Description

  The present invention relates to a surface treatment agent, particularly a water / oil repellent and an antifouling agent.

Conventionally, a fluorine-containing water and oil repellent containing a fluorine compound is known. This water / oil repellent exhibits good water / oil repellency when treated on a substrate such as a textile product.
From recent research results [EPA report "PRELIMINARY RISK ASSESSMENT OF THE DEVELOPMENTAL TOXICITY ASSOCIATED WITH EXPOSURE TO PERFLUOROOCTANOIC ACID AND ITS SALTS" (http://www.epa.gov/opptintr/pfoa/pfoara.pdf)] Concerns about the environmental impact of PFOA (perfluorooctanoic acid), a type of fluoroalkyl compound, have become apparent, and on April 14, 2003, EPA (US Environmental Protection Agency) will strengthen scientific research on PFOA Announced.

We also announced that telomers are used in many products such as foam, water- and oil-repellent and antifouling foams, care products, cleaning products, carpets, textiles, paper and leather. Yes. There is concern about the accumulation of fluorine-containing compounds in the environment.

Must be given. High energy is required for heat treatment at high temperature.
Furthermore, the fluoropolymer is expensive.

Therefore, it may be desired not to use a fluoropolymer or to reduce the amount of the fluoropolymer.
