Kappler Chemtape Chemical Resistant Tape (24 Rolls)

Duct tape is made to reduce air leakage in HVAC systems, while ChemTape is specifically engineered to block hazardous particles and liquids from entering the interfaces of protective garments.

• Will ChemTape provide a liquid-tight seal?
  ChemTape can create a liquid-tight seal when applied correctly. Proper application involves ensuring the tape is free of wrinkles and folds, as these can compromise performance. ChemTape uses a pressure-sensitive adhesive, and applying high pressure ensures optimal sealing. While it offers protection from chemical splashes, ChemTape should not be immersed in liquids.
• Will using ChemTape make suits gas-tight?
  No, ChemTape is not intended to provide gas-tight protection. For scenarios requiring gas-tight protection, alternative garment designs should be used.
• How should ChemTape be applied, and where should it be used on protective suits?
  ChemTape is designed to enhance liquid resistance at interfaces and closures on protective garments. It can be used on glove/sleeve interfaces, boot/boot flap areas, zippers, storm flaps, and around respirator facepieces. To apply:
  • Unwind a sufficient length of tape, then cut or tear it cleanly.
  • Apply it in a single continuous length whenever possible.
  • Press firmly by hand to ensure a strong bond.
    Multiple layers or wraps may be necessary for increased coverage in specific scenarios.
• Is ChemTape reusable?
  No, ChemTape is a single-use, disposable product.
• Does removing ChemTape affect the chemical resistance of suit materials?
  ChemTape features a strong adhesive system, which may affect some lightweight suit fabrics like Provent upon removal. Factors like temperature, exposure conditions, and time of application can impact the release characteristics. Users should inspect garments for degradation, delamination, or tearing after tape removal.
• Will additional chemicals be tested for permeation or penetration on ChemTape?
  Yes, Kappler can arrange testing for additional chemicals upon request, with a commitment to purchase if desired results are met.
• Can chemicals degrade ChemTape adhesive?
  ChemTape uses a natural rubber-based adhesive system, which can be affected by certain chemicals. Proper application, minimizing wrinkles and gaps, reduces the adhesive’s exposure to chemicals, enhancing its durability.
• Is ChemTape available in other sizes or colors?
  No, ChemTape is only available in ~2-inch x 60-yard rolls (48mm x 50m), shrink-wrapped individually. It is yellow with a black logo.
• How is ChemTape different from standard duct tape?
  Standard duct tape is designed for HVAC applications to reduce air leakage. In contrast, ChemTape is a high-chemical-barrier tape developed for use with chemical protective clothing, offering superior protection against hazardous particles and liquids. It utilizes the same technology found in Zytron protective fabrics.
• Will ChemTape removal affect the chemical resistance of gloves or damage them?
  Most chemically resistant gloves (e.g., PVC, Butyl, Viton, Neoprene) are unaffected by ChemTape’s adhesive. However, film-based gloves like 4H and SilverShield may experience some impact. Inspect gloves for signs of degradation and replace if necessary.
• Can ChemTape enhance seam holdout in protective clothing?
  Yes, ChemTape can be applied to serged or bound seams to improve holdout. Performance depends on careful application to ensure a proper seal.
• What is the temperature service range of ChemTape?
  ChemTape has a maximum recommended storage temperature of 120ºF (49ºC). Testing has shown that storage for one month at this temperature is equivalent to about one year of storage under standard conditions (73ºF or 23ºC).
• What are the temperature parameters for using ChemTape when interfacing gloves/suits for handling hot chemicals?
  Using ChemTape in conjunction with hot chemicals requires careful consideration due to potential risks. Kappler does not provide specific claims about the chemical resistance of ChemTape or its adhesive at elevated temperatures. Key considerations include:

  • Identifying the chemicals involved and their expected exposure duration.
  • Recognizing that the service temperature range is based on the softening point of the films rather than the adhesive’s operating temperature.

  The adhesive system is a natural rubber-based pressure-sensitive adhesive, similar to those used in most duct tapes, and its performance at high temperatures depends on the specific scenario. Users should contact Kappler for further guidance, including referrals to labs for testing exposure conditions and evaluating expected performance.
