Product
strengths:
Excellent exterior durability. Excellent
resistance to animal, vegetable fats and oils,
petroleum oils and aliphatic hydrocarbons. Good
stain resistance. Good colour retention. The
inert fluorine modified coating is based on Kynar
500 resin developed by the Pennwalt Corporation
Product
Limitations:
Poor mar resistance.
Life
to first maintenance: In most temperate
environments a life to first maintenance of the
coating of over 20 years can be expected.

typical properties and do not constitute a
specification
First
maintenance:
is defined as the stage when for appearance
reasons the cladding may require over-painting,
although the coating will be protecting the steel
substrate
