Abstract
This disclosure relates to fugitive color systems and storage-stable fugitive colored liquid long-term fire retardant compositions comprising a fugitive color system. The fugitive color system comprises a fugitive color pigment. In particular, disclosed herein is the identification of fugitive color pigments exhibiting hydrophilic or diminished hydrophobic tendencies. And, in certain aspects, the fugitive color pigment is fluorescent.
Claims16
A liquid fire-retardant concentrate, the concentrate comprising a liquid fire-retardant component and an insoluble phase comprising a fugitive color system, the fugitive color system comprising a fugitive pigment and a water insoluble opaque material, wherein:
- the fugitive pigment is formaldehyde-free and comprises a fluorescent dye encapsulated within a polymeric material and is characterized by a surface free energy of at least about 45 and a polar component value of at least about 20;
- and
- the liquid fire-retardant concentrate exhibits a substantially constant storage stability for at least 7 days.
