The hardener catalyst for vinyl ester resin and polyester.
Vinyl ester resin hardener ratio.
Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins.
It is the same catalyst used with polyester resins.
The speed of hardener chosen depends on the temperature in the.
Epoxy resin should be used.
Using drops for catalyst measurement is only an estimate.
Catalyze 1 5 get a pint for a.
Oz fluid ounce.
An mekp catalyst is mixed with polyester vinyl ester resin in a very low ratio just a few drops of catalyst per ounce of resin.
Resin has a short shelf life.
The styrene in the polyester or vinyl ester resin will melt it.
It wets out glass very quickly and has low viscosity.
One gallon of polyester resin weighs approximately 9 2 lbs.
To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.
Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.
30 drops is approximately equal to one cc.
The weight of mekp 925 is 1 125 grams per cc.
Catalyst chart for polyester resin gel coat and vinyl ester marine resins.
It can withstand repeated bending better than both polyester and epoxy resin.
Fast medium and slow.
Vinyl ester resin cures with a tack.
It is meant for a room temperature cure.
So if you need vinylester and you have a vertical surface you might consider the reichhold hydrex 100 products.
Epoxy resin uses a hardener and polyester vinyl ester resins use a catalyst usually mekp methyl ethyl ketone peroxide.
You can vary the cure time for polyester vinyl ester resins by reducing or increasing the.
Ve resin is a tougher resin because of its longer molecular chains.
Cloth and polyester resin.
There is a choice of three different hardeners.
One gallon of gelcoat weighs approximately 10 5 lbs.
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.
It has a measured glass transition temperature t g of 110 c hence allowing the clamp to withstand up to a maximum service temperature of 80 c.
Vinylester is essentially a styrene modified epoxy resin.
Try to store the resin in a cool dry place or refrigerate do not freeze it to extend the life of the resin.
It can be used for corrosion fda applications smc repairs and even resin infusion.
Vinyl ester resin is selected due to its well known performance in marine conditions and good chemical resistance to a wide range of chemicals including sour crude up to 100 c.
It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.
Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin.
Hetron 922 l25 vinylesterhetron 922 l25 vinylesterashland s hetron 922 l25 is an incredibly versatile resin.
Mekp is also used with gel coats.
Epoxy adheres to wood much better than polyester does.
It adds excellent strength rigidity adhesion water and chemical resistance.
