Brazing and Soldering Paints

More informationGet a quote

Tin and solder paint is a homogeneous all-in-one mixture of metal powder, stripping flux and binder. It is widely used in industrial environments, such as electronics, semiconductors, aeronautics, the automotive industry, railways, the construction industry, mechanical and electrical assemblies, etc. The use of this product guarantees precise dosing of the quantity of solder to be applied and saves time. If you’re looking for tinning or soldering paint, choose Metaconcept, which offers a product produced using an ecological and responsible process.

Why choose to use tinning or soldering paint?

Many industrial sectors need tin or solder paint. In the electronics industry, it is used for soldering surface-mounted devices (SMDs). It is used to cover the surface of the bare screen-printed printed circuit. During this stage, the paint is only applied to the locations where the electronic parts are terminated.

Once the paint has been applied, these parts are then deposited by special machines. The electronic board is then taken to an oven and subjected to a fairly high temperature in order to melt the tin solder paint and solder and fix the ends of the electronic parts. The heat applied to the board does not risk damaging it.

Using tin or solder paint has a number of advantages:

  • Practical: it makes it easy to remove and solder small electronic parts. All you need is a stencil to apply it.
  • Reduced surface tension of the solder, making it easier to apply to the areas to be soldered.
  • Holds components in place before soldering, thanks to the viscous properties of the tinning or soldering paint.

Characteristics of paint for tinning or soldering

Tin or solder paint mainly contains metal powder, stripping flux and a binder mixture. The metal powder consists of a tin-copper alloy with a particle size greater than 75 microns.

In addition to soldering electronic parts in the electronics sector, tin or solder paint is also used in other sectors. In the automotive industry, it is used for mechanical and electrical assemblies.

The choice of paint depends on the application. For assembling copper, steel, brass or copper alloy components, use tinning pastes made from 30%, 40% or 60% tin and lead.

For assembly work on various types of metal other than aluminium and lead-free alloys, tinning paint containing 97% tin and 3% copper is recommended. Finally, 100% tin-based tinning paste is used for all types of metal except stainless steel, aluminium and lead-free alloys.

The melting temperature of tinning or soldering paint is +245°C. When using it, we recommend that you wear personal protective equipment (gloves, shoes, hard hat and safety goggles, etc.).

Recycling, a sustainable solution to avoid depleting metal resources

When it comes to tinning and soldering paints, metaconcept is the best choice. This French company, which specialises in non-ferrous alloys and associated stripping fluxes for a variety of industrial uses, offers customers a sustainable solution to prevent the depletion of natural resources.

Metaconcept’s tinning and soldering paints, like its other products, are derived from a recovery process. Tin is a metal that can be recycled ad infinitum. Tin-based waste generated by industry is collected, sorted and recycled before being reused.

So if you care about the environment and the planet, choose Metaconcept tin or solder paint. Get more information about our products by contacting our engineers.
