Functional Materials
Electro-conductive Materials ET/FT/SN/FS Series
ISK’s electro-conductive materials use tin oxide as a major component. In addition to high electro-conductivity, these materials exhibit superb absorption of near infrared rays (heat rays).
Their major applications include floor paints for clean rooms which are sensitive to dust and static electricity and conductive paints that enable electrostatic painting of automotive plastic bumpers.
Grades are available in four series: white electro-conductive titanium dioxide (ET series), acicular white electro-conductive titanium dioxide (FT series), transparent electro-conductive materials (SN series), and acicular transparent electro-conductive materials (FS series).

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 (building materials and floors)
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.
