ET-HP™ ANCHORING ADHESIVE

AUTHORIZED SIMPSON STRONG-TIE DISTRIBUTOR

ET-HP™ is a two-component, high solids, epoxy-based system for use as a high-strength, non-shrink anchor grouting material. Resin and hardener are dispensed and mixed simultaneously through the mixing nozzle. ET-HP meets the ASTM C-881 specifications for Type I, II, IV and V, Grade 3, Classes B and C, except gel time.

APPLICATIONS:
  • Threaded rod anchoring
  • Rebar doweling
  • Bonding hardened concrete to hardened concrete
  • Pick-proof sealant around doors, windows and fixtures
  • Paste-over for crack injection

  1. Cartridge estimation guides are available, or see Simpson Adhesive Cartridge Estimator to the right.
  2. Detailed information on dispensing tools, mixing nozzles and other adhesive accessories is available under the “Accessories” tab.
  3. Use only appropriate Simpson Strong-Tie mixing nozzle in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair epoxy performance.

  • CURE SCHEDULE:

    For water-saturated concrete, the cure times are doubled.

    IN-SERVICE TEMPERATURE SENSITIVITY

    1. Refer to temperature-sensitivity chart for allowable bond strength reduction for temperature. See Supplemental Topics for Adhesive Anchors.
    2. Percent allowable load may be linearly interpolated for intermediate base material temperatures.
    3. °C = (°F-32) / 1.8
    CHEMICAL RESISTANCE:

    Very good to excellent against distilled water, inorganic acids and alkalis. Fair to good against organic acids and alkalis, and many organic solvents. Poor against ketones. For more detailed information, see Technical Bulletin T-SAS-CHEMRES.

    STORAGE:

    For best results, store between 45–90° F. Unopened cartridge has shelf life of 24 months from date of manufacture. To store partially used cartridges, leave hardened nozzle in place. To re-use, attach new nozzle.

    COLOR:

    Resin – white, hardener – black. When properly mixed, ETHP adhesive will be a uniform medium gray color.

    CLEAN UP:

    Uncured material — Wipe up with cotton cloths. If desired scrub area with abrasive, waterbased cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material: Chip or grind off surface.

  • Surfaces to receive epoxy must be clean. For installations in or through standing water, see Supplemental Topics for Adhesive Anchors for details. The base material temperature must be 40°F or above at the time of installation. For best results, material should be 70°F – 80°F at the time of application. Cartridges should not be immersed in water to facilitate warming. To warm cold material, the cartridges should be stored in a warm, uniformly heated area or storage container for a sufficient time to allow epoxy to warm completely. Mixed material in nozzle can harden in 5–7 minutes at a temperature of 40°F or above.

    When the concrete temperature is at or below freezing, ensure any holes drilled in advance are free of frost or ice.
