PU resin

  1. Nov 10, 2005 #1
    Dear group,

    Can anyone tell me what kind of material PU Resin is?

    Is resin a material or just a "spacification" of PU?

    A resin (in an engineering context) is essentially a viscous liquid which is capable of hardening. Commonly, you'll have heard of epoxy resins, (such as Araldite 2 part adhesive), which is supplied as a resin with a hardener. Upon mixing of the two, a polymerisation (addition or condensation, I can never remember) reaction occurs, the monomers crosslink, and the polymer is formed, for use as either an adhesive, or an engineering material.

    Polyurethane itself is any polymer which consists of organic units joined by urethane links.
