It provides a structured summary of Astra Chemicals and the Zirca■Sil zirconium■based surface
pretreatment technology.
1. Company Overview — Astra Chemicals
Astra Chemicals supplies industrial surface treatment and metal finishing chemistry. Its product
portfolio includes pretreatment chemicals, phosphating alternatives, aluminium surface treatment
solutions, cleaners and support chemicals for coating lines. The company’s solutions are designed
to enhance coating adhesion, corrosion resistance and process reliability across a wide range of
manufacturing industries.
2. Zirca■Sil Technology Overview
Zirca■Sil is a zirconium■based nano■conversion coating technology described in the referenced
brochure. It serves as an alternative to conventional iron and zinc phosphating systems. The
process forms an ultra■thin and uniform nano■film coating layer — typically in the range of
approximately 40–80 nm — which improves paint adhesion and corrosion performance prior to
powder coating or liquid painting.
3. Key Features & Benefits
Feature Benefit
Nano■thin uniform coating Improved surface bonding and coating adhesion
Phosphate■free / low■phosphate chemistry Environment■friendly with reduced sludge generation
Applicable via spray or immersion Easily adaptable to existing pretreatment lines
Lower process waste & maintenance Reduced operating and disposal cost
Supports multi■metal compatibility Suitable for aluminium and general metal finishing
4. Typical Industrial Applications
Zirca■Sil pretreatment is typically used in aluminium powder coating plants, fabricated sheet metal,
automotive components, industrial equipment, architectural aluminium profiles and other coating
lines where enhanced coating performance, sustainability and long■term corrosion protection are
required.
