AS/NZS 3750.3:2008

Specifies requirements for single- and multi-component primers and finishing coats for the protection of steel against atmospheric corrosion at elevated temperatures.

This Standard sets out requirements for single- and multi-component primers and finishing coats for the protection of steel against atmospheric corrosion at elevated temperatures. Paints specified in this Standard include those described as Paint References C27, C31 and C35 in AS/NZS 2312.Temperature resistance, colour range, gloss level and drying times vary significantly according to type. These products can normally be applied by brush, roller or spray although airless spray application is not suitable for some types. Abrasive blast cleaning is the preferred method of surface preparation, however hand or power tool cleaning may be acceptable for some products that are exposed at lower temperatures. Some products require the application of heat to achieve their full resistance properties.NOTES: 1 These paints may be used for the appropriate systems detailed in AS/NZS 2312.2 Appendix A provides recommendations on information which should be provided by the purchaser at the time of enquiry or order.3 Additional information on the use and application of heat resisting paints is contained in Appendix B.4 Some products covered by this Standard may be particularly prone to discolouration or damage due to atmospheric contamination where there are acid or alkaline conditions, and the manufacturer’s advice should be sought.
