Creative Materials 126-37-F

126-37-F is an anisotropically conductive transferable low CTE adhesive film. This product features excellent adhesion to Kapton, Mylar, glass and a variety of other substrates. 126-37 is designed to exhibit minimal flow during bonding. This product provides superior electrical conductivity when bonding circuit materials to metal back planes and heat sinks. This product has excellent adhesion to aluminum, ceramic, and a variety of other substrates. This system features excellent thermal stability and flexibility in the B-Staged form. Unlike conventional conductive materials, this product is very resistant to flexing and creasing. The product can be re-bonded many times by simply adding heat and slight pressure

    Procedure for Applying

    1. As with all adhesive bonds, surface preparation is a vital part of the process. Carefully clean both surfaces to be bonded with MEK if possible. If MEK is not compatible with the surfaces to be bonded, another suitable solvent may be substituted.
    2. Allow cleaned surfaces to dry for approximately 2-3 minutes.
    3. Locate the adhesive onto the preheated substrate(s). Smooth out any trapped air by hand, with a roller or any other smoothing device. Some pressure is advisable to ensure intimate contact between the adhesive and substrate
    4. Place the two surfaces together and cure using the guidelines above and enough pressure to hold the surfaces tightly together. Lower temperatures may be used but the cure times will be longer.
    5. Allow to cool to room temperature under the same pressure.
    6. Remove pressure. Part is ready for use.
