Andisil® 1289 Silane

1 of 500 products in this brand
Bis[3-(triethoxysilyl)propyl]tetrasulfide, yellow-brown liquid appearance. Silanes are used in a variety of industrial applications.Organofunctional Silanes have an organic functional end group and an alkoxy functional end group which allow the silane to act as a bridge between organic materials and inorganic substrates. The organic functional group is matched to the resin system while the alkoxy group provides the reactive site for crosslinking. These materials are useful as adhesion promoters, crosslinking agents, surface modifiers and hydrophobizing agents.

Functions: Adhesion Promoter, Coupling Agent, Moisture Scavenger

Chemical Family: Organosulfur Compounds, Silanes, Sulfur-based Compounds

Compatible Polymers & Resins: Acrylics, Chloroprene Rubber (CR), Epoxies (EP), Isoprene Rubber (IR), Nitrile Butadiene Rubber (NBR), Styrene Butadiene Rubber (SBR)

Features: High Gloss, Improves Physical Properties, Mar Resistance, Slip Resistance

Synonyms: 3,3′-Bis(triethoxysilylpropyl) tetrasulfide, 4,4,15,15-Tetraethoxy-3,16-dioxa-8,9,10,11-tetrathia-4,15-disilaoctadecane, Bis(3-(ethoxysilyl)propyl)tetrasulfide, Bis(3-triethoxisilylpropyl)tetrasulfide, Bis(3-triethoxysilylpropyl)tetrasulfane, Bis(triethoxysilylpropyl)tetrasulfane, Bis[3-(triethoxysilyl)propyl] tetrasulfide, Bis[triethoxysilylpropyl] tetrasulfide, Bis[γ-(triethoxysilyl)propyl] tetrasulfide

Applications & Uses

Applications

Silanes are used in a variety of industrial applications as:

  • Adhesion promoters
  • Coupling agents
  • Crosslinkers
  • Moisture scavengers
  • Resin additives
  • Surface modifiers
  • Bifunctional, sulfur-containing organosilane for rubber applications in combination with white fillers containing silanol groups
  • Used to improve the physical properties of sulfur cured compounds and to establish the chemical link between rubber and silica or other active white fillers
