SZIP MasterSeal Waterproof zipperApplications:Waterproof clothing Fabric and Neoprene dry suits Tents, flexible covers Protective clothing for leisure, safety and industrial applications (gas and chemical protection) Flexible containers for electronic instruments and documents, and for machinery and apparatus for storage and transport Bags and backpacks for daily use and outdoor activities such as cycling, biking, sailing, hiking, climbing ...and various others The technical principle The SZIP MasterSeal is made from high-strength fabric coated with thermoplastic polyurethane. The extra strong plastic teeth are fixed on the top and bottom of the zipper tape. The zipper’s coupling elements keep the sealing edges tightly sealed together when the zipper is closed. The zipper tape can be both welded and glued.The SZIP MasterSeal slider is made from a metal compound which is non skin irritating and salt water resistant. The slider movement is contact free and does not wear on the zipper tape or the sealing edge.Tightness The SZIP MasterSeal is easy to operate, and pressure tested to 500 mbar.Dirt or Sand The SZIP MasterSeal is highly resistant to damage caused by dirt or sand. However if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function if they get caught between the chain profiles. If the SZIP MasterSealclosure is used to protect life or sensitive material, the sealing function and cleanliness of the chain area should be thoroughly checked prior to every usage. Stability The SZIP MasterSeal’s performance in terms of strength and durability is very good. However, sharp bending or twisting should be avoided. When closed, the SZIP MasterSeal has a cross-breaking strength of minimum 125 N/cm. Reinforcement For SZIP MasterSeal zippers, closed both ends and open top, we have a reinforcement for the bottom stop available. We recommend this feature for heavy duty bag applications and for main entry zippers for diving survival and water surface dry suits. The reinforcement strap holds the zipper stringers before they get bent or broken over the edge of the slider in the complete open position. Operating Force Opening and closing the SZIP MasterSeal requires moderate pulling force on the slider. Please allow a slightly higher pulling force to undock the both ends closed version. Some lubrication can help to reduce the pulling force on the docking end. The chain is maintenance free.
