Detailed Description

Typical Technical Data The below values are not intended for use in preparing specifications. Please confirm with us prior to writing specifications on this product. CAS NO.: 2768-02-7 EINECS NO.: 220-449-8 Appearance: Colorless transparent liquid Colour (Pt-Co): 25 max Specific Gravity (ρ20°C,g/cm3): 0.965~0.975 Refractive Index ( ): 1.3925~1.3935 Purity (by GC, %): 98.0 min Properties Pipes and cables produced from silane-crosslinked polyethylene (PE-Xb) using AC-271 are more resistant to heat and weathering than products made from non-crosslinked polyethylene. They also have improved electrical properties. The storage stability is greatly enhanced in formulations of silane crosslinking adhesives and sealants. Use of AC-271 as a co-monomer in polymer dispersions results in binders which exhibit much improved wet scrub resistance and higher abrasion resistance thanks to crosslinking and improved adhesion to the substrate. Application Silane AC-271 is an essential ingredient in many industries as below: Moisture curing of polymers: For the preparation of moisture-curing polymers Adhesion promotion & surface modification: As an efficient adhesion promoter for various mineral-filled polymers As co-monomer for polymer dispersions: Improve adhesion strength in wet conditions and scrub resistance As moisture scavenger: Can react rapidly with water Other applications: can easily bond with OH-group. Hydroxyl containing polymers; it is activated by its proximity to silicon
