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.
Vinyl ester resin mixing ratio.
These resins only require about 1 5 catalyst and are quite specific on the ratios especially in hot weather.
One gallon of polyester resin weighs approximately 9 2 lbs.
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.
Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.
When using vinyl ester resin be sure to use it quickly after purchasing.
The weight of mekp 925 is 1 125 grams per cc.
The styrene in the polyester or vinyl ester resin will melt it.
This filler is compatible with epoxy polyester and vinyl ester resin systems.
The molecular chain is longer in vinyl ester resin.
Using drops for catalyst measurement is only an estimate.
The higher percentage by weight.
Vinyl ester resins and polyester resins are very close in molecular composition.
Fast medium and slow.
You will also see vinylester requires a ratio of 2 by volume as opposed to gelcoats and resin which are closer to 1 5.
Vinyl ester has a shelf life of 3 months.
30 drops is approximately equal to one cc.
Mix ratio is 1 2 filler to resin by volume for general use 1 3 filler to resin by volume to reduce runs sagging.
Cc cubic centimeter.
There is a choice of three different hardeners.
Our epoxy resins come in either a 2 1 or 4 1 mixing ratio.
It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.
The speed of hardener chosen depends.
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.
Vinyl ester resins and polyester resins are very close in molecular composition.
Gelcoat and polyester resin including boatyard use a standard catalyst or the 925 catalyst.
Oz fluid ounce.
One gallon of gelcoat weighs approximately 10 5 lbs.
Mixing the correct ratio of a b is extremely important.
Epoxy resin should be used.
Most problems that occur with improper cure is due to not measuring the correct ratio or not mixing completely the two components.
The mix ratio is by volume.
You can mix it 1 to 2 by weight.
