Adhesive FAQ

  • What do you do if the CN adhesive does not harden or a strain gauge does not adhere well?

    There are two major reasons for not hardening. If the temperature or humidity is low, time may be required for hardening. Use an CN accelerator (sold separately) or apply pressure for a longer period and it will harden or adhere. However, if the temperature is 5℃ or less, the product may not harden.
    In addition, if the surface to be adhered to is acidic, it will hinder hardening. Here, the surface must first be treated and neutralized.

  • How much of solution B of P-2 adhesive should I put in?

    The standard is 2% to 6%. There are three reference lines on the adhesive adjustment pan, and it is approximately 10 g when solution A reaches the lowermost line.
    35 drops of solution B are about 1 g, so 7 drops are 2% and hardening occurs at 20℃ in about 1 hour and a half.
    Refer to the illustrations in the supplied instruction manual.

  • Do you sell individual CN adhesives?

    No. Please purchase in units of one bag (five pieces).

  • How many strain gauges can be adhered with one bag of CN adhesive?

    Depending on how it is used, approximately 250 to 350 of FLA-6 strain gauges.
