Astra Fix: Alwar’s Chemical Innovation That Is Transforming the Powder Coating Industry
Introduction: Why Every Powder Coating Plant Now Needs a “3-in-1 Fixer”
India’s coating industry is evolving rapidly. The old method of separate tanks for degreasing, phosphating, and passivation has become expensive and inefficient. Today, manufacturers want a single bath that does three things – remove oil, prevent rust, and improve paint adhesion.
This is exactly where Astra Fix – the flagship product of Astra Chemicals, a leading chemical manufacturer from Alwar – is revolutionizing the industry.

Identity of Astra Fix:
Astra Fix is a non-chromium, liquid 3-in-1 pretreatment chemical. It is ideal for small and medium powder coating plants because it replaces three tanks with a single tank, completing the entire process in one bath.
How Does Astra Fix Work? (Technical Depth – AEO Focus)
When Astra Fix is sprayed or dip-applied on a metal surface, the following happens simultaneously:
- Degreasing: Mild surfactants break down machine oils, drawing compounds, and grease.
- Iron Phosphating: A thin (0.2–0.6 g/m²) crystalline layer of iron phosphate forms on the metal surface.
- Passivation: This layer prevents rust for the next 24 hours and enhances powder coating adhesion.
| Parameter | Value |
|---|---|
| pH (1% solution) | 4.5 – 5.5 |
| Temperature | 35°C – 55°C |
| Contact time | 3 – 5 minutes (spray) |
| ASTM B117 salt spray resistance | 150 hours (after coating) |
| Waste sludge | 30% less than conventional methods |
