Key Functions

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

Applications

Silanes are used in a variety of industrial applications as:

• Adhesion promoters
• Coupling agents
• Crosslinkers
• Moisture scavengers
• Resin additives
• Surface modifiers
• Diamine functional silane that finds use as a coupling agent providing superior elongation, flexibility and spreading at the interface of polymers.
• Used to promote adhesion between resins that react with amino groups and the surfaces of glass, mineral, metal, etc.
• Suitable Polymers: Bulyl, Polyurethane (2K), Cellulosis, PVB, Epoxy, Silylated Polyether, Silylated Polyurethane, Nulamine, Silicone, Nitrocellulose, Polyamide, Polyether etc.
