Q: After opening, what are the components shelf life? Anyway to lengthen their viability?

Bought some of this same brand/same size "at least" 40 years ago! It was kept (unfortunately) in my garage (NO HEATING OR AC) for most of this time... temps here can range anywhere from a low of 12 degrees. F to 105 degrees during the course of what one could consider a "typical" year. To my EXTREME SURPRISE...This stuff worked great up until LAST YEAR!!! The resin now appears to show some signs of "separation", but even still... if I take time to assure the resin is stirred in the bottle to a consistent appearance before dispensing, it will still harden and secure the items I use it on. It takes longer to reach a full cure than in the past, but works for my non-critical needs. I can't comment on whether it has the same total bonding power as when new, but it DOES still bond! I am however now finally buying a NEW set so that I can put projects in service based on the product's original "full bonding time frame" (mine takes longer now), and for items that are either too difficult access at will (for a potential re-do") or too critical in function to take chances with bonding failure. GREAT PRODUCT provided they haven't monkeyed with the formula since I bought mine! Even drinking water has a "shelf-life", so I'm totally amazed this stuff has performed so well during the 40 years or so I've had it!!!

Q: Will it melt blue styrofoam

No, it does NOT melt Styrofoam. I just tried it out, I can actually mix the two components while using white Styrofoam as a substrate. Not a trace of melting when doing so. Since blue Styrofoam is still Styrofoam but with a dye added, I am pretty sure it won't melt blue Styrofoam either.

Question 1

I'm really looking for something equivalent to super glue but in this size bottles.  Question is do need to use and mix both bottles for it to glue?

Accepted Answer

need to use equal parts of each tube, mix well. drying time will be stated on tubes, depending on type you buy...30 sec. to 30 min. or more. usually acetone clean-up before dried, acetone soak will also release bond, as will heat over 325 degrees.whatever quantity needed will still be a 1-1 mix, but keep in mind working time vs dry time, so not to mix more than you can use before hardening.  denatured alcohol can thin mixture

Question 2

Two questions: Is the mix pourable, and what is the maximum temperature that the cured resin can tolerate?

Accepted Answer

After mixing, the mixture is viscous but can still be poured (immediately). Maximum temperature before release of toxic fumes is <200 F, which is also the softening point for it's surface or glass tension stability, and higher temperature results in thermal decomposition and strength failure.
