Not Recommended For
1. Surfaces must be clean and dry. Remove all oil, grease, soil, drawing and cutting compounds, and other foreign matter by methods outlined in Steel Structures Painting Council Specification SSPC-SP 1, “Solvent Cleaning”.
2. DO NOT USE CHLORINATED SOLVENTS ON STAINLESS STEEL SURFACES.
3. For large surface areas, steam clean with an alkaline detergent, follow by a steam or fresh water wash to remove detrimental residues.
4. For small surface areas, solvent wipe with Dampney 170 Thinner, a chloride free solvent, using proper procedures and precautions to minimize hazards.
|Conventional spray is the recommended method of application. However, Thurmalox 70 may also be applied by airless spray, brush or roller. Do not apply Thurmalox 70 in heavier films than specified since blistering may occur.
|Dry Time 70 F (21 C) 50Percent RH|
|Thurmalox 70 will air dry tack and thumb print free within 1/2 to 1 hour. Allow 8 hours dry time between coats. Allow 24 hours dry time prior to shipping and handling if coating is not heat cured. Stainless steel surfaces coated with Thurmalox 70 in the air dried state can be handled and shipped prior to a heat cure as long as shipping and handling procedures for thin filmed systems are followed. Avoid mechanical abrasion during shipping and handling. Higher temperatures will reduce tack free, recoat and shipping times. Allow one hour solvent flash off period before heat curing or placing into service. Optimum film properties require a heat cure of 350 F (177 C) for 30 minutes. Equipment protected with the Thurmalox 70 in the air-dried state will heat cure when placed into service.|
|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/MSHA 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/MSHA 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.

|Mixing and Application Guidelines|
Redisperse any settled-out pigments by stirring with a paint paddle followed by thorough mixing to a uniform consistency with an explosion-proof or air-driven power mixer. Do not open containers until ready to use. Keep lid on container when not in use.Application Guidelines
Surface temperature must be at least 5 F (3 C) above dew point. For optimum protection apply two coats of Thurmalox 70 to a dry film thickness of 1.5-2.0 mils (37- 50 microns) per coat. Total recommended dry film thickness is 3.0-4.0 mils (75-100 microns).
Thurmalox 70 Air Dry Silicone Coating for Stainless Steel
Prevents Stress Corrosion Cracking Heat Resistant to 1000 F
Thurmalox 70 is an air drying, silicone based heat resistant coating for metal that protects thermally insulated austenitic stainless steel from chloride induced stress corrosion cracking. Thurmalox 70 withstands temperatures to 1000 F (538 C) with peaks to 1100 F (593 C). It is formulated to contain the minimum amounts of attainable chlorides, halides, sulfides, nitrates and metals that induce external stress corrosion cracking. Every batch of Thurmalox 70 is tested by an independent laboratory for leachable chloride content.
This silicone coating for metal is formulated to meet the currently accepted practice for selection of protective coatings for stainless steel surfaces under thermal insulation as set forth in NACE Technical Committee Report 6H189 “A State-of-the-Art Report of Protective Coatings for Carbon Steel and Austenitic Stainless Steel Surfaces Under Thermal Insulation”.
