Andisil® 6021 Silane

Adhesion Promotion:

• Low use levels, typically <1%
• Substrates - reaction with alkoxy functional group
  • Glass
  • Siliceous Substrates
  • Metals/ metal oxides
• Substrates – reaction with organic functional group
  • Acrylics
  • Polyamides
  • Polyesters

Coupling Agent:: 

• Dispersed in adhesive/ sealant material
• Improves
  • Mechanical Properties
  • Chemical Resistance
  • Hydrolytic Stability
• Substrates
  • Mineral fillers
  • Polymeric coatings

Crosslinking: 

• Create structure in polymer network
• Improve physical properties
  • Heat resistance
  • Hardness
  • Chemical Resistance

Dispersing Agent:

• Improves filler wetting
• Decreases viscosity which allows for high loading of silica

• Used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or siliconepolymer or as crosslinker (moisture crosslinking of polymers).
• Used as a coupling agent leads to in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.
• Soluble in alcohols and aliphatic as well as aromatic hydrocarbons.
• Maximizes the physical and electrical properties thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.

Andisil® 6021 Silane is available in 440 lb. drums or 40 lb. pails. Other packaging options may be available upon request.

The shelf life, when the container is stored unopened and under proper conditions above 50 ºF, is expected to be a minimum of two (2) years.
