Abstract:
An elongated member is provided in the discharge orifice of a spray head nozzle so that the fluid being sprayed is discharged as a hollow stream resulting inter alia in a better and more complete atomization of the fluid in coaction with a low pressure propellant.
Abstract:
The porosity and surface roughness of ceramic substrates are improved by coating the surface with silicon compounds, drying the coated substrate, and then subjecting the substrate to elevated temperature so as to convert the silicon compounds to silicon oxides. Coated substrates obtained by the above process as well as specific preferred organosilane compositions are provided.
Abstract:
EPOXY REMOVAL Cured epoxy compositions are removed from substrate by employing compositions containing an organic cyclic alcohol and a surface-active agent. E979-020
Abstract:
A hermetic topsealant for metal electrodes on components and other microelectronic circuitry is formed by polymerizing a mixture of an unsaturated silane monomer, a bifunctional silane adhesion promoter, a polymeric plasticizer and a stabilizer.
