Excellent Anti-Corrosion Coating for Steel Structure

VCI-396 Super Anti-corrosion Premier Coating                              1. VCI-396 Quick Details State: Liquid coating                     Color: Aluminum Net weight:20kg                        Application Method: spray Main Raw Material: Polyurethane         Coverage: 21m2/kg@25μm 23m2/L@25μm 2. VCI-396 Description: VCI-396 is high solid content, moisture-curing polyurethane anti-corrosion coating with leading vapor corrosion inhibitors(VCI) technology. VCI works by emitting a vapor which forms a microscopic layer on metal surfaces. This layer offers additional protection and act as a barrier inhibiting the contact with chemical compounds or corrosive materials. Therefore, VCI-396 is able to protect metal components against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals. Usually, VCI-396 premier is qualified for many occasions, also we offer special finish coating to match our VCI-396 premier to meet higher requirements. VCI-396 is inclined to provide triple layers to stop the corrosion. Layer 1: high performance pure polyurethane film Layer 2: superfine aluminum powder Layer 3: VCI vapor corrosion inhibitors 3. VCI-396 Advantages: Superior protection against corrosion, workable on ferrous and aluminum metals Excellent mechanical property(impact resistance, hardness, adhesion etc.) Advanced VCI technology, triple layers against corrosion Easy application and can be applicable in moist or low temperature environment Single component, low VOC and high solid content Excellent resistance to weathering, chemicals Can be used as primer and topcoat Easy to maintain and cost effective 4. Where to use: 1. Bridges, Machinery and equipment, metal roofs 2. Steelwork, metal tank and container, metal pipe 3. Decks, ducts, carbon steel, stainless steel, alloy 4. Chemical pants, oil refineries, public utility works 5.

Shelf Life: 12 months in its original container Delivery Time: About 14days after order confirmed 6. Installation Application VCI-396 is formulated to be as supplied. Ensure uniform consistency prior to use 1. Recommended application temperature is -7 º C-38 º C, ventilation is needed, fireproof tools are needed; 2. Maximum performance of VCI-396 can be achieved only when the metal surfaces to be   protected are clean, dry and free of rust, oil and mill scale. 3. Decide the thickness based on actual requirements and the first layer should be about 25μm, subsequent layer thickness no more than 50μm. Application is forbidden before previous layer be dry, and total thickness is achieved layer by layer . 4. Recommended thickness is 25μm, 21/kg, loss should be in consideration in application. VCI-396 Application Notes: 1. Mixing, mixing time is more than 2 minutes until homogeneous(nothing added), then placed for 10 minutes before application. 2. Application is proceeded when the temperature above 5 º C, humidity between 20%-90% 3. Remaining coating should be sealed from air, storage 0 º C-40 º C. 4. Application tools should be washed immediately after application. 5.PLEASE FEEL FREE TO CONTACT IF YOU HAVE ANY QUESTION.
