Application:

1.EMULSION POLYMERISATION:

Initiator for the emulsion polymerisation of vinyl acetate, (meth-) acrylates and

acrylic resin paint dispersions in combination with suitable reducing agents

(Fe-salts, sulphites, dithionites, RONGALITE, ascorbic acid or sugar).

Temperature range: 50 - 80 °C

Dosage level: 0.1 - 0.5 % as supplied

Particularly suitable for reduction of residual monomer.

2.COPOLYMERISATION:

Initiator for the copolymerisation of styrene / butadiene or acrylnitrile /

butadiene / styrene in emulsion.

In combination with redox systems polymerisation temperatures are possible

between 5 and 25 °C.

Dosage level: 0.1 - 0.3 % as supplied

3.used for the curing of unsaturated polyester resins and polymerization of styrene alkyde mixtures
