PROTECTIVE COATING Russian patent published in 2004 - IPC

FIELD: polymer materials.

SUBSTANCE: epoxide oligomer-based polymer composition appropriate for creating waterproofing coatings for composites, steels, and aluminum, contains epoxide resign of the type of 4,4'-isopropylidenediphenol, tetrabromoepoxide resin, organic solvent, and hardener, said organic solvent being acetone/xylene/ethylcellosolve/cyclohexanone mixture. Composition may further contain pigments. Composition allows increasing (by 2-3 times) waterproofness and therefore corrosion resistance and working reliability of parts and assemblies of steel, aluminum alloy, etc. aircraft machinery under elevated humidity conditions.

EFFECT: increased protective efficiency.
