| 摘要 |
The present invention obtains from the discovery that combining traditional UV pigments, organic chemicals, or both, combined with NA, creates a broad spectrum UV absorbing additive that is much more efficient than using any of the ingredients by themselves. Methods for producing NA-coated particles as a UV protection additive to paints, fiberglass, plastic, polymers, siloxanes/silicates/reactive silanols, sealants or other film forming coatings or penetrating fluids and solid articles are contemplated in this invention as well as the coatings, sealants and other protectants and the coated and/or finished articles themselves.
