Super Anti-Corrosion: Ruspert Coating

Perhaps you have heard of many screw surface treatments such as galvanizing, phosphating, and even dacromet. The main function of these surface treatment processes is anti-corrosion, and ruspert is an emerging, higher-level anti-corrosion treatment process.

Ruspert coating, also known as ceramic coating, is a coating introduced for construction screws. It consists of three layers:

• First layer: Metalliczinc layer
• Second layer: Special chemical conversion film
• The third layer: Anti-rust layer (Baked ceramic surfacecoating)

The advantages are as follows:

1.Excellent corrosion resistance: 500-1500Hours salt spray test

• Timber Preservative Resistance: Ruspert’s high resistance to high humidity and high salt conditions makes it suitable for use on treated wood.
• Contact Corrosion Resistance: Ruspert will not have contact corrosion problems with other metals or metal-coated materials in wet and dry condition

2.Low baking temperature: Within 200 degrees Celsius, to avoid the occurrence of parts tempering, hardness reduction, fracture and other problems

3.Colorful: can modulate colors according to customer requirements

4.The surface finish and adhesion performance: Stronger than dacromet, more beautiful, and can better meet the needs of customers.

Ruspert coating (also called ceramic coating) is a high-grade protective coating to prevent metals from corrosion in various pollutive and atmospheric conditions. The surface is usually in silver color but can come in range of colors depending on the application. Ruspert coating consists of three layers:

• The 1st layer: Metallic zinc layer

• The 2nd layer: Special chemical conversion coating layer

• The 3rd layer: Rustproof layer (Baked ceramic surface coating layer)

All DD Fastener screws with Ruspert coating can provide anti-corrosion performance of 500 hours, 1000 hours and 1500 hours neutral salt spray test.

The unique feature of Ruspert Coating is the tight joining of the baked ceramic top coating and the chemical conversion film thanks to the cross-linking effect. These three layers are bonded together with the metallic zinc layer through chemical reactions, and this unique method of combining layers results in a rigid and dense combination of the coating films.
