WebThe effect of a nanometer confinement on the molecular dynamics of poly (methyl phenyl siloxane) (PMPS) was studied by dielectric spectroscopy (DS), temperature modulated DSC (TMDSC) and neutron scattering (NS). Nanoporous glasses with pore sizes of 2.5–20 nm have been used.
WebSilicone resin. Silicone resins are a type of silicone material which is formed by branched, cage-like oligosiloxanes with the general formula of R n SiX m O y, where R is a non reactive substituent, usually Methyl (Me) or Phenyl (Ph), and X is a functional group Hydrogen (H), Hydroxyl group (OH), Chlorine (Cl) or Alkoxy group (OR). sigma chi st thomasWebThese materials are oligomeric alkoxysilane hydrolyzates and are the basis of coating resins. They can also be used as primer coatings or to modify organic resins such as polyesters. They generate small amounts of alcohols as byproducts during cure.
