Unsaturated polyesters and unsaturated polyester varnishes
Please present the composition of unsaturated polyester resin varnish
The main component of the varnish contains a styrene solution of unsaturated polyester resin and an accelerator. The main component of the paints also contains pigments. The hardener, on the other hand, contains peroxides.
Please describe the curing of unsaturated polyester resin varnish
The peroxides contained in the hardener initiate, after mixing with the main component of the varnish, chemical curing process by polymerization involving unsaturated polyester and styrene as a solvent. The solvent is therefore a component of the coating itself.
In what materials painters and varnishers use unsaturated polyester resins as a binder?
Painters and varnishers use unsaturated polyester resins as a binder in polyester putties, including spray putties for varnishing furniture.
