Microsun Zinc Oxide W45/30 in Water Dispersion

Microsun™ Zinc Oxide W45/30 is a water based dispersion specially formulated for incorporation into paints to produce a transparent film of finely dispersed nano Zinc Oxide. Using paints that include Microsun™ Zinc Oxide W45/30 provide an added barrier of protection from UV radiation that otherwise can result in reduced gloss retention, breakdown of coating (chalking) and subsequent damage to a coated substrate. Microsun™ Zinc Oxide W45/30 is ideal for use in outdoor or exterior paints where improved weatherability and longevity is a key benefit. Microsun™ Zinc Oxide W45/30 has known antibacterial and antifungal properties which can assist in reducing surface build up.
