Patta Self Drilling Screws

Product Description

Patta Self Drilling Screws

PATTA Self Drilling Screws comes in both Zinc as well as Ruspert® Coating (Anti-Corrosive).

Ruspert® metal finish is a non-organic, high grade metal surface processing technology that prevents corrosion. It consists of three layers: the first layer; a metallic zinc layer, the second; a high grade anticorrosion chemical conversion film, and a third outer layer; baked ceramic surface coating.

The distinguishing feature of Ruspert® is the tight joining of the baked ceramic surface coating and the chemical conversion film. These layers are bonded together through chemical reactions, and this unique method of combining layers results in a rigid combination of the coating films. Ruspert® treatment does not attribute its anti-corrosion properties to merely a single material, but the synergy of these three layers, which combined have superb rustproof qualities. Compatible with metal coated and painted surfaces, fasteners coated with Ruspert® are resistant to acid and alkaline attack, galvanic corrosion and hydrogen embrittlement. These fasteners conform to corrosive gas test standard (Kesternich) DIN50018 SFW-0.25 and give a Salt Spray Fog Test to exceed (JISZ2731) 504 Hours.

Features:

• Superior corrosion resistance. Excellent against gas, weathering and other kinds of corrosive factors including Salt Water.
• Resistant to Acid and Alkaline Attack, Galvanic Corrosion and Hydrogen Embrittlement.
• Corrosion resistance against scratches. Composite layers minimise the effect of scratches on the protection coating.
• Electrolytic corrosion resistance. Less contact corrosion with other metals.
• Low process temperature. The drying temperature below 200ºC protects the products from metallographic changes.
• A variety of colours. Various colours to suit different purposes.
• Paintable.
