 Midheaven Glass Using Butyl Sealant

Introduction

         YX-997 butyl sealant is a national “Plan” scientific and technological projiects.The product has 

excellent resistance to high tempetature effects,water,air tightness and resistance to UV aging 

characteristics,a variety of metal,glass,ceramics and other materials have good adhesion.

Temperature is 110°C~150°C, the main technical performance close to the international level

 of similar materials . It is dedicated to the Road sealed insulating glass.By it and the YX-886 sealant ,  YX-667 sealan ( for sealing insulating glass hereticssupporting  the  production  of  insulating glass to fully meet the national standard JC / T914-2003 .
