XHDAC221 Static-Free Coating
1.Preface
The epoxy resin is the main film-forming agents, chloridize polyethylene rubber is the main modified agents, it is the oil resistance and conducted static bi-component coating.
2.Application
Apply on oil chemical, railway, transportation, oil tank, oil pipeline, storage oil car, and the interior and exterior of oil pipeline and other industry to anti-static protection.
3.Characteristics
1. Good anti-corrosive. Strong adhesion of the coating, aging resistance, water proofing, brushing resistance and other performance
2. Excellent oil resistance: the coating can permanently use in the gas oil, coal oil, diesel oil and lubricant without brushing and polluting the oil.
3. Excellent conduction of electricity: the resistivity is up to the standard GB 6950-201.
Convenient to use and solidify at room temperature, film-forming only one time.

5.Construction
1.Preparation: Mix to no sediments on the barrel bottom before usage, and add side curing agent to coating as 10:1(weight rate), 10:2 in winter below 10¡æ. Use without proper aging after fully mix.
2.Surface treatment: up to national standard Sa2? for metal structure. Or derust by hand, or chemicals to no grease, no rust, no litter, dry and clean. And coating it within 4 hours. Dry to water¡Ü10% before coating concrete.
3.Period: Use out the preperation primer within 1 hour(20¡æ). Do not add the left primer into raw primer.
4.Thickness: Dry thickness is about 70¦Ìm by spraying under high preesure and no gas, and gas spraying, about 60¦Ìm by hand brusing.
5.Comsuption in theory: Generally, comsuption of primer is 0.18kg/m2 without taking into consideration that coating addition, method, technicals, surfaceand its structure, style, and area.
6.Advice application: The better way is spraying under high pressure and no gas for flat film, then gas spraying, the last is hand brushing.
7.Diluent comsuption: According to application to add XHDAC312 diluent unless the coating is too thick, as 3~10%. Do not diluent in water, mellow, lacquar thinner and gasoline. Cover fully to huminity.
8.Clean tools: XHDAC299 cleaning agent for coating tool, or XHDAC221 diluent.
8.Maintenance: It should take 7~10 days to work after coating the last topcoat. Delay if temperature is under 10 ¡æ.
6.Packing and storage
1.Pakage: Sealed is iron barrel, 20kg/barrel. Curing agent and diluent is 15kg/barrel.
2.Storage and Transportation:
It is inflammable. Store cool and ventilation place and far away fire. Do not collide, exposure, rain and near fire in processing of storage and transportation.
3.Period is half year. If exceed, use it against testing. |
