GENIOSIL® XL 10

$GENIOSIL<sup>®</sup> XL 10

  • CAS No. 2768-02-7
  • Empirical formula C5H12O3Si
  • Molecular weight 148,23 g/mol

Properties

Pipes and cables produced from silane-crosslinked polyethylene (PE-Xb) using GENIOSIL® XL 10 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 GENIOSIL® XL 10 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.
GENIOSIL® XL 10 is an alkoxyvinylsilane. It´s a clear, colorless liquid with a characteristic odor. The silane hydrolyzes in the presence of moisture (methanol is released) to form silanols, which can then react with themselves to produce siloxanes.

GENIOSIL® XL 10 is used in the production of pipes and cables made of silane-crosslinked polyethylene (PE-Xb), as a water scavenger during the production of silane-crosslinking adhesive and sealant formulations, and as co-monomers in the production of silane-modified binders for surface coatings.



1. Grafting of GENIOSIL® XL 10

The radical grafting of GENIOSIL® XL 10 to polyolefins, such as HDPE and LDPE, is typically effected via reactive extrusion, using peroxides as catalysts. Usually, 1-2 wt % GENIOSIL® XL 10 is required, expressed in terms of the polyolefin. Polyolefins grafted with GENIOSIL® XL 10 are moisture-cured after molding.

2. GENIOSIL® XL 10 as an additive in silane-crosslinking formulations

In silane-crosslinking formulations, (e.g. silane-terminated polyethers , polyurethanes or polysiloxanes), GENIOSIL® XL 10 is mixed into the formulation as an additive to prevent premature crosslinking due to trace moisture. Processing is effected by means of standard mixing methods (e.g. paddle agitator, dissolver, kneader). GENIOSIL® XL 10 may be added before or during incorporation of the reactive polymer. The amount added will depend on the water content and pretreatment of the components

3. GENIOSIL® XL 10 as a co-monomer in polymer dispersions

To incorporate GENIOSIL® XL 10 in organic polymer dispersions by way of co-polymerization, it is added as as co-monomer - along with typically used monomers (e.g. ethylene, vinyl acetate, styrene, acrylate) and freeradical initiators (diazo compounds or peroxides) - during production of the emulsion polymer

Storage

The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
