H.B. Fuller TS820

H.B. Fuller TS820 is a two-part, 1:1 mix ratio, toughened adhesive with less odor than most acrylic adhesives. TS820 Adhesive has excellent shear and peel strengths along with good impact resistance and durability. TS820 Adhesive quickly bonds most metals and ceramics with minimal surface preparation.

Features & Benefits

Features & Benefits
  • Low odor Acrylic Adhesive
  • Strong and durable adhesion
  • Minimal surface preparation
  • 1:1 mix ratio
  • Excellent shear and peel strength
  • High bond strength to stainless steel and galvanized steel

Applications & Uses

General Instructions
  • For best performance bond surfaces should be clean and free of grease. Extensive surface preparation is not required.
  • Mixing part A and part B in the correct ratio and mix thoroughly. Once mixed, it should achieve a uniform color. It is recommended that either meter mix equipment or cartridges with static mix nozzles be used to properly ratio and dispense the adhesive.
  • To assure maximum bond strength, surfaces must be mated within the adhesive’s open time. Use enough material to completely fill the joint when parts are clamped.
  • Do not return unused material to container as it would result in contamination and/or premature hardening of contents

Handling and Clean-Up

Clean up is best before the adhesive has cured. Cleaners containing NMP (N-methyl pyrolidone) or Citrus terpene provide the best results. On cured adhesive repeat use may be required.


TS820 Low odor Structural Adhesive should be stored in unopened containers in a cool, dry area at a temperature between 8°C and 25°C.
