Capstone™ 4-I - Dupont - #1

Text version of the page

DuPont™ Capstone™ 4-I is a versatile fluorinated iodide useful in preparing repellent and surfactant products. It is based on four fluorinated carbon molecules that cannot break down to PFOA in the environment. Capstone™ 4-I is part of a large family of fluorinated specialty monomers offered by DuPont.

Specifications Property Limit, wt% Perfluorobutyliodide 90 min Perfluoroethyliodide 2.0 max Perfluorohexyliodide 1.0 max Perfluorohexane 8.5 max Perfluorooctane 1.0 max Uses Capstone™ 4-I is a short-chain perfluorinated monomer useful in producing repellents, lubricants and surfactants. The perfluoroalkyl group of Capstone™ 4-I can provide formulations with lower surface energy, improved chemical stability and surface lubricity, and enhanced molecular orientation. In addition, Capstone™ 4-I can be oxidized to the acid fluoride and converted to carboxylic acid derivatives through hydrolysis. It can add across olefins or initiate telomerization reactions.
