SylWrap CR Corrosion Protection Wrap
SylWrap CR Corrosion Protection Wrap is a composite repair wrap infused with corrosion inhibitors to protect pipes and structures in harsh, aggressive environments against substrate corrosion.
Applying SylWrap CR to pipes, steel structures, metal piles and concrete pillars prevents saltwater and environmental corrosion from occurring in marine environments. Application can take place underwater.
In testing, metalwork wrapped in SylWrap CR and subjected to 1,000 hours of saltwater exposure returned corrosion free when the protection bandage was removed.
SylWrap CR is also used to protect pipes and metal parts against abrasive wear in gravel and sand plants, quarries, sugar mills, gran hoppers and coal chutes.
It is effective in high-temperature situations up to 250ºC, resists pressure up to 30bar and can be applied in under 30 minutes, setting rock-hard for a permanent, impact-resistant protective layer.
No formal training is needed to use SylWrap CR. Simply follow the instructions provided and wrap your pipework or structure to increase corrosion resistance.
How to protect against corrosion using SylWrap CR Corrosion Protection Wrap
SylWrap CR is easy to use. For dry applications, dip the Wrap in water to activate the resin. For protecting marine structures, no prior preparation is needed as the Wrap will be activated as soon as it comes into contact with water.
Once wetted, the Wrap is applied to the pipe requiring protection from corrosion. In order to achieve the recommended coverage of 5 layers of SylWrap CR, the first layer should be wrapped so that the overlap with each wrap is approximately 5mm.
The subsequent two wraps can be applied with a 50% overlap to provide a total of 5 layers. As an alternative, and if necessary, apply all three layers of SylWrap CR with a 50% overlap to achieve 6 layers in total.
SylWrap CR has a work time of 2-5 minutes. A functional cure is achieved in 30 minutes and a full cure with maximum properties in 24 hours.

SylWrap CR Corrosion Protection Wrap Repair Calculator
The SylWrap Calculator determines the optimum SylWrap CR application for your pipe repair.
Enter the diameter of the pipe in millimetres, the length of the area to be repaired and the pressure resistance required.
The safety factor is a multiple to include a margin of safety. For example, if pipe pressure is 10 and you want a safety factor of two, then the calculator will formulate a repair capable of withstanding 20bar.
Once you have entered your data, the calculator will show the size of SylWrap CR, the quantity of bandages required, and the number of layers which should be wrapped.
