Application of perfluorinated polymeric leveling agent

With lower surface tension, it is used in various self-drying coatings, baking paints and solvent-borne and solvent-free systems, including but not limited to the following applications.

● Coil coatings and can coatings
●Nitro, acid-curing, polyurethane wood coatings
●Industrial baking paints
● Light-curing coatings
● Automotive coatings

Peroxide initiators [8~6.
Peroxide is the most widely studied free radical initiator. About 90% of peroxides sold commercially are used as initiators. The general formula of peroxide is:
In the formula of RO-O-R’, R and R’can be hydrogen, alkyl, acyl, carbonate, etc. The two can be the same or different. As the structure of the R group changes, the initiator activity varies greatly. The activity order of peroxide initiators is generally: peroxydicarbonates>peroxydiacyls>peroxyesters>peroxydialkyls>hydrogen peroxide.

1. Organic Hydrogen Peroxide
The general formula of organic hydrogen peroxide is R OOH, fischer tropsch wax hs code but when R is methyl or ethyl, hydrogen peroxide will decompose explosively and cannot be used as an
initiator. Commonly used hydrogen peroxide initiator.
Main organic hydrogen peroxide initiator
The thermal decomposition reaction of organic hydrogen peroxide is shown in the following formula:
R OOH heating RO·+·OH(4-8) decomposes to generate two free radicals that can initiate monomer polymerization. Since there are active hydrogen atoms on the peroxy
bond of hydrogen peroxide, an inductive reaction occurs to make this type of initiator initiating efficiency. For example, the mixture of tert-butyl hydroperoxide and
di-tert-butyl peroxide at 1.1 can greatly reduce the decomposition half-life.
