Silquest™ A-1100 Features & Benefits

CASE Ingredients Features
Product Highlights
  • Secondary phenyl amino group reacts with such resin systems as isocyanates, acrylates, epoxies, phenolics and silicones.
  • Methoxy silane ester for fast hydrolysis time.
  • Aromatic amino group for increased stability of resin/silane bond at elevated temperature.
  • Phenyl group for good resin wet-out

Applications & Uses

Recommeded Usage
  • Coatings, Adhesives and Sealants : This amino silane is an excellent adhesion promoter to consider for use in many coating, adhesive, and sealant systems. With polysulfide, urethane, RTV silicones, epoxy, nitrile, and phenolic adhesives and sealants, the product can improve pigment dispersion and adhesion to glass, aluminum, steel and various other substrates.
  • Glass-Reinforced Resin Systems
  • Glass Fiber and Mineral Wool Insulation : As a phenolic resin binder additive, Silquest A-1100 silane coupling agent can impart moisture resistance and allow recovery after compression.
  • Mineral-Filled Resin Systems : Silquest A-1100 silane coupling agent can improve the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix can also be improved
  • Foundry Applications : In shell molding, this silane can strengthen the bond between the phenolic binder and foundry sand.
  • Grinding Wheels : The product can promote an improved, water-resistant bond between the abrasive grit and phenolic resin binder.
