Application introduction

Most coatings are organic polymers. After forming the coating, they are an insulator material. Under the action of high-voltage and strong DC electric fields, a strong electrostatic field will be generated. If a large amount of static charge accumulates on the insulating material, the electrical equipment will become unusable. For this reason, antistatic coatings came into being. Generally , coatings with surface resistivity between 10 ⁶ ~ 10 ⁹ Ω·cm ^-2 and volume resistivity between 10 ⁵ ~ 10 ^{8 Ω·cm are called antistatic coatings, which can quickly conduct current and eliminate static charges.}In the field of powder coatings, it has always been a difficult problem to reduce the resistivity of the coating and achieve stable antistatic and conductive properties.

Currently, there are many conductive additives on the market, including common carbon black, conductive mica, conductive titanium dioxide, etc., which have problems such as high addition amounts, single coating color selection, and unstable electrical properties.

TUBALL MATRIX 821 products

introduce

TUBALL MATRIX 821 is a single-walled carbon nanotube-based concentrate designed to provide excellent electrical conductivity to epoxy, polyester resin and polyurethane systems while maintaining mechanical properties and minimal impact on the bulk.

The TUBALL MATRIX 821 product developed by OCSIAL can provide conductivity at ultra-low dosage. By extruding and adding 0.1-0.3%, it can meet the requirements of 10 ⁵ Ω·cm to 10 ⁸ Ω·cm. It is easy to use and customers can complete it independently.

Key advantages of TUBALL MATRIX 821 products

introduce

TUBALL MATRIX only needs to be added directly during the premixing stage without changing the processing technology.

Full range resistivity, test results of two customer samples: antistatic powder coating surface resistivity 10 ⁸ Ω·cm and surface resistivity 10 ⁵ Ω·cm.

The conductive parts produced can retain bright colors. TUBALL single-walled carbon nanotubes can produce white and colored coatings while providing good conductive properties.

Maintaining mechanical strength, the data shows that neat powder coatings have the same properties as antistatic powder coatings, such as adhesion, impact resistance and cupping tests.
