STRUCTURAL SEALANTS

Structural Sealants

Structural silicone sealants are moisture curing polymers aka Room Temperature Vulcanise (RTV) adhesive that takes in the surrounding humidity to polymerize and form a tough, flexible, and temperature resisting rubber compound. These polymeric sealants are formulated with 1 or 2 component systems that will either cure with surrounding moisture or by way of a catalyst tin to form the polymerization effect. 

These specialised silicone sealants are widely accepted by the industries like construction, electronics, automotive, solar panel, glass and window installation, and many more applications that require structural sealing and bonding purpose. The cured properties are very robust due to its low Glass Transition Temperature (TG) that gives its flexible nature at ambient condition, high serviceable temperature resistance, anti-UV, good electrical resistance, and highly versatile for use due to its ease of application and cure condition. The types of structural sealants chemistries structural that is being widely used in the industries include

All these polymeric sealants when fully cured will yield high bonding strength, minimal shrinkage, and long-term durability when exposed to different environmental and operating conditions.

Vitrobond 1 Part Silicone Adhesive

Vitrobond 1 component silicone adhesive is formulated specifically for the purpose bonding of silicone to silicone rubbers and to metals or some engineering plastics using specialised primer as a catalyst. 

It is a known fact that no adhesives can bond silicone rubbers together strongly unless it is pre-treated with specialised primer to promote adhesion between silicone rubbers or silicone rubbers to metals or plastic substrates.  With specialised 1 component silicone adhesive, it will enable users from the manufacturing or assembly to consider using silicone rubber compounds in the product design and using the adhesive to provide strong bonding integrity. 

This 1 component silicone adhesive cures at room temperature that will provide excellent bonding strength to silicone and other related rubber compounds with good flexibility, electrical insulation and high service temperature resistance.  

  • Non-corrosive silicone sealant.
  • Bond strongly to silicone rubbers & low surface energy substrates.
  • Room temperature cure.
  • Good operating temperature of -60°C to +200°C.
  • Good electrical insulative property.

Typical industrial applications include:

  • Sealing of electronics and electrical boxes.
  • Seal of electrical connectors.
  • Holding and fixing electronic components.
  • Microinverter box bonding.
  • Sealing and bonding of electrical appliances. 

1 Part Silicone Adhesive:

  • Vitrobond SS3000 - Good electrical insulation bonding silicone adhesive. Withstand temperature up to +200°C
