1 WEATHERMAX HBR MIO. High Build Recoatable Polyurethane PC 406. FEATURES EXCELLENT HIGH BUILD BRUSH & ROLLER APPLICATION. SUPERIOR GLOSS & COLOUR RETENTION. CAN BE APPLIED UP TO 125 MICRONS DFT IN A SINGLE COAT VIA SPRAY APPLICATION. GOOD ABRASION RESISTANCE. ACCELERATOR AVAILABLE FOR USE IN COOLER CONDITIONS. AVAILABLE IN TWO MICACEOUS IRON OXIDE FINISHES.. USES WEATHERMAX HBR MIO has been locally developed for high build roller or brush application. It is a high build recoatable polyurethane coating designed to be used over a wide range of suitably primed substrates such as mild steel, galvanised steel, concrete and aluminium.
2 The micaceous iron oxide pigment particles interlock in the film to form a barrier against moisture ingress. WEATHERMAX HBR MIO is a high performance coating that exhibits excellent gloss and colour retention during extended service periods in severe industrial and marine environments and in extreme UV exposure SPECIFICATIONS AS/NZS Tested in accordance with Appendix C & D for use as a concrete anti-carbonation coating system when used with Durebild STE. RESISTANCE GUIDE. WEATHERABILITY Excellent gloss and colour retention on SOLVENTS Resists splash and spillage of most exterior exposure hydrocarbon solvents, refined petroleum products and most common alcohols HEAT RESISTANCE Up to 120 C dry heat WATER Excellent resistance to fresh and salt water but not suitable for immersion SALTS Unaffected by splash and spillage of neutral ALKALIS Good resistance to splash and spillage and alkaline salt solutions of most common alkalis (except MIO.)
3 Mid Grey). ACIDS Excellent resistance to splash and spillage of ABRASION Good when fully cured most acids (except MIO Mid Grey). TYPICAL PROPERTIES AND APPLICATION DATA (STANDARD HARDENER).
