Vinyl Ester Resin Hardener Ratio

The speed of hardener chosen depends on the temperature in the.

Vinyl ester resin hardener ratio.

The weight of mekp 925 is 1 125 grams per cc. It is meant for a room temperature cure. To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. Cc cubic centimeter.

Our epoxy resins come in either a 2 1 or 4 1 mixing ratio. Vinylester is essentially a styrene modified epoxy resin. Epoxy resin should be used. Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.

It can withstand repeated bending better than both polyester and epoxy resin. 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. It wets out glass very quickly and has low viscosity. The hardener catalyst for vinyl ester resin is mekp methyl ethyl ketone peroxide.

Hetron 922 l25 vinylesterhetron 922 l25 vinylesterashland s hetron 922 l25 is an incredibly versatile resin. Vinyl ester has a shelf life of 3 months. So if you need vinylester and you have a vertical surface you might consider the reichhold hydrex 100 products. Ve resin is a tougher resin because of its longer molecular chains.

Epoxy resin uses a hardener and polyester vinyl ester resins use a catalyst usually mekp methyl ethyl ketone peroxide. There is a choice of three different hardeners. Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins. The hardener catalyst for vinyl ester resin and polyester.

One gallon of polyester resin weighs approximately 9 2 lbs. Epoxy adheres to wood much better than polyester does. It can be used for corrosion fda applications smc repairs and even resin infusion. Catalyst chart for polyester resin gel coat and vinyl ester marine resins.

Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin. 30 drops is approximately equal to one cc. It adds excellent strength rigidity adhesion water and chemical resistance. It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.

You can vary the cure time for polyester vinyl ester resins by reducing or increasing the. An mekp catalyst is mixed with polyester vinyl ester resin in a very low ratio just a few drops of catalyst per ounce of resin. Catalyze 1 5 get a pint for a. When using vinyl ester resin be sure to use it quickly after purchasing.

Cloth and polyester resin. Vinyl ester resin cures with a tack. Resin has a short shelf life. One gallon of gelcoat weighs approximately 10 5 lbs.

Using drops for catalyst measurement is only an estimate. It is the same catalyst used with polyester resins. 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. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin.

Mekp is also used with gel coats.
