Features Of XIAMETER PMX-0156 Silanol Fluid

  1. Low-viscosity, linear silanol fluid offering excellent hydrolytic stability under neutral to mildly acidic conditions.

  2. High reactive silanol (Si–OH) content enables efficient condensation with silica surfaces and metal oxides.

  3. Non-volatile and non-foaming—ideal for precision coating and surface modification processes.

  4. Compatible with common organic solvents (e.g., isopropanol, toluene, xylene), facilitating easy formulation integration.

  5. Free of catalysts and ionic impurities—supports high-purity applications in optics and electronics.

Typical Applications Of XIAMETER PMX-0156 Silanol Fluid

  1. Surface hydrophobization of fumed and precipitated silica fillers in silicone elastomers.

  2. Priming agent for glass, quartz, and ceramic substrates prior to silicone or epoxy bonding.

  3. Stabilizer and coupling aid in colloidal silica dispersions and sol–gel coatings.

  4. Moisture-scavenging additive in RTV-2 and LSR formulations to suppress premature crosslink inhibition.

  5. Functional modifier for anti-reflective and self-cleaning thin-film coatings.
