Dynasylan® 9116

Dynasylan® 9116 is a monomeric long-chain alkylfunctional silane.
Dynasylan® 9116 is a clear colourless liquid and soluble in common organic solvents (e.g. ethanol, iso-propanol). However its low volatility and viscosity make Dynasylan® 9116 an easy-to-handle additive. During the hydrolysis reaction between water and Dynasylan® 9116 a certain amount of methanol (VOC) is released.

Typical Applications

Dynasylan® 9116 is a bifunctional organic compound in which the functional silanol groups can be bonded to an inorganic substrate and the organophilic alkyl group can interact with a suitable polymer.
Examples of suitable inorganic substrates are:
  • mineral fillers like, e.g. quartz, wollastonite or ATH
  • inorganic pigments
  • concrete

The organophilic long-chain alkyl group of Dynasylan® 9116 can interact with non-polar polymers like, e.g. polypropylene.
Dynasylan® 9116 finds application in the products of many industries. Examples are:
  • as a pretreatment or an additve to mineral-filled thermoplastic compounds
  • as scorch retardant in wire & cable production
  • as an additive for adhesives and sealants to improve adhesion to the substrate

Benefits at a glance

Because of its unique long-chain alkyl functionality, Dynasylan® 9116 exhibits superior hydrophobicity on substrates, excellent compound properties and forms weather- and moisture-resistant bonds to substrates as well. Use of Dynasylan® 9116 silane results in:
  • better dispersion allowing highly-filled compound formulations
  • enhanced mechanical properties, e.g. improvements in toughness in wollastonite-filled polypropylene compounds
  • waterproofing by impregnation when used as a water-repellent
