  • Applications

    For some special applications it is desirable to use a dry benzoyl peroxide powder as a catalyst. For these cases the benzoyl peroxide formulation Perkadox® 33 was introduced, which is a mixture of benzoyl peroxide and filler. Perkadox® 33 can be handled very easily and without risk. It contains no plasticizer and is lower concentrated than the usual benzoyl peroxide formulations, which makes dosing easier. One of the most important applications for Perkadox® 33 is as a catalyst for putties based on unsaturated polyester resins. A putty containing an accelerated polyester resin and Perkadox® 33 cures rapidly so that after a short time the surface can be sanded and polished. The putty is made of two components, viz.: a) A powder consisting of a mixture of filler with pigment and Perkadox® 33 as a catalyst. b) A liquid component consisting of polyester resin and N,N-Dimethylaniline (10% formulation in aliphatic ester) or N,N-dimethylparatoluidine (10% formulation in aliphatic ester), or alternatively, a polyester resin with a built-in amine accelerator. When the putty has to be applied component a) and b) are mixed. The manufacturer of these putties should take care that the powder contains Perkadox® 33 and the liquid component the Accelerator, in such amounts that after mixing the two components there is enough time to apply the putty.
