Stainless Steel and Other Non-Ferrous Metals
Surfaces must be clean and dry. Remove all oil, grease, oil and other foreign matter by methods outlined in Steel Structures Painting Council Specification SSPC-SP1, “Solvent Cleaning”. Surface to be coated shall be prepared in accordance with SSPC-SP16 or equivalent with MBX Bristle Blaster. A sharp angular blast profile of 0.75-1.0 mils (20-25 μm) is required.
Apply two coats Thurmalox 884-050 to a dry film thickness of 1.0-2.0 mils (25-50 μm) per coat allowing for proper curing between coats.
Existing Coated Surfaces
Thurmalox 884-080 may be applied over existing coated surfaces which have been abraded and/or power washed to remove surface contamination. Dampney assumes no liability for existing coated surfaces and suggests a test patch be applied to ensure compatibility and proper adhesion. Apply two coats Thurmalox 884-050 to a dry film thickness of 1.0- 2.0 mils (25-50 μm) per coat allowing for proper curing between coats.
Mixing
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 Equipment
Do not apply Thurmalox 884-050 coating in heavier films than specified as blistering or cracking may occur.
Conventional Spray (preferred spray method):
- Spray gun : DeVilbiss JGA402 or equal
- Fluid tip : EF
- Air cap : 704
- Fluid hose : 3/8” ID
- Air hose : 5/16” ID
- Atomizing pressure : 60 psi
Provide material pot with agitator, regulators for fluid and air pressure, and oil and moisture traps in supply line. Smaller diameter Hose may require increased pressure.
Airless Spray
- Pump Size : 30:1 or higher
- Gun : Silver Gun
- Tip Size : 313-315 or 613-615
Brush : Use an industrial grade brush with short China bristles. Do not use synthetic-bristled brushes. Do not flood surface with coating. Brush out thoroughly, maintaining a continuous wet edge and uniform appearing paint film.
Roller : Use solvent resistant short nap 1/4” (6 mm) mohair roller cover with phenolic core. Do not flood surface with coating. Roll out excess coating on a suitable, screened surface. Then roll out thoroughly, maintaining a continuous wet edge and uniform appearing paint film.
Thinning (not typically required)
While thinning is not normally required for viscosity a maximum of 3% by volume Dampney 112 thinner can be used if encountering dry spray. Do not thin beyond federal, state and/or local VOC (volatile organic compound) emission regulations. Note: Use of other thinner not approved by Dampney may hinder product performance and void product warranty.
Cleanup
Thoroughly flush spray equipment and hoses immediately after use with Dampney 100 Thinner. Dismantle spray equipment and clean parts, brushes and rollers with Dampney 100 or 112 Thinner.

- Color Change Summary
Ambient to 250°F (121°C) Bright Red 300˚ (149°C) to 450°F (232°C) (changes through entire range) Bright Red to Pink
Note : Color change is dependent on variables such as time, temperature and thickness of steel surface. Color change or drift is possible based on these variables. Thurmalox 884-050 may require repainting every 18-24 months depending on operating conditions.

Technical Details & Test Data
- Dry Time at 70°F (21°C) 50% RH
Thurmalox 884-050 coating will air dry tack and thumb print free within 2 hours. Allow 8 hours dry time between coats. Allow 24 hours dry time prior to shipping and handling if coating is not heat cured. Surfaces coated with Thurmalox 884-050 in the airdried state can be handled and shipped prior to a heat cure. However, care should be taken to avoidmechanical abrasion during shipping and handling. Allow one hour solvent flash off period before heat curing or placing into service. Equipment protected with the Thurmalox 884-050 coating in the air dried state will reach full physical properties when placed into service.
Safety & Health
- Precautionary Information
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 manufacturer’s 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.
