Dynasylan® 1401

Dynasylan® 1401 is a bifunctional organosilane possessing reactive amino groups and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® 1401 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics and elastomers), thus functioning as an adhesion promoter, surface modifier and as a reactant for product modification. Dynasylan® 1401 is a clear yellow liquid with an amine-like odor. It is soluble in alcohols and aliphatic or aromatic hydrocarbons.

Product Applications

Dynasylan® 1401 can be used in many applications.
Examples are:

  • Additive for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while maintaining the shelf life of the resin over long periods
  • Starting material in the synthesis of amino-functional silicones
  • Additive to phenolic resin binders for mineral fiber insulating materials
  • Primer for additive to sealants and adhesives
  • Additive and/or primer for improving the adhesion of paints and coatings to the substrate

Important product effects that can be achieved through the use of Dynasylan® 1401 include:

  • Improved mechanical properties, e.g. strength, impact strength and modulus of elasticity
  • Improved moisture and corrosion resistance
  • Improved electrical properties, e.g. dielectric constant, volume resistivity

Dynasylan® 1401 can also improve processing properties such as

  • Adhesion

Product Reactivity
  • In the presence of water, the methoxy groups of Dynasylan® 1401 hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.
  • The organophilic diamino group of Dynasylan® 1401 can react with a suitable polymer.
  • The hydrolysis of Dynasylan® 1401 takes place autocatalytically.
  • The pH of the hydrolysate is about 10-11.
  • Dynasylan® 1401 may be used with such polymers as phenolic, furan resins and silicones.
  • Dynasylan® 1401 can undergo reactions with ketones or ester solvents.
  • The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates, respectively.
  • Product modifications are possible through co-condensation with polysiloxanes (textile auxiliaries).
