Deformulation of varnish in the laboratory
Your need: carry out the reverse engineering of a varnish and determine its chemical composition
What is a varnish?
First of all, before discussing the reverse engineering of a varnish, what do we mean by varnish? A varnish is a more or less viscous liquid formulation used to protect, tint, or enhance the surface of an industrial product. It is mainly made up of a natural or synthetic resin in solution or dispersion in a vegetable or mineral medium.
In addition, varnish has several characteristics such as transparency, gloss, and resistance. These vary depending on the resin originally used.
In what context should a varnish be reverse engineered?
Varnishes are made up of complex mixtures. The reverse engineering of varnishes consists in determining, through various chemical analysis;
- the nature of the components of this mixture
- the quantities of materials present in the varnish formulation
The reverse engineering of a varnish can be linked to different industrial objectives, such as:
Industrial objectives
Compare the composition of your varnish with a competing product
Analyze and determine the composition of an unknown varnish
Analyze and identify a contaminant or impurity present in the varnish
Check the composition of a varnish against an SDS

Our technical capabilities for varnish de-formulation
How to carry out varnish de-formulation
The success of a de-formulation lies in a thorough understanding of the intended application and the implementation of rigorous analytical methods. This makes it possible to characterize the chemical composition of the organic and mineral fractions.
De-formulation involves several key steps:
