VHT FlameProof Coating was originally developed some 30 years ago and is now used as a protective coating for the white-hot surfaces of space-bound and re-entry vehicles.
Since its inception, numerous industrial, automotive, and electrical engineers have developed new ideas for applications. These include aerospace hardware, smoke stacks, jet engines, heat exchangers, boilers, heaters, exhaust manifolds, mufflers, steam pipes, barbecues, electrical hardware, and countless other applications where resistance to high temperatures and/or weathering is required.
Application: Apply a THIN, even coat - just enough to thoroughly COLOR. Excessive build-up is not necessary or recommended. In applications requiring heavy coating, build-up should be done in stages, each successive coat being cured as recommended below. Nominal coating wet thickness .0015'' - .002''.
VHT FlameProof coatings require no primer. For most economical use of VHT FlameProof colors on ''hard to hide'' surfaces, apply a thin coat of VHT FlameProof White or VHT FlameProof Silver base coating.
Curing: VHT FlameProof coatings will air dry in 15 to 30 minutes and, if handled with reasonable care, may be put to immediate use. Heat curing method for maximum resistance to solvents, salt spray, humidity, thermal shock and heat:
15 minutes at 250°F
30 minutes at 600°F
1 hour at 800°F
30 minutes at 1,000°F
On non-traffic surfaces and where solvent resistance is not required, VHT FlameProof coatings may be used as air-dried. Curing may be accomplished by the inherent heat of operation such as encountered in engine manifolds and exhausts, boilers, heaters, etc. or by following the curing instructions below. ALL CURING SHOULD BE DONE SLOWLY.
