Characteristics of ISK's electro-conductive materials

ISK's electro-conductive materials consist of antimony-doped tin oxide (ATO), which is an electron conductor. The materials show excellent conductivity and absorption of near infrared rays (heat rays).

The following four types of products are available.
ET series : White electro-conductive titanium dioxide, spherical type
FT series : White electro-conductive titanium dioxide, acicular type
SN series : Transparent electro-conductive materials, spherical type
FS series : Transparent electro-conductive materials, acicular type

Major applications: Conductive primer for electrostatic coating, Anti-static coating (building material, floor, film), Anti-static ink, Anti-static resin and fiber, Heat shielding coating (film), Thermal fiber

Application

Electro-conductive primer for electrostatic coating

An electrostatic coating on a plastic bumper needs an electro-conductive primer.
Even though a grey electro-conductive primer with carbon black is usually applied as an electro-conductive primer, a white electro-conductive primer with our white electro-conductive titanium dioxide works better for making a thinner white base coat film with enough opacity.

Anti-static coating

Example:
PCM coating, floor coating
Properties:
Excellent storage stability, chemical resistance, low humidity dependence, and color matching.

IR-shielding ability of SN-100P

Bellow graph shows transmittance curve of SN-100P coating.
Infrared rays are absorbed due to the plasmon absorption of free electrons of SN-100P.
