Zinc Rich Primer Powder coating Manufacturers in Chennai
Zinc Rich Primer powder coating manufacturer in Chennai – Sri Lakshmi industrial coatings is the wide range of quality Zinc rich primer powder coats an experience and expertise to deliver an optimum blend of quality, service, and price. We can be controlled by providing a barrier against the passage of ions, oxygen and water. Our products on the environment while simultaneously delivering business value to our customers.
The lower the permeability of the coating for these species, the better the barrier properties. It is important to realize that a barrier coating cannot repair corrosion products or other surface impurities already present on the metal surface.
For corrshield properties, these coatings use a new pure epoxy system technology. They either reduce or eliminate the pre-treatment necessity.
It is zinc rich epoxy based on thermosetting powder coating designed to enhance the Rust resistance of steel items. It has been designed as a base coat for powder top coats.
Zinc Primer has a multitude of users over steel objects. If chemical treatment is difficult, a zinc base powder primer provides the solution on shot blasted steel.
Rusting starts when the coating is damaged, the underlying metal could be exposed and the presence of water and aggressive species induces the onset of corrosion.Corrosion is defined as an electrochemical deterioration of a metal due to the reaction with its environment involving the oxidation of a metal.
- The local atmosphere and special stresses of the structure greatly affect the durability of corrosion.
- Zinc-rich epoxy paint is designed as a primer in coating systems where excellent durability is needed.
- They provide good corrosion resistance by cathodic protection. Zinc dust will sacrifice itself and protect the steel substrate which becomes the cathode.
Zinc Phosphate Primers are steel primers formulated with zinc phosphate, a mineral that offers inhibitive or active corrosion protection to protect the steel substrate from corrosion. They act differently from other forms of corrosion protection.

FAQ’s of Powder Coating Services
What is a zinc rich primer?
Zinc rich primers primarily contain a high concentration of zinc dust. This coating agent acts sacrificially when in direct contact with the steel forming zinc salts. The zinc salts then effectively fill the pores of the primer sealing off the steel substrate from moisture.
What Colour is zinc rich primer?
Cromadex 750 Two Pack Epoxy Primer
It contains zinc phosphate giving added corrosion resistance for greater durability. The product can be air dried or stoved giving flexibility in production. It is available in white and grey as standard, it can also be tinted to ensure…
Why use zinc rich paint?
Zinc rich paints are primarily used to protect metallic surfaces from corrosion by providing cathodic protection at the expense of the zinc contained in these paints.
Is zinc primer any good?
Zinc-rich primers, and all galvanic systems, are perfect primers for steel assets in highly corrosive environments.
What are the different types of zinc rich primers?
There are two types of zinc primers: organic and inorganic. Organic zinc rich primers are often used in the form of a moisture cured urethane zinc primer.
How do you remove zinc primer?
Removal usually entails using a non-metal bristle brush with a weak acid such as vinegar. If there is any significant loss of the zinc coating after the white rust removal, recoating may be required to achieve the minimum film thickness.
How much zinc is in zinc rich primer?
Rust-O-Zinc contains up to 86% zinc in the dried film.
Is there a primer without zinc?
Corro Guard Primer is a heavy-duty water-based epoxy primer that can be used on metal or concrete where maximum long-term protection is desired. It’s a zinc-free, chip-resistant formula with an improved shelf life.
