Deformulation of varnish in the laboratory
Your need : to know the chemical composition of a varnish by deformulation
First of all, before talking about the deformulation 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 deformulation of varnishes consists in determining, by various chemical analysis ;
- the nature of the components of this mixture
- the quantities of materials present in the formulation of the varnish
The deformulation 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 deformulation of coatings
The success of a deformulation 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
