PRO-SET TLG-625-R Low Density Epoxy Tooling Putty Resin 4.5 Gallon

PRO-SET® TLG-625-R Low Density Epoxy Tooling Putty Resin Only

TLG-625-R is the resin component only of PRO-SET’s low-density epoxy tooling putty system. When combined with the matching TLG-625-H Tooling Hardener (required, sold separately), it produces a lightweight, easily sandable putty designed for surfacing molds and plugs and for filling/fairing composite structures.

Why Builders Choose TLG-625

• Fast workflow: Blends quickly, spreads smoothly, shrinks minimally, and is sandable in about 8 hours.
• High build without slump: Apply in single passes up to 1/2" (12 mm) with excellent feather-edge characteristics.
• Low dust sanding: Filler blend minimizes airborne dust while finishing.
• Shear-thinning rheology: Easy mixing and smooth spreading; stays where you put it.

Typical Uses

• Surfacing and detailing of molds and plugs
• Filling and fairing of composite structures in manufacturing and repair
• General gap-filling and contouring where a lightweight, sandable epoxy putty is preferred

System & Coverage

Use TLG-625-R Resin withPRO-SET TLG-625-H Tooling Hardener (sold separately). At room temperature, the system provides approximately 90 minutes of working time. One mixed gallon of tooling putty covers about 6.4 ft² at 1/4" thickness (coverage varies with substrate and technique).

Mixing & Application

• Follow the mix ratio and instructions on the PRO-SET TDS for the TLG-625 system.
• Measure accurately and blend thoroughly until uniform; scrape sides and bottom of the mixing container.
• Apply to clean, abraded, and dust-free substrates. Build as needed up to 1/2" (12 mm) in a single application.
• Allow to cure; sand and finish as required. Post-cure per TDS if elevated properties are desired.

Storage & Handling

• Resin only: This listing includes TLG-625-R resin. OrderTLG-625-H Tooling Hardener separately.
