Deformation of a coating in the laboratory

Your need : to know the chemical composition of a varnish by deformation

First of all, before talking about the deformation of a varnish, what is a varnish? A varnish is a more or less viscous liquid composition used to protect, dye or improve the surface of an industrial product. It is composed of a natural or synthetic resin in solution or dispersion in a vegetable or mineral essence.

Moreover, the varnish has several characteristics such as transparency, brightness and resistance. These characteristics vary according to the resin initially used.

In what context do you need to deform a coating?

Varnishes are made of complex mixtures. The deformation of varnishes consists in determining, by various chemical analyses ;

  • the nature of the components of this mixture
  • the quantities of materials present in the formulation of the varnish

The deformation of a varnish can be related to various industrial objectives, such as  

Industrial objectives

  • Compare the composition of your varnish to a competing product

  • Analyze and determine the composition of an unknown varnish

  • Analyze and identify a pollution or an impurity present in the varnish

  • Checking the composition of a coating against an SDS

FILAB: a laboratory dedicated to the deformation of coatings

The success of a deformation lies in a good knowledge of the targeted application and the implementation of rigorous analysis methods. Thus, it allows to characterize the chemical composition of the organic and mineral fractions.

This approach implies a set of diversified and sometimes very advanced techniques such as
