Knowledge Popularization——SIWAY Two-component Sealant for Insulating Glass

Today, Siway will introduce to you the knowledge of our two-component insulating glass silicone sealants.

First of all, the independent two-component insulating glass sealants produced by our siway includes:

1. SV-8800 Silicone Sealant for Insulating Glass

SV-8800 is two components, high modulus; neutral curing silicone sealant specifically developed for assembly of high performance insulated glass units as secondary sealing material.

Key Features

  • High Modulus
  • UV resistance
  • Low vapor and gas transmission
  • Primerless adhesion to coated glass
  • 100% compatible to SV-8890
  • Component A(Base) – White, Component B(Catalyst)- Black



2. SV-8890 Two-component Silicone Structural Glazing Sealant

SV8890 is a two-component silicone insulating glass sealant is neutral-curing insulating glass secondary sealant with structural capabilities.

The product formulation utilizes its high modulus and high strength properties to meet the requirements of insulating glass assembly. With its high modulus at short elongation it is especially designed for air- and noble gas-filled IG-units. 

Key Features:

  • None sag
  • Adjustable working time
  • Excellent adhesion to most building substrates
  • High bonding strength and modulus
  • 12.5% movement capability
  • Silicone durability


3. SV-8000 PU Sealant for Insulating Glass

SV-8000 is a two-component polyurethane insulating glass sealant is a neutral cure, mainly used for the insulating glass of the second seal. Product formulation to use its performance with high modulus, high strength, to meet the requirements of insulating glass assembly.

Key Features:

  • High Modulus
  • UV resistance
  • Low vapor and gas transmission
  • Primerless adhesion to coated glass


4. SV-998 Polysulphide Sealant for Insulating Glass

SV-998 is a kind of two-part room temperature vulcanized polysulphide sealant with high performance especially formulated for insulating glass. This sealant has excellent elasticity, heat gas penetration and adherent stability to various glasses.

Insulating glass is a kind of energy-efficient material with various functions of soundproof, heat-resistant,anti-frost,and anti-fumeetc.It is widely used as the wind shields in construction. trains automobiles and the door glasses in refrigerators and freezing cabins.


Their most basic application is the second sealing of insulating glass (as shown below).


These sealants offer many advantages over traditional one-component sealants and are an excellent choice for any construction project.


This issue of Siway news comes to an end, I hope you can know more about our two-component insulating glass sealants.
