Please note that this product is only available with a minimum purchase of 300 litres; for smaller quantities we recommend Sherwin-Williams Acrolon 1850 as a good alternative.

Sherwin-Williams Acrolon C750V2 (formerly known as Leighs C750V2) is an isocyanate free, two-pack finish coat for exterior exposed surfaces where retention of gloss is required, and the use of isocyanate products is precluded or undesirable. Sherwin-Williams Acrolon C750V2 is normally used in conjunction with epoxy primers and undercoats and is Highways Agency and Network Rail approved.

Endorsements

Recommended Primers

Compatible with a wide range of Macropoxy, Dura-plate, Zinc Clad Epoxy Primers and Buildcoats. Acrolon C750V2 must be applied over epoxy materials within 4 days at 23°C to ensure satisfactory intercoat adhesion.

Application Conditions & Overcoating

This material should preferably be applied at temperatures in excess of 10ºC. In conditions of high relative humidity, ie 80-85% good ventilation conditions are essential. Substrate temperature shall be at least 3ºC above the dew point and always above 0°C. At application temperatures below 10°C, drying and curing times will be signifi cantly extended, and spraying characteristics may be impaired. Application at ambient air temperatures below 5°C is not recommended.
Steelwork coated with Acrolon C750V2 Special Finish should be protected from weather for 48-72 hours after application, depending on conditions. Consult our Technical Team if in doubt.

Additional Notes

Drying times, curing times and pot life should be considered as a guide only. The curing reaction of the material commences immediately the two components are mixed, and since the reaction is dependent on temperature, the curing time and pot life will be approximately halved by a 10°C increase in temperature and doubled by a 10°C decrease in temperature.

Tropical Use

Acrolon C750V2 at the time of mixing should not exceed a temperature of 35°C.  Use of this product outside its pot life may result in inferior adhesion properties even if the material appears fit for application. Thinning the mixed product will not alleviate this problem.

It is not advisable to apply this coating when the air and substrate temperatures exceed 45°C. These conditions can introduce paint film formation defects, such as dry spray, bubbling and pinholing etc. Numerical values quoted for physical data may vary slightly from batch to batch.
