EXCESTAR <General Name > Silane Modified Polyether
Product summary
This is a moisture hardened modified silicone polymer with a hydrolyzed silyl group on the end, and developed based on ultra high molecular weight polyether polyol (Preminol) technology.
It hardens due to moisture in the presence of a catalyst to become a flexible elastic medium. It is used as a base polymer for sealing materials, adhesives, etc.
Features
Excestar is a groundbreaking moisture hardened liquid polyether polymer with a hydrolyzed silyl group on the end, and developed based on AGC Chemicals' ultra high molecular weight polyether polyol (Preminol) technology.
It hardens due to moisture in the air in the presence of a catalyst to become an elastic medium.
Excestar has physical properties suited for sealants and adhesives by mixing with various types of fillers.
You will be able to obtain an elastic medium.
General name: sealant polymer adhesive polymer

Hardening properties
Because the ES-S series has a hydrolyzed silyl group on the end,
hardened material with excellent flexibility and elasticity can be obtained by moisture.
Standard hardening properties are shown below.
| Properties | 50%-Tensile Stress (N/mm2) | Maximum Tensile Stress (N/mm2) | Rupture Elongation (%) |
|---|---|---|---|
| ES-S2410 | 0.08～0.15 | 0.30～0.80 | 300～500 |
| ES-S2420 | 0.15～0.25 | 0.40～0.90 | 200～400 |
| ES-S3430 | 0.25～0.35 | 0.30～0.80 | 100～300 |
| ES-S3630 | 0.25～0.35 | 0.40～0.90 | 200～400 |
