KC77 Fire Retardant Tape is a flexible tape with high expansion rate, fire prevention and heat insulation. It is mainly used for fireproof plugging of cracks around single or cluster cables, wind pipe, plastic pipe penetrations and metal penetrations. It has good water resistance, acid and alkali resistance, moisture and heat resistance, and freeze-thaw resistance. It is free of volatile organic matter, asbestos, fiber dust and other harmful substances, safety and environmental protection without pollution. It uses the combination of chemical expansion and physical expansion technology, rapid expansion in case of fire, with the rise of temperature formed with the strength of the carbonization layer tightly filled through the holes of the gap, block the spread of flame and smoke, with more than 3 hours of fire aging. At the same time, the product in the harsh, dirty and other outdoor environment, still can maintain the normal fire function.

Direction for Use
1. Clean the hole, the debris around the perforation, dust, keep the sealing position dry and clean
2. Measure the size of the plugging position, calculate the appropriate length, and cut by hand。
3. The KC77-E fire retardant tape is tightly wound around the through-piece, which can be fixed with straps and pipe clips, and the winding is completed
