COLOR-STABILIZED IODOPROPYNYL BUTYLCARBAMATE |
摘要 |
Microparticles containing an ultraviolet light absorbing polymer and 3-iodo-2-propynyl butylcarbamate (“IPBC”) resist discoloration by sunlight and other ultraviolet light sources. Methods for preparing the microparticles produce polymer-shielded, formaldehyde-free IPBC formulations which resist discoloration and leaching, and are especially useful in water-based applications. The microparticles include a polymer or a poly(vinyl formal) homopolymer that absorbs light over a range of ultraviolet wavelengths associated with IPBC discoloration. The microparticles may be utilized in paints, stains, stuccoes, adhesives, and plastics, for example. |

1. Microparticles for stabilizing 3-iodo-2-propynyl butylcarbamate against discoloration, which comprise:
a poly(vinyl formal) homopolymer that absorbs light over a range of ultraviolet wavelengths associated with 3-iodo-2-propynyl butylcarbamate discoloration by sunlight and other ultraviolet light sources; and a biocidal composition including 3-iodo-2-propynyl butylcarbamate and optionally, an additional biocidal material; which microparticles stabilize 3-iodo-2-propynyl butylcarbamate against discoloration by sunlight and other ultraviolet light sources, and have a particle size in the range of more than 20 to about 1000 microns and a surface area in the range of about 0.001 to about 0.9 m2 per gram. |
