What is PU Resin? Is It a Material or Specification?

[temujin]

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.

PU Resin, also known as polyurethane resin, is a type of polymer material that is often used in the production of various products such as coatings, adhesives, and foams. It is created through the reaction of polyols (alcohols with multiple hydroxyl groups) and diisocyanates (compounds with two isocyanate functional groups). The resulting material is a versatile and durable plastic that can be molded into different shapes and forms.

To answer your second question, PU Resin is both a material and a specification. As a material, it is a type of polymer that has specific properties and uses. However, it can also be considered a specification because it refers to a specific type of resin that is made from a specific combination of polyols and diisocyanates. Other types of resins, such as epoxy resin or polyester resin, have different chemical compositions and properties. Therefore, PU Resin is both a material and a specific type of resin within the larger category of polymer materials. I hope this helps clarify your understanding of PU Resin.
