Explore allWater-based, economical protective coating for use on OCTG pipe OD in demanding outdoor conditions
Description
Vincit 645 is a highly cost effective, stable aqueous emulsion which contains advanced co-polymers and specialised corrosion inhibitors. They dry to form a transparent tough film lacquer which is resistant to mechanical damage.
The anti-corrosive coating is easy and inexpensive to apply with several options available such as an airless spray gun, paint roller or brush.
Well maintained stocks of OCTG are essential given the severe forces experienced during offshore operation and the small cost of a preservative coating is worth avoiding an expensive pipe failure. Vincit 645 is ideal for the preservation of ferrous metals and finished surfaces without affecting their appearance, including the OD surfaces of OCTG.
Vincit 645’s aqueous emulsion is low on VOCs (preventing solvent loss). It is UV resistant and is ideal for extreme temperatures and climates.
Vincit 645 is a water based emulsion that is supplied essentially ready for use. During transportation and storage there is potential for some settling to occur and therefore stirring the product prior to use is advised.
A variety of application techniques are possible including airless spraying, paint rolling and brush. our recommended application is by airless spray. if brushes and rollers are used care should be exercised to prevent coating “drag” in view of the short time required to achieve touch dry films. under extreme ambient temperature conditions (>80 degrees C surface temperature) wetting the subject with water will assist in achieving an even drying by delaying rapid emulsion break.
To check the wet film thickness during application we recommend the use of a “comb” type w.f.t. gauge in qa since this invariably measures thickness “over profile”.
The drying time of the coating varies in response to ambient temperature, humidity and ventilation. touch dryness may be achieved within fifteen minutes but full mechanical strength may not develop for several further hours. the coating should not be exposed to direct rainfall or water until coating is dry.
