Semi-Permanent Release Agent for Carbon Fiber Drone Molds
A fluoropolymer-based semi-permanent mold release agent for carbon fiber and glass fiber drone frame molds, propeller blade mandrels, and body shell tooling operating under epoxy infusion, prepreg autoclave, and vacuum bagging processes.
Key Features
- ✓15–30 releases per application cycle — dramatically reduces mold prep downtime vs wax or PVA re-release
- ✓Surface energy 18–22 mJ/m² — releases even aggressive toughened epoxy systems cleanly
- ✓Process temperature range RT to 180°C — one system covers all drone composite manufacturing processes
- ✓Class A cosmetic part surface — no wax transfer, no smearing on drone frame aerodynamic surfaces
- ✓No oven cure required — air-dry between coats, suitable for large drone mold tooling
- ✓Compatible with epoxy, BMI, and cyanate ester — covers all high-performance UAV composite matrices

FAQ
New mold preparation protocol: (1) Clean the mold surface with acetone or MEK to remove all cutting oil, fingerprints, and dust; (2) Apply Coat 1 of mold sealer (if mold is porous gelcoat or low-density tooling board) — wipe on, buff off after 3 minutes; (3) Allow 30 minutes, repeat sealer for 4–6 total sealer coats; (4) Apply Coat 1 of release agent — wipe on thinly with clean lint-free cloth, allow 30 minutes to dry; (5) Repeat for 4–6 total release coats; (6) Apply a light final coat immediately before first layup. After the first mold cycle, inspect the part surface — any sticking areas indicate incomplete sealing and require additional sealer coats on those zones.
