  • THERMAL STABILIZATION OF IPBC BIOCIDE
    Publication number: 20140213645
    Abstract: A biocide, e.g. IPBC (3-iodo-2-propynl butylcarbamate), is stabilized against thermal degradation in matrix compositions which are processed at elevated temperatures, by blending the IPBC with a stabilizer additive, e.g. calcium stearate and/or a hindered phenol, alone or in combination therewith.
    Type: Application
    Filed: March 28, 2014
    Publication date: July 31, 2014
    Inventor: Joseph A. Bartko
  • Free-flowing composition of a biocide and a processing additive therewith for incorporation into a polymer or plastic matrix product
    Publication number: 20060229381
    Abstract: A matrix which is a polymer, plastic or polymer-wood composite includes a composition of a biocide and a processing additive therewith in the form of a free-flowing powder.
    Type: Application
