Does anyone on the forum have any experience with SB-112 epoxy resin ? Thanks
SB-112 is good…
Resin Research is similar, but significantly less expensive…
Resin Research also has a sanding addative, as well as fast or slow hardeners…
You decide…
hasty reply, 'cos I have to get my tail to work about ten minutes ago -
used it for repairs, good enough stuff, dries/hardens very slow ( 12 hrs or more) in thin laminations, nice clear layup, works fine in general with other additives. Pricey stuff too. Shelf life is quite long.
Have had better results, or at least equal, with RAKA resin and their #350 non-blush hardener, and I am given to understand that greg’s Resin Research stuff is better still.
hope that’s of use
doc…
Thank You Doc and Paul for the quick reply and info.I was thinking of using Greg’s RR epoxy also .i have heard it is close to idiot proof.there is a board maker in my area that uses it i will try to get some from him. If I can not does anyone have a website ,phone number or e-mail address to contact Greg? thanks again
SB-112 is reasonable stuff but as stated above somewhat slow for most board building. It’s like our slow hardener in speed if you need that much time to work. We have a fast hardener which cuts times in half. Also Additive F makes everything work much easier on boards. No blush worries and sanding is much easier. Get in touch with us through or 321-223-5276 or 321-779-2369.
Thank You , I will be in touch on Thursday by phone.
I have used sb-112 for a couple of boards and agree with the assesments above.
I developed an allergic reaction to sb-112, its hardner has a different consitution to Resin Research’s and is known to be a big sensetizer, whereas Resin Research say they choose a low sensetizer formula. I therefore do not recommend using sb-112. I have been able to do some elaborate laminations on 2 boards since then plus a number of peel tests and blank glue ups using Resin Research without any further occurrences of the skin rash. I’ve also been taking extra precautions, but it makes sense to use the product which is known to be safer.
Thank you for the feedback,this forum is great for getting info .
I’ve used SB 112 and had that same problem (unable to sand). Then I found that you don’t have to wait for the epoxy to complete cure before doing finishing work on it (e.g., sanding). Use a good four way file (two size teeth each with a flat and rounded surface) to take down the rough spots as well as smooth it out quite a bit. You can actually get a near sanded finish with much less mess, waste, and time. Added bennie, you can save the filings and later mix them up with fresh epoxy to make a paste for repairs, filling in holes, etc.
