Will 2-part epoxy melt?
Pure resin DOES NOT MELT. What happens is that the polymer chain starts to disintegrate when heat is applied to resin, as it is a thermosetting polymer. As the breakdown occurs, resin starts to soften. Many people often perceive this process as MELTING, when it actually isn't!
Is two part epoxy toxic?
The hardened, finished polymers are almost non-toxic; it is exposure to the uncured resin components that can be harmful. In a two-component epoxy product, the epoxy resin and the curing agent are packaged separately and must be mixed together just before being used.

What is resin made of?
The resin itself is made of bisphenol (and there is more than one type) and epichlorohydrin. The most common type of bisphenol is a combination of acetone and phenol. Maybe you’re asking yourself now: where on earth does phenol come from? Well, when it was first discovered it came from coal tar, but nowadays, chemists extract it from petroleum (like so many other useful compounds). Now as far as epichlorohydrin is concerned, well, it’s derived from something called allyl chloride, a chlorinated tub chemical of propylene.
How is epoxy resin made?
Epoxy resins produced from such epoxy monomers are called glycidyl -based epoxy resins. The hydroxy group may be derived from aliphatic diols, polyols (polyether polyols), phenolic compounds or dicarboxylic acids. Phenols can be compounds such as bisphenol A and novolak. Polyols can be compounds such as 1,4-butanediol. Di- and polyols lead to diglycid polyethers. Dicarboxylic acids such as hexahydrophthalic acid are used for diglycide ester resins. Instead of a hydroxy group, also the nitrogen atom of an amine or amide can be reacted with epichlorohydrin.

Why does epoxy yellow?
Significant advances in understanding yellowing of epoxies were achieved by Down first in 1984 (natural dark aging) and later in 1986 (high-intensity light aging). Down investigated various room-temperature-cure epoxy resin adhesives suitable for use in glass conservation, testing their tendency to yellow. A fundamental molecular understanding of epoxy yellowing was achieved, when Krauklis and Echtermeyer discovered the mechanistic origin of yellowing in a commonly used amine epoxy resin, published in 2018. They found that the molecular reason for epoxy yellowing was a thermo-oxidative evolution of carbonyl groups in the polymeric carbon–carbon backbone via a nucleophilic radical attack.
