KC80 Waterproofing tape (raw rubber)

It is used for waterproofing cable joints, as well as for sealing cable connections with other devices (antennas, filters, amplifiers, base stations). Made of ethylene propylene rubber (EPR) and butyl adhesive mastic. Thanks to its chemical composition, the tape has the property of self-vulcanization, which leads to the formation of a continuous hermetic rubber coating, without separation of layers. The high degree of elasticity and stretching of the tape allows it to repeat the shape of sealed joints well. Similarly, the tape has a high degree of adhesion to copper, aluminum and cable protective sheaths. KC80 has excellent waterproofing characteristics and temperature stability at 90°C, and can withstand operating temperatures from -55°C to 130°C.

Instructions for use

Cotran KC80 Waterproofing Mastic Tape should be applied in an overlapping manner until the desired level of insulation is achieved.

Step 1. Before winding, make sure that there is no dust at the connection point. To facilitate further possible disassembly of the connection, it is recommended to apply a layer of insulating tape KC63 before sealing the joint of the waterproofing mastic tape.

Step 2. Remove the paper backing and stretch the tape 1-2 times its original length, overlap the tape, applying a mastic layer to the joint. It is not recommended to stretch the tape more than 4 times from its original length.

Step 3: Make sure there is 30mm to 50mm of waterproofing tape on both sides of the joint area.

Step 4. After applying the mastic waterproofing tape KC80, it is recommended to wind the insulating tape KC63. It is recommended to apply 3 layers of KC63 insulating tape in a 50 percent overlap without tension. Be careful not to pull the PVC tape during installation.
