Nanotechnology based nano zinc modified water thinnable nano hygienic emulsion primer is of finest quality and is durable, water repellent, UV resistant, fungus/ algae/ bacteria resistant, thermally insulating, elastomeric, and hence can be used as primer for a wide variety of both interior and exterior surface surfaces. Outstanding adhesion due to very high surface area of nano-materials by virtue of which it gets embedded in the surface (not a film like), high resistance to weathering (UV, Fungus, water etc.) and blistering, low VOC, high coverage area with desirable ease of application characterize this paint. Additional features include elastomeric (stretchable paint that cover cracks), quick drying, thermal and sound insulation properties. This paint produces an all season and breathable type finish. It also provides robust performance due to inorganic structurally defect-free nano-particles, incorporated in the paint matrix.
