Surface-modifying coating compositions

摘要: Coating compositions suitable for application to optical surfaces reduce surface misting and light reflection without creating haze comprise: (a) an inorganic particulate component selected from colloidal silica particles, alumina or a mixture thereof wherein the particles have small particle size represented by average in range 7 50 nm comprise 0.5 2.5% weight/volume of total composition; (b) another also large 75 150 0.2 1.0% (c) 0.1 polymeric binder; (d) volatile liquid medium. The coating provide especially beneficial properties when applied thermoplastic films sheets, -such as polyethylene terephthalate films. Such are coverings claddings horticultural growing houses, cold frames cloches.
