SKN Starter is ruggedly constructed, totally enclosed and fixed in sheet metal frame for wall mounting. Conduit holes are provided for cable entry from top and bottom. All incoming and outgoing terminals, conduit entries are easily accessible from top of the starter. An easily removable cover made of sheet metal completely encloses the overload relays and connection terminals to ensure protection against dust and weather. Oil tank, made of deep drawn sheet and fixed with the lower part of the sheet matel completely encloses the overload relays and connection terminals to ensure protection against dust and weather. Oil tank, made of deep drawn sheet and fixed with the lower part of the sheet metal frame, can be easily removed by loosening round nuts from the left and right sides.

Calcium being an auxiliary drier, has little drying action in itself but is very useful in combination with active driers. Zirconium is an active cross-linking agent & as such improves hardness of stoved films as well as their adhesions. Zirconium is not as effective in phenolic resin based media it is recommended as a catalyst for epoxy esters. Use of Lead driers in combination with Zirconium is to be avoided totally. In vehicles that show poor tolerance for lead, calcium can replace part of the lead with a larger amount of calcium to prevent the precipitation of the lead & maintain drying efficiency. Calcium is often used to replace lead where toxicity of lead must be avoided. Calcium is also useful as pigment wetting & dispersing agents & help to improve hardness & gloss & reduce “Silkiness”. When ground with drier adsorbing pigments, calcium minimizes loss of dry by being preferentially absorbed.

In FRP Grade, Cobalt Octoate is combination of two metals. Combined % of two metal is active metal present in Cobalt Octoate. These compounds are promoters used in the curing of polyester and vinyl ester resins with peroxide (MEKP) type catalysts. Promoters are also called accelerators. They can be added to the resin by the supplier, in which case the resin is said to be pre-promoted. Alternatively, promoters can be added by the manufacturer prior to adding catalyst to the resin. 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. Other types of promoters are available, including dim ethyl Analine (DMA). A combination of DMA and cobalt promoters can be used in conjunction with MEKP to give fast cure of polyester resins. 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 ACLR type promoter is added. Promoters must never be mixed directly with catalyst since a violent explosive reaction results. This is why it is important to ensure all promoters are thoroughly mixed with the resin before adding the catalyst
