FST6525 Self-curing waterproof protective wrap material (waterproof sticker) is an insulating waterproof packaging material, the main feature is excellent insulation and waterproof performance, can be used for insulation protection of 35kV and below cables, optical cables, overhead lines and bare metal wires At the same time, it can also be used in the waterproof protection of equipment such as outdoor base station connectors, shaped antennas, splitters, couplers, tower defense, GPS integrated cabinets and other equipment.

During the construction of this product, you only need to pinch the location to be treated with a waterproof sticker, and then the material itself will gradually solidify after contact with the air to form an insulating waterproof layer. The operation is simple, suitable for quick repair work, without heating or special tools. On-site operation can cut and plasticize the waterproof sticker according to the actual situation.
