Stepan introduce new aliphatic polyester polyols as countertypes to popular grades on the market
We are delighted to announce Stepan have awarded Alfa Chemicals distribution of their polyester polyols covering the UK & Ireland for the CASE market. At the same time, Stepan have launched a new range of Stepanpols® aliphatic polyester polyols as alternatives to popular grades on the market. The range includes a variety of hydroxyl values and viscosities so we can easily match your commercial grades.
| ||Hydroxyl value mg KOH/g |
|Stepanpol® PC-020-01 ||20 |
|Stepanpol® PC-030-01 ||30 |
|Stepanpol® PC-030-03 ||30 |
|Stepanpol® PC-125-01 ||125 |
|Stepanpol® PC-130-01 ||130 |
|Stepanpol® PC-160-01 ||160 |
|Stepanpol® PC-165-01 ||165 |
Stepanpol® PC-130-01 & Stepanpol® PC-160-01 are polyester polyols primarily used in concrete primers where Stepanpols® show excellent attributes for bonding with good hydrolysis resistance and weatherability and good adhesion to many substrates. Stepan have carried out extensive testing on Stepanpol® PC-130-01 & Stepanpol® PC-160-01 and can show:
- 2K primers formulated with Stepanpol® demonstrate better mechanical properties & higher bond strength than with commercial standards available on the market.
- How working time & tack-free time can be controlled by isocyanate selection.
Reactive hot melts with very fast setting properties can be made with Stepanpol® PC-020-01. Open-time is shortened, melt viscosity is lower and initial bond strength is increased.
