Every can of paint is a carefully balanced formulation of pigments, binders, solvents and additives. For a coatings manufacturer, the quality and consistency of those raw materials directly determines opacity, gloss, durability and cost. This guide breaks down the core raw materials for the paint and coatings industry and how Pakistani manufacturers can secure a dependable supply.
The four building blocks of a coating
Almost every paint or coating is built from four functional groups:
- Pigments — provide colour and opacity
- Binders / resins — form the film and bind everything together
- Solvents — control viscosity and application
- Additives — fine-tune performance (drying, flow, anti-settling, matting)
Get the balance right and you have a coating that applies well, looks right and lasts. Get it wrong and you get poor hide, sagging, or early failure.
Pigments and extenders
Titanium dioxide (TiO₂) is the workhorse white pigment — the single biggest driver of opacity and cost in most paints. Alongside it, manufacturers use:
- Iron oxide pigments (red, yellow, black) for earth tones
- Organic pigments for bright, clean shades
- Chrome and chrome-yellow pigments for high-visibility and industrial colours
- Zinc phosphate as an anti-corrosive pigment in primers
- Carbon black for deep blacks and tinting
- Aluminium paste (leafing and non-leafing) for metallic finishes
- Extenders like calcined kaolin to control cost and film properties
Resins and binders
The binder defines the coating's backbone. Common choices include:
- Acrylic emulsions and styrene acrylic for water-based decorative paints
- Alkyd resins for solvent-based enamels
- Epoxy resins and hardeners for protective and floor coatings
- Chlorinated rubber and hydrocarbon resins for specific industrial and marine systems
Solvents
Solvents carry the resin and control how a coating flows and dries. Widely used grades include white spirit, mixed xylene, butyl acetate, ethyl acetate, isopropyl alcohol (IPA) and glycol ethers such as butyl glycol. Selecting the right solvent blend controls drying time, levelling and finish.
Driers and additives
The small-dose ingredients that make a formulation work:
- Driers (cobalt, calcium, zirconium, manganese, zinc) to catalyse oxidative curing in alkyds
- Cellulose ethers (HEC, HPMC) as thickeners and rheology modifiers
- Dispersing and wetting agents for stable pigment dispersion
- Defoamers and coalescing agents (e.g. Texanol)
- Fumed silica for anti-settling and thixotropy
- Matting agents to control gloss

Sourcing consistency is everything
In coatings, batch-to-batch consistency is not a luxury — a slight shift in pigment strength or resin quality shows up immediately in the finished product. That is why manufacturers value a supplier who sources from reputable, consistent manufacturers and holds stock of fast-moving materials.
Aleemsons supplies the paint, coatings and printing-ink industry across Pakistan with a comprehensive range of pigments, resins, solvents, driers and additives — as both a local stockist and an indenting agent for bulk requirements.
