CHARACTERISTIC AND USAGE

CHEERSIL 907M/907E/907DM/907DE Silane is a new type of coupling agent with reactivity and crosslinking ability. It can be hydrolyzed and react with moisture, alcohols, amines etc., so it is widely used in nature or synthesized rubber, resin-fiberglass composites as reinforcing agent and used as adhesive promoter in composite materials, coating, ink, adhesive and sealant etc. Specially, it is also used as end-capper for polyether, polyester or polyurethane prepolymer which are used for sealants or adhesives.

PACKAGING AND STORAGE

  • The product should be hermetically stored, because of its reactivity, it will be hydrolyzed, polymerized and then crosslinked by moisture .
  • Hermetically sealed stored in new iron drum with net weight 200KG.
  • A little stimulate skin and eyes, so it is necessary to dress appliances for labor protection when contacting it.
