Thurmalox 8886 Series
Heat Resistant Coating
Generic Type: Two Component Silicone Copolymer
Description
A high performance two component high temperature silicone copolymer for service in harsh environments, it forms a tough durable film that adheres strongly to properly prepared surfaces. Thurmalox 8886 provides long term durability in weathering conditions as well as temperature resistance and acts as a barrier coating against chemical attack from glycol cooling agents and synthetic lubricants at operating temperatures up to 450°F (232°C).
Recommended Uses
· Valves Castings
· Pump, pump housing and sump
· Air compressors, exhaust systems, pipes etc.
Not Recommended For
· Immersion in aromatic hydrocarbons
Features
· Resistance to elevated temperatures
· Long-term durability and weather resistance
Limitations
Do not apply at temperatures below 60°F (16°C) or under conditions where temperatures may drop below 60°F (16°C) within 24 hrs after application. Do not apply Thurmalox 8886 series when the surface temperature is less than 5°F above the dew point. Do not apply to previously coated surfaces without checking for coating compatibility and adhesion to previously primed or coated surfaces.
Substrates
Clean, smooth carbon-steel stainless steel, blasted steel, phosphatized steel, galvanized, copper, aluminum, and primed steel.
Surface Preparation
Surface must be clean and dry. Remove all oil, grease, soil, drawing and cutting compounds, and other foreign matter detrimental to the adhesion of this coating as outlined in SSPC-SP 1 “Solvent Cleaning”.
All machined steel, copper and aluminum surfaces are to be prepared according to SSPC-TR/NACE 6G194 (phosphate cleaning) and all carbon steel and cast iron surfaces are to be prepared following “SSPC-SP10 Near-white Blast Cleaning Standard” leaving a 2 – 2.5 mil profile in all blasted surfaces.
Mixing
Thurmalox 8886 is a two component coating consisting of part A and part B which must be mixed together before use. The mix ratio for Thurmalox 8886 is two (2) to one (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 power mixer until mixed completely and of a uniform color. Do not open container until ready to use. Keep lid on container when not in use.
Pot Life
Thurmalox 8886 is a two (2) component product which has a pot life of 12 hours at 70°F (21°C). Keep container closed when not in use. If a skin forms on surface, do not mix in, remove from container.
Thinning
This product is ready to use as shipped, thinning is not normally required. If thinning is required us Dampney 100 thinner. Over thinning may hinder product performance and void product warranty.
Application Equipment
Brush application: Touch-up only.
Spray equipment: A wide variety of spray equipment can be used, such as airless, standard conventional, conventional HVLP, Conventional HTE or air assisted airless.
Dry Time 70°F (21°C) 50% RH
Thurmalox 8886 will dry to touch in 4 hours at 70°F (21°C) and 50% RH. Cure time will vary with type of heat used and substrate mass.
Cleanup
Thoroughly flush spray equipment and hoses immediately after use with Dampney 100 Thinner.

Precautionary Information
WARNING: Flammable liquid and Vapor
Inhalation of vapor or spray mist can cause headache or nausea and irritation of the nose, throat and lungs. Hazards Keep away from heat, and flame. Do not breathe vapors or spray mist. Avoid contact with eyes, skin and clothing. Use only with adequate ventilation during mixing and application. Respiratory protection is not required if good ventilation is maintained. 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). Observe all safety precautions and follow procedures described in OSHA regulations.
See Material Safety Data Sheet (MSDS) for complete precautionary information.
If instructions and warnings cannot be strictly followed, do not use this product.
