Detailed Product Description

Description
ZJ-8000 Silicone Structural Sealant is a two-part, neutral curing silicone formulation
specifically developed for the structural bonding of glass, metal and other
building components with good features as follows:
1. Approved by silicone SSG leading group of national committee of economic and trade
2. Meets National standards of GB-16776-2005
3. Excellent adhesion to a wide range of curtain-wall materials such as coated, enameled
and reflective glass, anodized oxidation or coated aluminum and stainless
steel.
4. High level of mechanical properties with joint movement capability of ±12.5%.
5. Neutral cured, no corrosion, non poisonous
6.Excelent stability in a wide range temperature at -50^oC~+150^oC
7. Excellent weatherproof feature and a high resistance to UV radiation, high temperature
and humidity.
8. Lot matching of base and curing agent not necessary. Structural applications require
prior testing and written print review by ZHIJIANG.
 

Where to use

USE LIMITATIONS

ZJ-8000 could not be used for structural curtain wall glazing before written certification of Zhijiang technical service department. Every project need single audit and approve by zhijiang. Project audit includes:

a.Joint size and design audit;

b.Adhesion and compatibility tests among materials;

c.Observe special structural application and working quality standard.

d.Zhijiang will not burden the responsibility for application claims caused if no certification of zhijiang technical service.

e.Zhjiang will issue quality insurance certificate to audited project. Users should conform local construction rules.

f.ZJ-8000 should not contact with any acetic sealant. Not recommend for drug use before tests.
