Role of monomers in polester based polyurethane adhesives

01 January 1970 1 1K Report

There is many polyurethane adhesives. 2k and 1k adhesives. Polyester polyols are most useful raw material for polyurethane adhesives.

Many monomers can be used in this polyols including IPA, AA, DEG, EG, NPG and others.

What is the most obvious role or function o each monomer in pokyester polyols?

For example IPA for heat resistance? NPG for adhesion or hydrophobic behaviour?

Emilio Malaguti

Adhesives have the main function of creating a bond of the polymers to various substrates;

the characteristics of the polymer carrying the OH group depend on the monomer and in turns, will determine the final Tg, mfft, tack, dry-time, crosslink density and so on.

choose the monomers accordingly
