PHOTOHARDENING COMPOSITION FOR COVER Russian patent published in 2008 - IPC C09D5/08 C09D167/06 C09D181/04 

FIELD: polymeric materials.

SUBSTANCE: invention relates to polymeric protective materials and can be used for creature of anticorrosive covers. Photohardening composition for cover comprises the following components, mas. p. p.: polysulfide oligomer, 5-10, unsaturated polyester resin, 100-105, and a photoinitiating agent, 3-6. Resin of sort PN-9119 is used as unsaturated polyester resin that represents products of polycondensation of propylene glycol with dimethylterephthalate and maleic anhydride dissolved in styrene (the styrene concentration is 35-45%). Proposed composition provides the high hardening rate to obtain materials showing the high cross-linking frequency and regularity of structure that enhance bending and stretching strength, resistance against corrosion and adhesion properties of the cover.

EFFECT: improved and valuable properties of composition.
