|Only thin Thurmalox 218/219 coatings with Dampney 162 Thinner. Do not thin beyond federal, state and/or local VOC emission regulations.
Note: Use of other thinners not approved by Dampney may hinder product performance and void product warranty.
|Thoroughly flush spray equipment and hoses immediately after use with Dampney 162 Thinner. Dismantle spray equipment and clean parts, brushes and rollers with Dampney 162 Thinner.|
|Storage||Store in a cool, dry place with temperature between 50 F and 100 F (10 C and 38 C). Keep container closed when not in use.|
|1 Note 218 will change to amber color at 250 F (121 C). This is normal.
2 Note 218 will change to amber color at 250 F (121 C). This is normal.
3 A temperature of 160 F (71 C) must be achieved for the coating system to withstand hot/boiling water.
4 A temperature of 160 F (71 C) must be achieved for the coating system to withstand hot/boiling water.

1. To ensure optimum long-term coating system performance, surfaces must be clean, dry and free from dirt, oil, grease, salts, welding flux, mill scale, rust, oxides, old paint, corrosion products or other foreign matter.
2. Remove all surface imperfections that will induce premature coating system failure. Chip or scrape off weld splatter. Grind down sharp and rough edges, gouges, and pits.
3. Abrasive blast surface per specification SSPC-SP 10, “Near-White Blast Cleaning”, or per NACE Standard No. 2 to a profile depth of 1.5 – 2.0 mils. Abrasive used in blasting should be selected carefully from materials of mesh size required to produce the desired anchor pattern.
Applications Guidelines –
Insulated Carbon and Stainless Steel – Maximum average DFT is 15-18 mils (375-450 microns).
Applications Guidelines –
Uninsulated Stainless and Carbon Steel – Total average DFT system is 15-18 mils (375-450 microns).
Thurmalox 218 Primer and Thurmalox 219 Topcoat are two component coatings consisting of a Part A and Part B that must be mixed together before use. The mix ratio for Thurmalox 218 is 4:1 and that of Thurmalox 219 is 2:1 by volume. The individual component should be mixed separately to disperse pigment uniformly. Add Part B to Part A and mix thoroughly with a low-speed power mixer for a minimum of 3 minutes or until mixed coating is completely blended and of uniform color.
|Thurmalox 218/219 coatings may be applied by Conventional and airless spray
Procedures for Application to Hot Surfaces
For conventional spray use adequate air pressure and volume to obtain proper atomization. Be aware that procedures for applying coatings to hot surfaces are somewhat different from those normally used for application to ambient temperature surfaces.
|Cure Time 160 F (71 C) 50% RH|
|Thurmalox 218/219 Coating System will cure within 8 hours. Allow 4 hours dry time between coats. A temperature of 160 F (71 C) must be achieved for the coating system to withstand hot/boiling water. Higher application temperature will reduce cure time.|
|WARNING: Flammable Liquid and Vapor Keep away from heat, sparks and flame. Vapors may cause flash fire. Do not breathe vapors or spray mist. Avoid contact with eyes, skin and clothing. Use with adequate ventilation during mixing and application. Wear an appropriate, properly fitted organic vapor cartridge-type respirator (NIOSH approved) during and after application unless air monitoring demonstrates vapor/mist levels are below applicable limits. Follow respirator manufacturers directions for respirator use. Wash thoroughly after handling. Wear protective gloves, chemical safety goggles and impervious protective clothing. Use skin cream. In confined spaces it is required to use a positive pressure supplied-air respirator (NIOSH approved). Use explosion-proof lights and electrical equipment. Use only nonsparking tools and equipment. Wear conductive and nonsparking footwear. Make certain all electrical equipment is grounded. Observe all safety precautions and follow procedures described in OSHA regulations. See Material Safety Data Sheet (MSDS) for complete precautionary and disposal information.
If instructions and warnings cannot be strictly followed, do not use this product.

Thurmalox 218 Primer/219 Topcoat Coating Under Insulation (CUI) System
Wet/Dry Thermal Cycling to 450 F Apply Directly to Hot Steel
Thurmalox 218 Primer/219 Topcoat System are VOC compliant, high build, modified silicone coating formulated for the protection of metal surfaces under insulation exposed to temperatures from ambient to 450 F (232 C). This coating system is specifically formulated to be applied directly to hot steel having a metal temperature of up to 450 F (232 C) during application. Thurmalox 218/219 performs exceptionally in continuous immersion of hot and/or boiling water. It has excellent resistance to continuous and/or rapid wet-dry-wet thermal cycling to 450 F (232 C). Thurmalox 218/219 are durable, tough coatings able to withstand severe thermal shock as well as excellent chemical resistance.
