More Information
Summary:Compsn. comprises (a) prepolymer with >=2 ethylenic unsatd. gps., formed by reacting a urethane prepolymer with an ethylenic unsatd. monomer and (b) a filler contng. >=50 wt. % of particles not >100 mu. A catalyst is also used which is either a mixt. of peroxide and accelerator or a photosensitive catalyst. The filler is pref. borosilicate glass and the monomer is e.g. CH2=C(R3)-COOH where R is H or hydrocarbyl.
