silane Chemistry and Effects

Organofunctional silanes are hybrid substances which combine the functionality of a reactive organic group with a hydrolysable alkoxy group in only one molecule. (see image). This special property allows their use as molecular bridges between inorganic materials and organic polymers.  

Silane Benefits:

  • Increased adhesion to certain substrates
  • Improved moisture and chemical resistance
  • Increased abrasion or scratch resistance
  • Improved filler dispersion
  • Water repellency
  • May act as crosslinking agent in special coatings

  • Increased adhesion on various substrates
  • Improved storage stability by acting as moisture scavengers
  • Crosslinker for moisture-cured adhesive systems
  • Improved chemical resistance
  • Improved physical and mechanic properties of highly loaded formulations

  • Optimized adhesion to active fillers and therefore improved processability
  • Higher crosslinking density and improved mechanical properties
  • Reduced abrasion
  • Improved dynamical properties
  • Lower compression set
  • Improved electrical properties
  • Excellent dispersion and dosage as well as storage stability of our silanes on carrier systems

  • Optimized filler adhesion and dispersion
  • Improved compound processability
  • Special peroxide blends enable grafting onto polyolefins
  • Customer-specific blends allow for individual systems

   

Production of Silane Blends with Special Properties

In regards to specific properties, such as amplified  water repellency, increased flash point, VOC reduction or reduction of toxicity, blends of different silanes and additives can bring the desired effects. DOG produces numerous silane blends at its Marschacht site, either under its own name brand – as Deolink EH – or as customer-specific mixtures.
