Frequently Asked Questions

Q: Is the BISCO EC-2130 electrically conductive?

A: Yes, the EC-2130 is electrically conductive, which allows it to absorb and reflect EMI/RFI energy. It has a volume resistivity of over 10^13 ohm-cm.

Q: What is the recommended thickness for the EC-2130?

A: The recommended thickness is 0.5mm to 3mm. Thicker coatings generally provide greater shielding effectiveness.

Q: Does it require mixing before application?

A: No mixing is required. The EC-2130 is a single-part silicone that can be dispensed directly from the package.

Q: What type of surface preparation is required?

A: Surfaces should be clean and dry prior to application. Light abrasion can help improve adhesion. Primers may be used for some substrates.

Q: What is the shelf life of the EC-2130?

A: When stored properly in unopened containers at temperatures below 27°C, the shelf life is 1 year from date of shipment.
