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 applications. Derakane Momentum resins are a new generation of resins that can be used to improve fabrication efficiency and product quality. Their lighter color makes defects easier to see and correct while the resin is still workable. The resin's improved reactivity properties often permit and increase in the lay-up thickness per session. The longer stability provides additional flexibility to fabricators in storage and handling. Resin: Color may vary by manufacturer.

MEKP Catalyst is very dangerous to the eyes. Always wear full goggle protection and have running water at hand when working with MEKP.

Works just as well as our old product we use to get. A great price per gallon on the shipping!

Great product for use on the Glasair I am building. Consistent Pot Life after catalyzed. Resin comes pre-promoted in the quart sizes. Easy to use.

Ive always received resin orders promptly, and they are well packaged to prevent spillage or odors. The only annoyance (which Aircraft Spruce may have limited control over) is the cost of shipping, which seems high. It is hazardous material, so I understand the issue. However it does provide me with incentive to search more locally for a compatible product.

Used the Vinyl Ester to do repairs on my engine plenum as the plenum was made with Vinyl Ester. Prior to this I have only used West Systems. One of the good things about this product is you can vary the curing time depending on how much MEKP you add. It mixes up quickly and brushes on very well. With the West systems I usually draw out my shape on sheet plastic and wet out the layers between two layers of plastic till it is all wetted out. Then I cut the shape, remove the plastic and put the glass in place. That will work with Vinyl Ester, but it tends to react with the plastic and start curling up the plastic sheet while trying to cut it to the shape you have traced out. Not a big deal, but it is definitely a different animal than the West Systems. MEKP has all sorts of dire warnings while using it, but Ive been using drops of it and found it to be a non event mixing it up. You will definitely want to use this in a well vented area. I finally started using a respirator as the odor is very strong. All in all it did what it was supposed to do. John

This product was no good. The gel time is triple what it should be. It’s ether old or not promoted properly

Q: Is this suitable for use with auto gas, which may contain alcohol?

Vinyl Ester is chemical resistant, and can be used to make fuel tanks to hold auto fuel, which can contain alcohol. Making a test piece is always recommended.

Q: What is included in the vinyl ester resin kit? Do I need to order catalyst separately? When I click on mekp catalyst, it brings up polyester resin. Thank you, Darrell

The items listed on this page are Vinyl Ester Resin only in quart or gallon size. If you would like to order the kit which includes the MEKP catalyst, please use part number 01-01109 (Qt Kit) or 01-07355 (Gal Kit). The links to these parts can be found in the "Alternate Items" tab.

Q: Does the resin come already promoted so all I need to do is add MEKP to the amount of resin that I need for the job? I already have DMA and Cobalt available for promotion and I certainly don't want to add any to the resin if it's already promoted.

All our stock vinyl ester resin is promoted, so only requires the MEKP to catalyze it. Un-promoted material is rarely requested, but can be sent as a special order only. Please contact sales at 877-477-7823 for special orders.

Q: Your chart for amount of catalyst is based on number of ounces of resin to be used. QUESTION - Are the ounces listed, volume - or - weight?

The mix ratio is by volume. You can mix it 1% to 2% by weight. The higher percentage by weight accelerates the pot life.

Q: For a non structural part what is the max temperature this vinyl ester resin can withstand?

The max temperature this resin can withstand is 220 degrees F.

Q: Does a hazardous material shipping charge apply when shipping Vinyl Ester Resin?

If shipping via ground, there is no hazardous shipping charge. If shipping via air, then yes, a hazardous fee will apply.

Q: Do you sell a resin pump that will fit these containers?

The west system pump will fit and pump the resin from the container. They will not have the same ratio though so you could not use them to portion out product, they would only be used to pump the resin from the container.
