Catalysts and Accelerators



Catalysts are chemical additives used in various processes in order to accelerate the reaction, so they can also be called Accelerators. These additives can speed up polymerization or curing reactions, for example, considerably shortening the reaction time.

There are catalysts that come into action when the temperature rises, but there are also some that work at room temperature, being useful in processes where the temperature must be maintained.

The catalytic effect is due to the fact that the additive decreases the activation energy of a reaction, so that less energy needs to be expended for it to occur.

Brasnox® DM 50

Main application: it is a polymerization initiator in unsaturated polyester resins and vinyl ester, at room temperature. Applications in hand lay-up, spray-up, continuous tile lamination, filament widing and closed molding processes can be used for the application of gelcoats and plastic doughs.

Butanox- M50

Clear liquid, composed of methyl ethyl ketone peroxide, of medium reactivity, desensitized with dimethylphthalate. Indicated as a cure catalyst for unsaturated, orthophthalic, isophthalic polyester resins of medium or high reactivity to room temperature in the presence of accelerators.

Cobalt 6%

It is an accelerator for non-accelerated general polyester resins. Used in conjunction with mek V-50 catalyst (methyl ethyl ketone peroxide). The percentage of cobalt accelerator varies from 0.3% to 0.6% in relation to the amount of resin being used.

Dimethyl Aniline Accelerator (DMA)

It is an accelerator for non-accelerated general polyester resin. Used in conjunction with DIBENZOILLE PEROXIDE. The percentage of dimethyl aniline accelerator varies from 0.3% to 0.6% in relation to the amount of resin being used.
