Castrol Rustilo™ Aqua 639 (previously called Aquasafe™ 639) is a water-based, wax emulsion with outstanding adhesion and durability on various substrates. It dries in about 15 minutes to a satiny film, without losing its wax characteristics or lubricity. It can be used over lightly oiled surfaces and will dry to a tack-free surface.

Rustilo Aqua 639 provides a temporary protective coating to help preventing corrosion during storage and shipment of parts. It is recommended for metal surfaces, i.e. aluminum, steel, stainless steel, copper, and galvanized and plated metals, where a waxy coating can be employed to give effective exterior or interior rust protection.

Application Procedure
Application Procedure |
N/A
Rustilo Aqua 639 can be used to coat lightly oiled metal surfaces and will dry to a tack-free surface. Test a sample part to determine adhesion and film-forming properties when applying over lightly oiled or uncleaned surfaces. Since there are various types of oils, we recommend such a pretest for compatibility. Drying time depends upon temperature, humidity and air flow. At 75°F (24°C) and 45% relative humidity, Rustilo Aqua 639 dries to the touch in about 15 minutes when applied at full strength. Forced warm air and/or dilution will decrease the drying time |
Recommended Concentrations

N/A Working dilutions of Rustilo Aqua 639 should be determined by the end user. Rustilo Aqua 639 may be diluted with water, which will result in thinner films and reduced durability. Rustilo Aqua 639 water emulsion protective coating can be diluted with tap water. However, if local water is very hard, dilute Rustilo Aqua 639 with deionized water |
