Vinyl Ester Resin Hardener Ratio

You can vary the cure time for polyester vinyl ester resins by reducing or increasing the.

Vinyl ester resin hardener ratio.

It wets out glass very quickly and has low viscosity. 30 drops is approximately equal to one cc. Cc cubic centimeter. 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.

Resin has a short shelf life. Epoxy adheres to wood much better than polyester does. Catalyze 1 5 get a pint for a. Ve resin is a tougher resin because of its longer molecular chains.

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. The styrene in the polyester or vinyl ester resin will melt it. 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.

Mekp is also used with gel coats. It can withstand repeated bending better than both polyester and epoxy resin. The weight of mekp 925 is 1 125 grams per cc. It is meant for a room temperature cure.

Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. It adds excellent strength rigidity adhesion water and chemical resistance. There is a choice of three different hardeners. One gallon of gelcoat weighs approximately 10 5 lbs.

Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin. Vinyl ester resin cures with a tack. It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer. The hardener catalyst for vinyl ester resin and polyester.

Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins. Epoxy resin uses a hardener and polyester vinyl ester resins use a catalyst usually mekp methyl ethyl ketone peroxide. Vinyl ester has a shelf life of 3 months. Our epoxy resins come in either a 2 1 or 4 1 mixing ratio.

When using vinyl ester resin be sure to use it quickly after purchasing. One gallon of polyester resin weighs approximately 9 2 lbs. Oz fluid ounce. Fast medium and slow.

It can be used for corrosion fda applications smc repairs and even resin infusion. It is the same catalyst used with polyester resins. Catalyst chart for polyester resin gel coat and vinyl ester marine resins. Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.

Cloth and polyester resin. Vinylester is essentially a styrene modified epoxy resin. The speed of hardener chosen depends on the temperature in the. Epoxy resin should be used.

Using drops for catalyst measurement is only an estimate.
