Dynasylan MEMO

3-Methacryloxypropyltrimethoxysilane

Dynasylan MEMO is a methacrylfunctional silane that can be used as adhesion promoter, surface modifier, co-monomer for polymer synthesis and crosslinker.

Key Features

Dynasylan MEMO is a clear, colorless liquid. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.

Recommended Applications

Dynasylan MEMO is used as adhesion promoter in application such as:

  • A constituent of glass fiber sizes (glass fiber fillers for unsaturated polyester resins and polyolefins)
  • A finish for glass fabrics used in unsaturated polyester resins
  • As a surface modifier for pigments and fillers for thermosets (unsaturated polyester, MMA), thermoplastics (polyesters and polyolefins)and elastomers
  • As an additive for filled, peroxide-crosslinked elastomers
  • As an additive for casting resins (unsaturated polyester, MMA)

 

Dynasylan MEMO is either applied to the inorganic substrate as a pretreatment by dipping, spraying, or coating or it may be added directly to the resin matrix (additive process). For pretreatment, the silane may be used

  • Neat
  • Dissolved in an organic solvent
  • Dissolved in a mixture of organic solvent and water for partial hydrolysis
  • Completely hydrolyzed in aqueous solution
