Here are some paint strippers advertised as non-toxic, green and environmentally friendly. They are products for private, hobby or semi-professional use, freely available online together with the safety documentation used to draft the article.

Solvents or air bubbles present in the substrate degas during the paint reticulation (especially using paints with high percentage of dry residue), causing small holes and defects. The problem can be solved by heating the items in the oven prior to painting, in which the air or solvents contained are removed.

This chapter presents the most common tests to evaluate the physical resistance of coating films. Such mechanical tests are usually conducted in parallel with corrosion tests. The mechanical resistance provides an idea of: paint reticulation, paint adhesion to the substrate, anomaly relating to the pretreatment.

Powder paint is a coating which is applied in the form of dry powder by means of electrostatic spray guns that, by loading the paint particles, attracts them towards the product to be painted which is connected to an earthing system. Powder coating is a very widespread technique and it is used in various sectors such as aluminum extrusions,...

Flash rust

The "flash rust" is a very rapid corrosive phenomenon that can occur after cleaning, sandblasting or washing a ferrous product.

Surfactants

The world of surfactants is so vast and well-known that it would be useless to reproduce it entirely in this blog, we will therefore briefly illustrate the most important types and characteristics of the surfactants commonly used in the industry for the treatment of metals.

Corrosive tests, or corrosion resistance tests, are procedures designed to induce the corrosion of painted and unpainted products to verify their resistance in the short term. These tests represent empirically but reasonably the effects that natural corrosion would have over many years. To make these tests possible, painted specimens are placed...

Almost always, where there is an industrial pretreatment, there is also a painting. And where there is a liquid painting there can be a water management system.
