jumping on a dead horse, but for those interested:
"polymers" is a vague description for material made up of large molecules (many monomers). "resin" is a vague description for material made up of large molecules (yes, they can be manufactured polymers but can be natural materials as well).
"resin" can refer to a material that provides a binding property for a mix of chemicals that may not bind properly without it. it can also refer to a material that is used to make plastic products like action figures for example.
"polymers" can refer to a material that has long, interlocking molecular chains as in sealants and also "resins."
and for kicks, "solvent" usually refers to a material that acts as a carrier. polymers, solvents, wax, etc is mixed and carried in suspension by the solvent, and the solvent usually evaporates during drying, leaving only the polymers, resins, etc.
it is very likely different manufacturers use these terms in different ways.
i don't work for an automotive product company, but am an ex-chemical engineer and used to design and troubleshoot processes to manufacture specialty and commodity chemicals. and i'm very bored at work now sitting on a long conference call.
