EA 1C™ is a general purpose adhesive and sealant
that bonds, seals, and repairs a wide variety of materials
including metals, most plastics, and wood.

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Directions For Use:


  1. When mixing by hand, combine Part A (Resin) and
    Part B (Hardener) in the correct ratio and mix thoroughly
    until the color and consistency are uniform. EPOXIPATCH®
    Tube Kits have been designed so that
    squeezing EQUAL LENGTH BEADS of Part A & Part B
    will give the proper ratio.
  2. Mixing the adhesive just prior to use is recommended.
    The temperature of the separate components prior to
    mixing is not critical, but should be close to room
    temperature: ºC (ºF).
  3. Heat buildup during and after mixing is normal. To
    reduce the likelihood of exothermic reaction or
    excessive heat buildup, mix less than 1,000 grams at a
    time. Mixing smaller amounts will minimize heat buildup


  1. Bonding surfaces should be clean, dry, and free of
  2. Once the adhesive is applied, the bonded parts should
    be held in contact until the part has developed handling
    strength (3 to 4 hours @ 25 °C) note: this can vary with
    different bond configurations. It is not necessary to
    clamp the parts unless movement during cure is likely.


  1. Complete cure is obtained after 72 hours @ 25 °C.
    EA 1C™ can also be fully cured with heat
    such as; 2 hours at a maximum temperature of 60 °C.
  2. After 24 hours, approximately 90% of full cure properties
    are attained at room temperature.
  3. This product can also be cured for 1 hour @ 82°C or 20
    to 30 minutes @ 121°C.
  4. Heat cures can be modified to achieve a desired degree
    of cure from handling strength to full cure

Clean up

  1. It is important to clean up excess adhesive from the work
    area and application equipment before it hardens.
  2. Denatured alcohol and many common industrial
    solvents are suitable for removing uncured adhesive
