Promoters - Accelerators
Accelerators are compounds used in the polyester and vinyl ester resins to speed up the curing reaction. Most of the Poliyas resins and gelcoats are pre-promoted. Depending on conditions, promoters can be added by the composite manufacturer prior to adding catalyst to the resin. In general cobalt-based promoter helps the catalyst to start the chemical reaction between the resin and styrene monomer and form a cured solid.
Cobalt Promoters
Cobalt 1% solution 25 kg/Canister
Cobalt 6% solution 24 kg/Canister
Cobalt 8% solution 5 kg/Canister
Cobalt 8% solution 25 kg/Canister
The industry standard Cobalt 6% is an abbreviation for the compounds cobalt napthenate and cobalt octoate, usually supplied as a 6% solution. These compounds are promoters used in the curing of polyester and vinyl ester resins with methyl ethyl ketone peroxide (MEKP) type catalysts.
The purpose of cobalt-based promoters is to speed up the curing reaction of polyester and vinyl ester resins and allow them to cure at room temperature. The cobalt-based promoter helps the catalyst to start the chemical reaction between the resin and styrene monomer and form a cured solid. The exact amount of promoter added to the resin will depend on the resin used, the temperature in the workshop and the gel time desired. Usually 0.1 to 1% (based on the mass of resin) of cobalt 6% type promoter is added.
Pergaquick A 200
DMA - Dimethylaniline
25 kg/Canister
It is a promoter used in the curing of polyester and vinyl ester resins. DMA can be used on its own with benzoyl peroxide (BPO) type catalysts or in combination with cobalt 6% promoters with methyl ethyl ketone (MEKP) type catalysts. These systems give rapid cure at room temperature.
DMA is used to speed up the radical formation in a controllable way and allow polyester and vinyl ester resins to cure at room temperature.The exact amount of promoter added to the resin will depend on the resin used, the temperature in the workshop and the gel time desired. Usually 0.05-0.6% (based on the mass of resin) of DMA promoter is added.
