Abstract
The present invention relates to an epoxy-based thermally insulating paint composition and its specific use for coating the surface, in particular the inner surface, of oil and gas pipes. The oil and gas pipes thus coated have excellent insulating properties and the formation of undesired waxes or hydrates is significantly reduced. The composition typically comprises 30-70% by solids volume of an epoxy based binder system, 10-50% by solids volume of hollow microspheres, and 1-25% by solid volume of further paint constituents.
