Aluminium Treatment – Comprehensive Solutions for Surface Enhancement
Aluminium treatment is a crucial process for ensuring durability, corrosion resistance, and enhanced adhesion of coatings on aluminium surfaces. Our Aluminium Treatment solutions include cleaning, degreasing, etching, desmutting, and passivation, offering the best surface preparation for powder coating and anodizing applications. With high-performance products like Duraclean 100, Durapass 714 A/B, and Durachrome 1000, we provide eco-friendly, effective solutions for industrial aluminium finishing.
Aluminium Treatment for Powder Coating
Powder coating is a popular aluminium finishing process, and our Aluminium Treatment solutions ensure optimal adhesion and long-lasting performance. We offer Durapass 714 A/B, a chrome-free passivation system that creates a uniform, transparent conversion layer. This product is QUALICOAT-approved and provides superior corrosion resistance without environmental hazards.
Features of Durapass 714 A/B
- No-rinse passivation for aluminium pre-treatment lines.
- Thin, transparent, chrome-free coating.
- Eco-friendly and low-temperature application.
Chromating Solutions – Durachrome 1000
Chromating is a well-known Aluminium Treatment method, and Durachrome 1000 is designed for forming a golden yellow chrome conversion layer on aluminium and zinc alloys. This solution operates at low temperatures while offering superior corrosion protection for final finishes.
Features of Durachrome 1000
- Produces 0.6 to 1.2 g/m² laminar golden yellow coatings.
- Provides excellent adhesion and corrosion protection.
- Compatible with spray and immersion applications.
Aluminium Treatment for Anodizing
Anodizing enhances aluminium by providing a protective oxide layer. Our Duracolor series offers high-quality electrolytic coloring solutions for aluminium, ensuring long-lasting and aesthetically appealing finishes.
Duracolor 400 & 405 – Electrolytic Coloring
- Produces champagne to dark shades with precise control.
- High throwing power for uniform results.
- Operates under controlled temperature for optimal coloring.
Duracolor S & R – Stabilizers and Coloring Agents
- Duracolor S: Enhances stannous stability in the electro-coloring bath.
