Touch-Up Paint Pens for Metal

Prep, paint, and seal small scratches on metal surfaces with these pens.

Black pens have a beveled abrasive tip to remove rust and clean the surface. They have a roller-ball tip for precision paint application and a brush tip for general use. Once the paint dries, use the foam tip to apply the clear coat included in the pen’s base.

Conductive Surface Fillers for Electronics

A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. Product regulations restrict sales to the listed jurisdictions/areas.

Surface filler in a pen dispenses as a thin, ready-to-use liquid that fills in pitting and small gaps. It’s often used on circuit boards to fix components or to prototype new systems.

Volume resistivity and surface resistivity measure how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
