To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. It adds excellent strength rigidity adhesion water and chemical resistance. Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins. It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.

It can be used for corrosion fda applications smc repairs and even resin infusion. Cloth and polyester resin. The speed of hardener chosen depends on the temperature in the. It can withstand repeated bending better than both polyester and epoxy resin.

30 drops is approximately equal to one cc. Resin has a short shelf life. It is the same catalyst used with polyester resins. Vinyl ester has a shelf life of 3 months.

Vinyl ester resin is selected due to its well known performance in marine conditions and good chemical resistance to a wide range of chemicals including sour crude up to 100 c. When using vinyl ester resin be sure to use it quickly after purchasing. Vinylester is essentially a styrene modified epoxy resin. Catalyst chart for polyester resin gel coat and vinyl ester marine resins.

The hardener catalyst for vinyl ester resin and polyester. The styrene in the polyester or vinyl ester resin will melt it. Ve resin is a tougher resin because of its longer molecular chains. Cc cubic centimeter.

Epoxy resin should be used. Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry. It has a measured glass transition temperature t g of 110 c hence allowing the clamp to withstand up to a maximum service temperature of 80 c. It is meant for a room temperature cure.

One gallon of gelcoat weighs approximately 10 5 lbs. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. It wets out glass very quickly and has low viscosity. The hardener catalyst for vinyl ester resin is mekp methyl ethyl ketone peroxide.
