Hetron 922 l25 vinylesterhetron 922 l25 vinylesterashland s hetron 922 l25 is an incredibly versatile resin.
Vinyl ester resin hardener ratio.
Vinylester is essentially a styrene modified epoxy resin.
One gallon of polyester resin weighs approximately 9 2 lbs.
Cc cubic centimeter.
One gallon of gelcoat weighs approximately 10 5 lbs.
It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer.
It can withstand repeated bending better than both polyester and 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.
Epoxy resin should be used.
Epoxy resin uses a hardener and polyester vinyl ester resins use a catalyst usually mekp methyl ethyl ketone peroxide.
Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins.
Epoxy adheres to wood much better than polyester does.
The hardener catalyst for vinyl ester resin and polyester.
Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin.
Oz fluid ounce.
Resin has a short shelf life.
Vinyl ester resin cures with a tack.
Methyl ethyl ketone peroxide mekp is an organic peroxide used in the marine industry.
Mekp is also used with gel coats.
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.
It is the same catalyst used with polyester resins.
The speed of hardener chosen depends on the temperature in the.
Cloth and polyester resin.
Ve resin is a tougher resin because of its longer molecular chains.
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.
Catalyze 1 5 get a pint for a.
It can be used for corrosion fda applications smc repairs and even resin infusion.
It adds excellent strength rigidity adhesion water and chemical resistance.
When using vinyl ester resin be sure to use it quickly after purchasing.
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.
Using drops for catalyst measurement is only an estimate.
There is a choice of three different hardeners.
Catalyst chart for polyester resin gel coat and vinyl ester marine resins.
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.
To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.
It wets out glass very quickly and has low viscosity.
The hardener catalyst for vinyl ester resin is mekp methyl ethyl ketone peroxide.
The weight of mekp 925 is 1 125 grams per cc.
Fast medium and slow.
The styrene in the polyester or vinyl ester resin will melt it.
30 drops is approximately equal to one cc.
