HARD PUTTY (VARIANTS THEREOF) Russian patent published in 2002 - IPC

Abstract RU 2179566 C2

FIELD: finishing paintwork materials for leveling and modelling metal, wood, concrete and ceramic surfaces and for repairing automobile bodies. SUBSTANCE: hard putty comprises, wt parts: unsaturated polyether resin, 100; N, N'- dimethylaniline, 0.08-0.15; benzoyl peroxide, 0.5-1,0; dibutyl phthalate, 1.5-3.0; titanium dioxide, 5.0-10.0; talc, 5.0- 10.0 morshallite, 200-230 or cement, 100-130, thus making it possible to increase shock resistance to 600-800 n/cm, bending elasticity to 20 mm, drying time of hard patty to degree 5 for 10-15 minutes and heat resistance to 175 C. Hard putty preferably comprises 0.1-1.0 % of magnesium oxide. This composition makes it possible to improve tixotropic properties and bending elasticity up to 10 mm. EFFECT: improved properties of the hard putty. 2 cl, 9 ex, 2 tbl
