Vinyl Ester Resin Mixing Ratio

Most problems that occur with improper cure is due to not measuring the correct ratio or not mixing completely the two components.

Vinyl ester resin mixing ratio.

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. The speed of hardener chosen depends. The mix ratio is by volume. Oz fluid ounce.

When using vinyl ester resin be sure to use it quickly after purchasing. Vinyl ester resins and polyester resins are very close in molecular composition. 30 drops is approximately equal to one cc. One gallon of polyester resin weighs approximately 9 2 lbs.

Gelcoat and polyester resin including boatyard use a standard catalyst or the 925 catalyst. Fast medium and slow. One gallon of gelcoat weighs approximately 10 5 lbs. You can mix it 1 to 2 by weight.

Using drops for catalyst measurement is only an estimate. These resins only require about 1 5 catalyst and are quite specific on the ratios especially in hot weather. The weight of mekp 925 is 1 125 grams per cc. Resin has a short shelf life.

Vinyl ester has a shelf life of 3 months. Mix ratio is 1 2 filler to resin by volume for general use 1 3 filler to resin by volume to reduce runs sagging. Epoxy resin should be used. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.

Mixing the correct ratio of a b is extremely important. The difference is that the molecular chain is longer in vinyl ester resin. Catalyst chart for polyester resin gel coat and vinyl ester marine resins. This filler is compatible with epoxy polyester and vinyl ester resin systems.

The higher percentage by weight. The molecular chain is longer in vinyl ester resin. The styrene in the polyester or vinyl ester resin will melt it. Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.

Our epoxy resins come in either a 2 1 or 4 1 mixing ratio. Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin. You will also see vinylester requires a ratio of 2 by volume as opposed to gelcoats and resin which are closer to 1 5. There is a choice of three different hardeners.

Add filler after adding catalyst to resin.
