JL Dacromet Special Primer

JL Dacromet Special Primer First, What Is Dacromet? Dacromet is a representative high technology on metal surface treatment in the world. It is invented by American first, then was buyout by Japanese, now it has been introduced in by China, and become a proprietary control technology of China. Set of closed process equipment with the whole process of re-coating cycle way, revolutionized the plating process, plating process to eliminate the pollutions, such as acid, alkaline, zinc, chromium and other wastewater, air emissions, and so on. After the process of “Skimmed -Shot -Curing - Cooling – Product” a silver salt corrosion coating which composed zinc flake formation, aluminum and chrome turned out. All the materials made by the process are all through the gasification of water, no pollution and public nuisance. In industrialized countries, it has been widely applied, gradually to replace the heavily polluting galvanized, electroplating, galvanizing, hot zinc spray, mechanical galvanized, zinc-based alloy coating, oxidation, phosphate and other traditional surface treatment technology, in order to reduce the environmental contamination radically. Second, The Corrosion Mechanism Of Dacromet The Corrosion Mechanism of Dacromet: Dacromet is a new metal rust system. The main mechanism of anti-rust coating: electrochemical protection by zinc matrix controlled, the role of chromate passivation, shielding effect by zinc chromate coated aluminum, and "elutriation" effect made by zinc and aluminum. Third, The Technology Characteristics of Dacromet: Dacromet is an advanced, full high-tech on metal surface treatment, it has advantages other technology unmatched. 1. Superior corrosion resistance. The film didn’t protected by dacromet usually etching 1μm 3μm thick after 10 hours of salt spray corrosion test. However, the dacromet film only etching 1μm, which is 10 times of the normal ones. Dacromet can last 1000hours in the salt spray corrosion test. It also has anti-sulfur dioxide high-tech, so it has superior corrosion resistance. 2. Excellent heat resistance. Traditional galvanized layer may has small cracks when the temperature is above 70 °C, its color also will be changed in the condition of 200 300 °C, and usually its corrosion resistance also declined significantly. Dacromet corrosion film is made by 300°C when in the process of curing, so the surface can remain unchanged even in high temperature for a long time, and its corrosion has no change. 3. Excellent high permeability. The metal parts after be treated by dacromet has an anti-corrosion coat which has the character of deep penetration. The deep coating capacity of dacromet is far better than galvanized. 4. No hydrogen embrittlement. Hydrogen embrittlement is a problem that can not overcome by the traditional galvanizing process. However, in the process of Dacromet, there has no any acid treatment, so there is no problem of hydrogen permeation time of plating. Coupled with the high temperature curing, so Dacromet absolutely no hydrogen embrittlement phenomenon. 5. Good weather resistance. 6. A beautiful matte silver-gray appearance of the coating. The workpiece after the treatment of dacromet technology, the metal surface is matte silver, which is very beautiful and generous. And the re-coated surface of Dacromet has good adhesion to paint, so it can be re-painted in a variety of colors. Main components: Special acrylic resin, imported paint, thinner, functional additives Usage: Specially used for Dacromet seal. Dry time: Touch dry: 2-3 minutes Recoat time: 10 minutes Package: 20kg/barrel Storage: Sealed to storage in a cool dry place (0-40 degrees Celsius ),and must be prevented from frost. Advantages: JL Dacromet Special Primer has excellent corrosion resistance, strong erosion of the chemical materials. There are high-gloss, semi-light and matt colorful films be available. Excellent acid resistance can effectively prevent from the fading. It also anti-contamination, easy cleaning. Surface Treatment Spray dacromet coating first to make sure the surface without sewage, oil, dust or other debris. Spray recommendation: 1.Read the instructions first; 2. Theoretical Coverage: Theoretically it may cover 8-10 square meters per kilogram. 3. Tools: brush, roller, ordinary spray or airless spray 4. Cleaning: wash tools with clean water. 5. Application environment: It is not suitable application for relative humidity is higher than 85% or temperature bellow 5C. 6. Don’t mix the used with the unused.
