Nitozinc Primer page 1 of 3 Two component epoxy zincrich primer Uses Nitozinc Primer is recommended for priming exposed steel reinforcement for use with Fosroc concrete repair mortars. The product actively resists corrosion within the confi nes of the repair location and avoids the generation of incipient anodes in immediately adjacent locations. Nitozinc Primer is compatible with all Renderoc mortars and fl uid micro concretes. Advantages ??? Anti corrosive - Active 'Zinc-rich' system combats corrosion by electro chemical means. ??? Two component product - Easy to mix and use. ??? Timesaving - Touch dry after 30 to 45 mins. ??? Excellent adhesion - Exhibits excellent bond strength in cementitious repairs. Description Nitozinc Primer is supplied as a two component system based on metallic zinc and epoxy resin which on mixing gives a grey coloured liquid. Technical support Fosroc off ers a comprehensive range of high performance, high quality concrete repair and construction products. In addition, Fosroc off ers technical support service to speci- fi ers, end-users and contractors, as well as on-site technical assistance in locations all over the country. Design Criteria One or two coats of Nitozinc Primer are generally required, dependent largely on the nature and profi le of the substrate. Nitozinc Primer is recoatable generally between 30 minutes and one hour after the application of fi rst coat. Application of top coat may also proceed at this time. At elevated temperatures, the recoatable and overlay times will be reduced. The minimum application temperature for Nitozinc Primer is 100 C. The local Fosroc offi ce may be consulted for further information. Properties Specifi c gravity 1.75 Wet fi lm thickness/coat 100 microns Dry fi lm thickness/coat 40 microns Total zinc content in dry fi lm >84% by weight ??? Adhesive bond strength > 1.5 N/mm2 with steel (ASTM D4541) Pot life : 30 minutes @ 30oC Application thickness 100 microns (wet) per coat Drying times @ 20 0C @ 35 0C Touch dry 45 mins 15 mins Fully dry/Recoatable 45 minutes to 1 hour. Surface drying time @270C 20 to 40 mins. Note : At temperatures below 20 0C, the drying times will be slower. Conversely, at temperatures above 350C, the drying times will be faster. Specifi cation clauses Steel reinforcement primer Performance specifi cation The steel reinforcement primer shall be an epoxy, two component, zinc rich liquid packed and supplied ready to use. An unbroken 40 microns DFT coating shall be capable of providing???active??? galvanic protection and avoiding the generation of incipient anodes in the immediately adjacent locations. It shall be of suitable viscosity to enable the coating to penetrate into imperfections and pits within the surface of the structural steel. The formulation of the primer shall be such that drying occurs to allow the application of the repair mortar after 45 minutes at 350C or after one hour at 200C. It shall be fully compatible with the reinstatement methods adopted. Supplier specifi cation The steel reinforcement primer shall be Nitozinc Primer, manufactured by Fosroc and used in accordance with the manufacturer???s datasheet. Nitozinc Primer is fully compatible with Fosroc???s reinstatement techniques.
