A paint composition comprising:
- a resin constituent consisting essentially of
- i) a non-aromatic epoxy resin having the formula:
- ii) a polysiloxane having the formula:
- where R1 is a hydroxyl or an alkyl, aryl or alkoxy group having up to 6 carbon atoms, R2 is a hydrogen or an alkyl or aryl group having up to 6 carbon atoms and n is a number selected so that the molar mass of the polysiloxane is within the range of 400 to 2000, and
- iii) an epoxy silane which acts as a crosslinking agent between the epoxy and siloxane chains.
