Effect of Silicone Conformal Coating on Surface Insulation Resistance (SIR) For Printed Circuit Board Assemblies

Conformal coatings are considered a method of providing corrosion protection to electrical assemblies used in high-humidity or harsh environments. They are applied to PCBs for various reasons: to protect from moisture and contamination, to minimize dendritic growth, to provide stress relief, and for insulation resistance. These contribute to more durable handling, enhanced device reliability, a...

A novel preparation method for silicone oil nanoemulsions and its application for coating hair with silicone

BACKGROUND Silicone oil, as a major component in conditioner, is beneficial in the moisture preservation and lubrication of hair. However, it is difficult for silicone oil to directly absorb on the hair surface because of its hydrophobicity. Stable nanoemulsions containing silicone oil may present as a potential solution to this problem. METHODS Silicone oil nanoemulsions were prepared using ...

Optimal Surface Coating

The short-term clinical failures of cementless stems, such as proximal bone resorption and thigh pain, have limited their acceptance despite the potential long-term benefits of biological fixation for younger and more active patients. The clinical problems are believed to be related to failure at the bone-stem interface. By optimizing the design of the prosthesis to prevent or minimize failure ...

Implant infections and antibiotic-impregnated silicone rubber coating.

A method is described for coating silicone rubber-encapsulated implant devices with an outer layer of silicone rubber impregnated with a mixture of gentamicin sulphate and diethanolamine fusidate. A coating of this sort provides bactericidal activity lasting for a few days in the film of fluid surrounding such an implant. When used for coating our implants, the retrospective rate of implant inf...
