Recommended Topcoats
Indefinitely self overcoatable provided the coating has been suitably cleaned. For optimum intercoat adhesion with other epoxy topcoats, overcoating should occur within 14 days. Where atmospheric exposure is required overcoat with Acrolon C137V2, Acrolon C237, Acrolon 1850 and Acrolon 7300 within 7 days at a minimum d.f.t. of 50 microns or in the case of Acrolon C750V2 overcoat within 4 days.
These overcoating times refer to achievement of optimum adhesion at 23°C and will vary with temperature.
For overcoating outside the above parameters and with alkyd systems, consult the Technical Department for advice.

Questions
 Ian Anderson on 09/09/2018 | Question: Can Sherwin-Williams M922 be applied to very high temperatures on stainless Steel |
Answer: The Sherwin-Williams Macropoxy M922 data sheet states 'Macropoxy M922 may be applied by brush onto hot surfaces up to 120°C. Multiple coats will be necessary to achieve required film build. Ensure good ventilation and adequate PPE due to rapid vapourisation of solvent from the film at high temperatures.' Preparation on stainless steel should be blasting with non-metallic abrasive to ensure an adequate blast profile. | |
