Primer is the base coat that seals the surface and helps the topcoat stick. Wall primer and cement primer use water-based binders, and metal primer uses an anti-corrosive pigment. Here you will find the primer raw materials for each type.
Choosing the right raw materials for wall primer, metal primer and cement primer starts with the surface the primer will cover.
We help you choose grades and suppliers, set simple receiving checks and keep your formula stable from lot to lot. For wall, cement and metal primer raw materials, material selection and supplier guidance come from the technical team of IPCS (Indian Paints Consulting Service).
Primer Raw Materials overview
A water-based primer uses a binder emulsion, fillers and a small amount of pigment, with additives for dispersion, foam and preservation. A metal primer uses a resin plus an anti-corrosive pigment that protects the metal from rust.
Primers carry a high filler load, so fillers and dispersants matter as much as the binder.
Types of primer raw materials used in paint formulations
| Type | What it does | Where it fits |
|---|---|---|
| Binder | Seals the surface and holds the film | Acrylic or styrene acrylic emulsion for water-based; alkyd or epoxy for metal |
| Fillers | Body and sealing | Calcium carbonate, talc and clay |
| Pigment | Colour and some hiding | Titanium dioxide and iron oxide |
| Anti-corrosive pigment | Protects metal from rust | Metal primer (zinc phosphate type and similar) |
| Additives and carrier | Dispersion, foam control, preservation | Water or solvent |
Applications of Primer Raw Materials
Match each raw material group to the surface you will coat.
Choosing primer raw materials for a paint formulation
What to compare
- Raw material list for wall primer: binder, fillers, pigment, additives, water
- Anti corrosive pigment for metal primer: choose by corrosion class and resin
- Raw materials for water based primer: low-odour binders and standard additives
- Compatibility with the topcoat
- Cost per litre
Quality checks on receipt
- Receiving checks on binder, filler and pigment
- Compare with the approved sample
- Keep a lot record
Storage and handling
Store binders away from frost and sun, fillers and pigments dry, and solvents in closed earthed containers.
Frequently Asked Questions
What are the raw materials for wall primer?
A water-based binder, fillers such as calcium carbonate or talc, a little pigment, additives and water.
What are metal primer raw materials?
A resin such as alkyd or epoxy, an anti-corrosive pigment, fillers, solvent and additives.
What are cement primer ingredients?
An alkali-resistant binder emulsion, fillers, additives and water, chosen for fresh cement surfaces.
What is an anti corrosive pigment for metal primer?
A pigment that protects metal from rust, for example zinc phosphate types. Choose by the corrosion class of the job.
