When using vinyl ester resin be sure to use it quickly after purchasing.
Mixing ratio for vinyl ester resin.
Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin.
The styrene in the polyester or vinyl ester resin will melt it.
Catalyst chart for polyester resin gel coat and vinyl ester marine resins.
It is typically used between 1 25 to 1 75 1 2 3 ounce to 2 1 3 ounces per gallon.
Vinyl ester resins and polyester resins are very close in molecular composition.
There is a choice of three different hardeners.
The weight of mekp 925 is 1 125 grams per cc.
Using drops for catalyst measurement is only an estimate.
You can mix it 1 to 2 by weight.
One gallon of polyester resin weighs approximately 9 2 lbs.
Our epoxy resins come in either a 2 1 or 4 1 mixing ratio.
Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.
It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness.
It is meant for a room temperature cure.
Resins that have duratec in their name require a 2 mix ratio 2 2 3 ounces per gallon.
One gallon of gelcoat weighs approximately 10 5 lbs.
Cc cubic centimeter.
Fast medium and slow.
Resin has a short shelf life.
Epoxy resin should be used.
The higher percentage by weight.
Vinyl ester has a shelf life of 3 months.
Oz fluid ounce.
It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.
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.
By making adjustments to where the catalyst pump is pinned the stroke and thus the catalyst ratio can be adjusted.
The mix ratio is by volume.
Resins that have duratec in their name require a 2 mix ratio 2 2 3 ounces per gallon.
30 drops is approximately equal to one cc.
The speed of hardener chosen depends.
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.
Mekp is also used with gel coats.
Mekp is a liquid polymerization initiator for the room temperature cure of specialized unsaturated polyester and vinyl ester resins.
