XIAMETER® Silicones Simplified - from Dow Corning


XIAMETER® brand Silanes

Silanes



Silanes can be used as:

Silane
  • Coupling agents to bind organic polymers to mineral or siliceous fillers, resulting in improved mixing, bonding and strength
  • Crosslinking agents to improve a polymer’s resistance to tears and abrasion
  • Adhesion promoters
  • Hydrophobing (water-proofing) and dispersing agents
  • Water scavengers to capture excess moisture/prevent premature curing
  • Polypropylene catalyst “donors”

Advantages of Silanes


XIAMETER® silanes are extremely versatile, helping to improve:

  • Mechanical strength
  • Electrical properties
  • Moisture resistance in polymers
  • Water repellency
  • Adhesion
  • Compatibility
  • Dispersion of pigments, minerals and fillers
  • Polymer yield

 

Composition of Silanes
 

 Silane Composition  

Silanes are the basic building blocks of silicone chemistry. A silane is a monomeric silicon compound with the chemical formula:

R1, R2, R3, and R4 represent the four chemical groups attached to the silicon atom. These groups can be nearly any combination of non-reactive, inorganically reactive, or organically reactive groups, making silanes extremely versatile.

XIAMETER silane subgroups

XIAMETER organosilanes are available with a range of reactive and non-reactive functionalities. Reactive organosilanes include amino, chlorine, epoxy, melamine, methacrylate/methacryl, sulfur and vinyl silanes – which act primarily as adhesion promoters and surface treatments. Non-reactive organosilanes such as methyl, isobutyl, n-Octyl and phenyl silanes provide hydrophobicity (water repellency), silicone synthesis and, in the case of phenyl silanes, thermal stability to other silanes.

The primary applications of chlorosilanes are the synthesis of silanes and siloxanes, and as protecting agents for intermediates in pharmaceutical syntheses. XIAMETER® brand offers several chlorosilanes, so you’re sure to find one that meets your needs.

Methyl siliconates react with carbon dioxide to form breathable, water-insoluble silicone resins. Methyl siliconates are used to formulate penetrating, low-VOC water repellents. Silazanes are hydrides of silicon and nitrogen that have a straight or branched chain of silicon and nitrogen atoms joined by covalent bonds. They are analogous to siloxanes, with -NH- replacing -O-.
