Multi-layer anti-oxidation, anti-corrosion, and insulating coatings help solenoid bobbins withstand 1000°F and resist corona discharge.
Layered anti-oxidation, anti-corrosion, and insulating coatings help solenoid bobbins withstand 1000°F heat and resist corona discharge.
A higher-porosity region around the through conductor relieves thermal shrinkage stress while an outer dense layer blocks corrosion and solder burst.
Zinc silicate primer and polysiloxane layer prevent core corrosion in harsh environments through galvanic inhibition.
