Polyurethane resin
Specialty PU resin for pour-in-situ seal ring

Anti-moisture rigid structure adhesive


Component:

WINNATE-302A

WINCURE-302B

 

Application:

·Used as pour-in-situ seal ring for proof of vacuum-loss, or fluid-loss for precise instrument.

 

Advantage:

·Easy to process and no need for method to prevent from moisture voids as that of common PU solution

·Non-additive added

·Good adhesion to various substrates

·Good flowability to fill in small gap

·Curable under room temperature

·High strength and tough
