SylWrap CR Corrosion Protection Wrap

How to protect against corrosion using SylWrap CR Corrosion Protection Wrap

SylWrap CR is easy to use. Dipping the bandage into water activates the resin. When applying underwater, the resin activates as soon as it comes into contact with water. The user then wraps SylWrap CR around the pipework or structure.

To achieve the recommended coverage of five layers, wrap the first layer so that the overlap with each wrap around is approximately 5mm.

The subsequent two wraps are applied with a 50 percent overlap to provide a total of five layers. As an alternative, apply all three layers of SylWrap CR with a 50 percent overlap to achieve six layers in total.

Further water smooths the bandage down as the application continues, ensuring SylWrap CR conforms tightly to the pipe.

SylWrap CR has a work time of 2-5 minutes. It achieves a functional cure in 30-45 minutes and a full cure with maximum properties in 24 hours.

Sylmasta make all their own composite pipe repair and protection bandages at their world-leading production facility in the United Kingdom.

This guarantees fresh product, a reliable supply chain and reduced lead times. It also means Sylmasta can produce customised wraps based on client needs.

Sylmasta have previously manufactured different coloured bandages to better disguise repairs and composite wraps with slower-setting resin for use in hot climates. If you require specialist bandages for a specific application, please contact Sylmasta.
