Anybody know where I can get a methacrylate resin for infusion?
What makes Methacrylate resins so good? Is it a solvent base resin?
Has anybody used any Methacrylate resins lately?
John, I’ve heard of the superglue formulations being used but haven’t investigated them yet.
I’m assuming your needing a particular resistance for this critical choice?
Not really. Spoke to the Scott Bader company at the Orlando composites show and they showed me chips of plies of carbon infused with methacrylate infusion resin. Had a higher TG, elongation, flex, impact, glass transition temp, etc, etc,than most epoxy systems. Also low post cure process and the parts can be post cured out of the mold with no warp. How much truth there was to that is beyond me. That’s why I ask. They sent me a sample a while ago but it went bad before I got to use it. Had to promote it myself, cobalts, etc… Never got around to buying the chemicals in time.
Ahh, I see. Not smart for them to expect you source promotion and have a good test.
yeah, that’s why I wasn’t so crazy about it and/or eager to try it out. I would much rather buy a resin, just simply catalyze it and go.
Its not so bad once you get used to it. I’ve been self promoting with Cobalt, then initiator for some time. Its just one more weighing step and mixing for really fresh product.
That is if you have the elements on hand.
Whats the reason to self promote and add your own cobalt? Perhaps the gel time, cure time, ramp to gel time? temperature?
I’m moving my operations from Miami to Chicago so I will be dealing with hot humid summers and cold dry winters. Is there any reason why I should want to promote my own resins?
Im guessing this is the resin you were shown in Orlando is it?

Yes sir. That sure is.
really interested to hear more about this resin too!
working with methyl-methacrylates in the dental setting I know that they tend to have a very large shrinkage and deformation as they cure… they can also exotherm quite aggressively not sure if this is comparable…
Are the dental resins not epoxy acrylates?
methacrylates can be used to replace styrene in polyester resin. I know we have or had a bunch, but I never worked with that.
If this resin from Scott Bader really works as described with out of mold post cure with no shrinkage,wouldn’t it be safe to classify this as a wonder resin?!
my chemistry is very rusty, you are right there are a lot of epoxy based acrylates used.
even when working on something as small as a filling in the tooth the shrinkage of these sometimes poses problems.
Replace wonder with unicorn and you’re about right.
