Effect of free-based light trigger content on UV curing process.

A new study examines the effects of free-based light trigger content on UV-cured blended sol-gel films.
-gel coatings are widely used as protective layers for aluminum alloys due to their barrier capacity.
the study aims to illustrate the barrier properties of sol-gel coatings based on alkyl trimethylsilane and methyl acrylic resins through their membrane

.
method is tested by modifying a light polymerization parameter, for example by changing the content of a free-based light promoter.
Pulation performance
results show that formulations containing 3 to 9 wt% free-form light triggers show the maximum conversion rate of methyl acrylates function and show an equal coating at the microscale, where organic and inorganic networks penetrate each other well.
this hybrid sol-gel microstructit corresponds to the highest glass transition temperature and the highest mechanical properties (elastic modulation, E and hardness, H) and maximum protection. This results in optimum barrier performance and therefore the highest corrosion resistance.
the study has been published in the Journal of Coating Technology and Research. 17, question 2.
