Graphite varnish: description, properties, application

Universal conductive graphite varnish was created by specialists to restore and subsequently maintain optimal voltage indicators. Most often, the tool is used to repair conductors and contact groups of powerful remote controls, household appliances, tracks of printed circuit boards. Experts are accustomed to using graphite varnish for heating strands of automobile windows, as well as similar electrical systems.

Conductive adhesive

Description

The classic composition of graphite varnish includes special fine-grained components. Careful polymerization of all substances leads to the formation of a durable matte film with excellent electrical conductivity on the surface. The maximum effect of the use of the product occurs within an hour after varnishing. The next 12 hours, the result only intensifies. To achieve the best result, you can use reprocessing. Since the craftsmen varnish rather small surfaces, you need a minimum of funds to work. That is why everyone can buy graphite varnish. The solution is applied as accurately and accurately as possible.

Professional product

Important points

On sale you can find graphite varnish in the form of a spray, which is made on the basis of high-quality powder. The tool can be safely used to create conductive surfaces on glass, plastic, wood and metal. Some craftsmen use such a varnish to form a surface that is as smooth, moving, resistant to temperature differences as possible.

Shake well before use. Before surface treatment it is necessary to carefully clean from dirt and dust, degrease and dry. If the user has purchased a spray, then after operation, the valve must be wiped with a napkin to close the lid as tight as possible. It must be remembered that the substance has a certain toxicity and flammability, because of which it is necessary to adhere to elementary safety rules. It is better to work with varnish in a well-ventilated area.

Use of funds

The properties

Graphite varnish is easy to apply on any surface and adheres to work items as firmly as possible. Means even for glass. The varnish boasts excellent adhesion. Efficiency is maintained even when exposed to a temperature of +300 degrees. The product is painted in a characteristic black color. The use of graphite varnish is relevant in the case when it is necessary to protect from electrostatic discharges created equipotential surface. Masters use the tool in the repair of picture tubes, cathode ray tubes. In this case, damage to the conductive coating of the cone can be eliminated. Graphite varnish will also be relevant in the event that it is necessary to prepare for the galvanic coating those parts that are made of non-conductive materials.

DIY conductive varnish

DIY making

The classic conductive varnish is ideal for a powerful connection that provides electrical contact between different parts. The tool is actively used in various industries, because of which the craftsmen came up with a universal recipe, thanks to which you can make graphite varnish with your own hands. To do this, prepare:

  1. Super glue.
  2. Nitrocellulose glue.
  3. Graphite.
  4. A glass cup.
  5. Aluminum powder.
  6. File.
  7. Pliers.
  8. Zapon varnish.
  9. Glass stick.
  10. Metal mortar with pestle.

The first thing you need to do is graphite powder, for this the rods from ordinary 2M pencils are perfect. The tool is heated with a soldering iron. It is necessary to mix graphite powder well with zapon-varnish or glue. The mass must be stored in a tightly closed glass container. The tool is ideal for repairing damaged printed circuit tracks, as well as instead of traditional soldering of different parts. For applying funds, an ordinary drawing pen is ideal. Graphite can also be replaced with aluminum powder. Previously, all surfaces to be treated must be cleaned so that there is no contamination. Also, parts must be degreased. Otherwise, graphite varnish may not stick. It is worth noting that different conductive compositions can not boast of the same resistance. This nuance must be taken into account during installation.
