Description
Surebonder 925R10 is a clear, 1 ⁄ 2″ diameter × 10″ high-strength acrylic hot-melt stick engineered to grip hard-to-bond surfaces such as aluminum, steel, glass, vinyl, concrete, and engineered woods. Originally developed for securing carpet tack strips to concrete, it has become a shop staple for:
-
Rapid fixture of reverse channel letters before applying LORD® Signlok™ 406 or other two-part structural adhesives (no more burn-through or grinding).
-
Cabinetry templating and countertop build-ups.
-
Installing carpet tack strips on masonry and sub-floors.
-
General assembly where a fast, tough bond is needed on plastic, metal, ceramic, or wood.
The 60–80 second open time lets installers adjust parts while still reaching handling strength in about a minute—keeping production lines moving.
Key Features & Benefits
-
High green strength on metals, plastics, concrete & wood.
-
60 s open time offers working latitude without slowing throughput.
-
Medium viscosity for smooth beads and gap-fill to ¹⁄₁₆″.
-
165 °F softening point withstands warm-weather transport and storage.
-
Complies with FDA 21 CFR 175.105 for indirect food packaging.
-
Clear formula minimizes show-through on back-lit or stainless letters.
-
Formerly sold as HM612 Hot-Melt—same trusted formulation, new part number.
