The weight of mekp 925 is 1 125 grams per cc.
Vinyl ester resin mixing ratio.
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.
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.
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.
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.
There is a choice of three different hardeners.
Resin has a short shelf life.
The molecular chain is longer in vinyl ester resin.
Mixing the correct ratio of a b is extremely important.
You will also see vinylester requires a ratio of 2 by volume as opposed to gelcoats and resin which are closer to 1 5.
Our epoxy resins come in either a 2 1 or 4 1 mixing ratio.
Epoxy resin should be used.
The mix ratio is by volume.
Vinyl ester resins and polyester resins are very close in molecular composition.
The difference is that the molecular chain is longer in vinyl ester resin.
You can mix it 1 to 2 by weight.
Cc cubic centimeter.
Fast medium and slow.
Vinyl ester has a shelf life of 3 months.
These resins only require about 1 5 catalyst and are quite specific on the ratios especially in hot weather.
This filler is compatible with epoxy polyester and vinyl ester resin systems.
Add filler after adding catalyst to resin.
The higher percentage by weight.
Most problems that occur with improper cure is due to not measuring the correct ratio or not mixing completely the two components.
Mix ratio is 1 2 filler to resin by volume for general use 1 3 filler to resin by volume to reduce runs sagging.
When using vinyl ester resin be sure to use it quickly after purchasing.
The styrene in the polyester or vinyl ester resin will melt it.
Using drops for catalyst measurement is only an estimate.
Vinyl ester resins and polyester resins are very close in molecular composition.
The speed of hardener chosen depends.
