Product Detail

Product Introduction

High Conductivity Carbon Paste containing conductive carbon black CAS 1333-86-4 is a professional screen-printable conductive material developed for membrane keypad, membrane switch and flexible PCB production. The paste adopts high-performance carbon black raw material, which can form continuous conductive network after complete curing. It achieves stable low resistivity and maintains reliable conductive performance under frequent bending conditions.

The paste has excellent screen printing adaptability with moderate viscosity, good leveling property and sharp pattern edge definition. It can be well printed on PET and other flexible substrates. After curing, the coating owns strong substrate adhesion, outstanding flexibility and anti-cracking capacity. It will not easily cause resistance drift during long-term repeated bending, meeting the continuous working requirements of flexible electronic components. It is a mature conductive material for manufacturing consumer flexible circuits.

Core Advantages

Stable conductive performance. Formulated with CAS 1333-86-4 conductive carbon black, the finished conductive layer maintains low and stable sheet resistance.

Superior flexibility and bending resistance. The cured carbon film can withstand repeated bending without cracking or sharp resistance increase, perfectly matching flexible electronic applications.

Great screen printing performance. Suitable for conventional silk screen printing process, easy to form fine conductive lines, stable printing effect in mass production.

Strong adhesion to flexible substrates. Good bonding force with PET and common flexible base materials, avoiding peeling of conductive traces.

Consistent batch quality. Stable raw material formula ensures uniform electrical and printing properties between different batches.

Application Scope

This screen printable high conductivity carbon paste is mainly used for membrane keypad, membrane switch conductive circuits. It is also widely applied to flexible PCB conductive traces, touch switch conductive layers and other flexible electronic products that require screen printing conductive circuits.

Different printing thickness and curing parameters will affect final resistance value. Small sample testing is strongly recommended before formal mass production to confirm process parameters.

Usage Guidance

Select suitable screen mesh according to the width requirement of conductive lines. Stir the carbon paste evenly before printing to avoid sedimentation. Complete screen printing on cleaned substrate, then follow matched curing temperature and time specification to achieve target conductivity and adhesion. Adjust printing thickness and curing conditions to obtain required sheet resistance. Keep working environment clean to prevent impurities mixing into the paste.

Packaging and Storage

The carbon paste is packed in sealed containers to prevent solvent volatilization and contamination. Store in cool, dry and ventilated environment, avoid direct sunlight and high temperature. Keep container tightly sealed after taking materials. Under standard storage conditions, the product can maintain stable printing and conductive performance within shelf life. Do not mix with other types of conductive ink.
