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.

values based upon results from the most recent testing and may not reflect those
in current code reports. Where code jurisdictions apply, consult the current
reports for applicable load values.
APPLICATION
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.

TEST CRITERIA
Anchors installed with ET-HP™ adhesive have been tested in accordance with ICC-ES's Acceptance Criteria for Adhesive Anchors in Masonry Elements (AC58) and Adhesive Anchors in Concrete Elements (AC308).
In addition, anchors installed with ET-HP adhesive have been tested in
accordance with ICC-ES's Acceptance Criteria for Unreinforced Masonry Anchors
(AC60).

SUGGESTED SPECIFICATIONS
Anchoring adhesive shall be a two-component high solids epoxy based system supplied in manufacturer's standard side-by-side cartridge and dispensed through a static-mixing nozzle supplied by the manufacturer. Epoxy shall meet the minimum requirements of ASTM C-881 specification for Type I, II, IV, and V, Grade 3, Class B and C, except gel time, and must develop a minimum 13,390 psi compressive yield strength after 7 day cure. Epoxy must have a heat deflection temperature of a minimum 168°F (76°C). Adhesive shall be ET-HP™ adhesive from Simpson Strong-Tie, Pleasanton, CA. Anchors shall be installed per Simpson Strong‑Tie instructions for ET-HP™ adhesive.
SHELF LIFE
24 months from date of manufacture in unopened container.
STORAGE CONDITIONS
For best results store between 45°F - 90°F. 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.
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.
ET Cartridge Systems
- Cartridge and bulk estimation guides are available.
- Detailed information on dispensing tools, mixing nozzles and other adhesive accessories is available.
- 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.
In-Service Temperature Sensitivity
- Refer to temperature-sensitivity chart for allowable bond strength reduction for temperature. See Supplemental Topics for Adhesive Anchors.
- Percent allowable load may be linearly interpolated for intermediate base material temperatures.
- °C = (°F-32) / 1.8
