Simpson Strong-Tie, the leader in engineered structural connectors and building solutions, introduces Timber-SET™ epoxy gel, the first ICC-ES evaluated epoxy adhesive for anchoring threaded rod in glulam beams and columns. Timber-SET provides reliable, concealed connections throughout a mass timber structure and can be used for steel-to-wood, column-to-column, column-to-foundation, beam-to-column and beam splice connections.
Timber-SET develops high bond strength to wood substrates and provides a stiff load-transfer medium critical for structural anchorage. Its gel viscosity supports effective encapsulation of threaded rods while minimizing voids and limits adhesive flowing out of the hole during horizontal installations.
In addition, the Timber-SET thixotropic formulation allows adhesive to flow under pressure, and its neutral gray color minimizes potential for staining exposed timber.
“Timber-SET offers good working time for installation and strong adhesion under dry wood conditions, making it well-suited for structural timber anchorage applications,” said Michael Weinert, senior product manager for Simpson Strong-Tie. “For a total glued-in rod solution, install Timber-SET with Simpson Strong-Tie threaded rods, centering and retaining caps, dispensing and cleaning tools, and Strong-Drive® structural screws.”
Timber-SET is approved for five rod diameter options: 1/2", 5/8", 3/4", 7/8" and 1". It comes in 32-ounce dual cartridges.
