Mixing Ratio For Vinyl Ester Resin

Vinyl ester resins and polyester resins are very close in molecular composition.

Mixing ratio for vinyl ester resin.

30 drops is approximately equal to one cc. Vinyl ester has a shelf life of 3 months. It is typically used between 1 25 to 1 75 1 2 3 ounce to 2 1 3 ounces per gallon. Resins that have duratec in their name require a 2 mix ratio 2 2 3 ounces per gallon.

There is a choice of three different hardeners. One gallon of gelcoat weighs approximately 10 5 lbs. You can mix it 1 to 2 by weight. It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.

By making adjustments to where the catalyst pump is pinned the stroke and thus the catalyst ratio can be adjusted. One gallon of polyester resin weighs approximately 9 2 lbs. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness. Oz fluid ounce.

It is meant for a room temperature cure. Fast medium and slow. Resins that have duratec in their name require a 2 mix ratio 2 2 3 ounces per gallon. Catalyst chart for polyester resin gel coat and vinyl ester marine resins.

The weight of mekp 925 is 1 125 grams per cc. When using vinyl ester resin be sure to use it quickly after purchasing. Our epoxy resins come in either a 2 1 or 4 1 mixing ratio. The difference is that the molecular chain is longer in vinyl ester resin.

Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry. Vinyl ester resin is considered a hybrid of polyester and epoxy meaning its handling characteristics properties and price generally fall just between the other two. Resin has a short shelf life. Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin.

Cc cubic centimeter. It is typically used between 1 25 to 1 75 1 2 3 ounce to 2 1 3 ounces per gallon. The mix ratio is by volume. The styrene in the polyester or vinyl ester resin will melt it.

Mekp is also used with gel coats. The speed of hardener chosen depends. Vinyl ester resin derakane momentum 411 350 epoxy vinyl ester resin is based on bisphenol a epoxy resin and provides resistance to a wide range of acids alkalis bleaches and organic compounds for use in many chemical processing industry. Using drops for catalyst measurement is only an estimate.

For polyester and vinyl ester metered mix machines typically have a large pneumatic resin piston pump and a small catalyst pump slaved to an arm off the main ram.
