Recommended as coating on exterior of storage tanks, structural steel and miscellaneous equipment in chemical and refinery facilities. It is designed to have a variable recoat window required due to construction schedules.
- Thinner
- No. 71 (best), Retarder No. 101 or No. 44
- Reduction: with 347.67B Activator
- Below 85°F: Up to 34 oz No. 71 Thinner (3.5 #VOC)
- Up to 50 oz No. 71 Thinner (3.8#VOC)
- Above 85°F: Up to 29 oz No.101 Retarder (3.5#VOC)
- Up to 42 oz No.101 Retarder (3.8# VOC)
- With 347.67C Activator, use No. 71 Thinner only.
- Clean Up Thinner
No. 71 or MEK
- Application Methods
Conventional or airless Spray
- Recommended Substrate
Steel.
- Recommended Primer
Material may be applied directly to properly cleaned metal. For additional corrosion resistance, use No. 349.13 Wilkopon HS Primer Zinc Rich, No. 859.20 Primer WB Inorganic Zinc Rich or 859-06 Primer Inorganic Zinc Rich.
- Recommended Topcoats
Wilkopon Epoxies or Wilkothane HS Polyurethanes. It may be recoated within 2-6 hours (depending on activator used and temperature), or up to 1 year after application. Power wash to remove contaminants if recoated after 1 week. May be recoated wet-on-wetwith epoxies.
- Surface Preparation
- Surface must be clean and dry, free of oil, grease, wax or other contaminants.
- The use of chemical cleaning or pretreatment (e.g., phosphatizing) will help improve the adhesion and will enhance the overall properties of the coating.
- This multi-stage surface preparation is adequate for most industrial applications, and is highly recommended.
- When coating newly fabricated steel, or if heavy mill scale, rust, or loose paint is present on existing structures, clean the parts by mechanical means.
- All sharp edges must be rounded and weld splatter must be removed prior to cleaning.
- Hand, power tool or SP7 Brush Blast Cleaning will afford minimum protection.
- For maximum protection of steel surface, dry abrasive blast to a Commercial Blast Finish in accordance with SSPC-SP6.
- Apply prior to the development of surface rust, usually within 8 hours or less especially in humid conditions.
