Best Uses

Sherwin Williams Macropoxy M905 is formulated for application onto suitably primed surfaces, as an undercoat for use under suitable high performance finishes, where low temperature curing is required. Recommended for rapid overcoating and faster handling times.


Compatible with a wide range of epoxy primers Epigrip M902 Winterfast Hi-Build Brushing Aluminium (preferred primer). Recommended application via airless spray, roller or brush. Recommended cleaners / thinner no5 for thinning and no9 or no13 for cleaning. For overcoating with epoxy products (including self overcoating), the maximum recommended interval is 28 days at 23°C.

Where a high degree of gloss and colour retention is required overcoat with Resistex C137V2, Resistex C237, Acrolon 1850 and Acrolon 7300 within 7 days at a minimum DFT of 50 microns or in the case of C750V2 overcoat within 4 days. These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.
