild acids.

Excellent weather and water resistance.

Very good resistance to solvents.

Adhesion to many substrates.

Fibreglass sheets, Aluminium, Steel, and M.S

Any type of topcoat is suitable.

Unaffected by Oil & Grease.

Fast drying

For those parts, for parts repainted with enamel-based paints, the etching-primer is applied immediately after the metal part has removed the old paint and dirt. Not only does this shield the metal from flash corrosion due to oxidation, but the surface is often primed for the final coat of paint.

Self-etching primers are capable of doing anything that is difficult for standard primers. It contains an acidic chemical that bonds, or etches, onto a metallic surface. Etching readies metal for a topcoat. The etching creates a rougher surface for the topcoat to cling to, much like sanding would accomplish.

How to Apply Self-Etching Primer

Applying a self-etching primer, for the most part, is like applying a standard primer. Clean and smooth surfaces include both. According to the product’s manual, below is the best method for using a self-etching primer.

Before starting any project, check for any damage that can be easily repaired. It's a handy self-etching primer, but it can't patch fiberglass cracks. Rust should also be sanded off beforehand.

Ensure surface is clean from grease and oils

Let dry completely

Shake can well

Keep can 12-16” from surface

Spray in a back-and-forth motion

Let dry completely

Smooth any bumps or rides with sandpaper

They are also known metal primers composed with a combination of resins to maximise adhesion to the various metal surfaces on which they may be used. A low level of phosphoric acid is present in these primers to etch the metal surface and improve adhesion. It is also known as WASH PRIMER and referred to as metal conditioners. For all types of metal that need a very fast turn-around time, etch primers are convenient for priming. In order to etch the metal surface and create a tenacious bond, they only need a very thin coat. Any degree of corrosion safety is provided by zinc phosphate pigment. The quick dry features allow the topcoat to be applied shortly after application of the primer. In low corrosivity conditions, thin film restricts the application of metals and is not ideal for heavy duty, high film intermediates and topcoats.
