Evonik Dynasylan 1175 Cationic Aminosilane

Evonik Dynasylan 1175 is a cationic amino-functional silane combining vinyl reactivity with hydrolyzable methoxy groups. This 40% active solution in methanol enables robust bonding between inorganic substrates and organic polymers, offering unique antistatic and wetting properties.

Features Of Evonik Dynasylan 1175 Cationic Aminosilane

  1. Dual Reactivity – Features vinyl and amino groups for broad polymer compatibility

  2. Cationic Nature – Provides inherent antistatic properties and excellent resin wetting

  3. Instant Water Solubility – Fully miscible in water even at neutral pH

  4. Extended Gel Time – High chloride content delays epoxy curing, reducing air entrapment

Typical Applications Of Evonik Dynasylan 1175 Cationic Aminosilane

  1. Fiber Reinforcements – Glass fiber sizing for epoxy and unsaturated polyester composites

  2. Adhesive Systems – Primer and additive for sealants and adhesives

  3. Conductive Coatings – Antistatic modifier in paints and protective coatings

  4. Mineral-Filled Composites – Pretreatment agent for fillers and pigments

  5. Electronics Encapsulation – Enhanced dielectric properties in epoxy potting systems
