Product overview
Flocklok 852F is a single-coat adhesive for bonding polyester or nylon flock to elastomer substrates. It is suitable for SBR, CR, NBR, and EPDM and can be integrated into production-line or off-line flocking processes.
Key benefits
- Provides good abrasion resistance on flocked substrates.
- Bonds polyester and nylon flock to multiple elastomer types.
- Performs across a wide range of cure conditions and cures quickly at elevated temperature.
- Compatible with both on-line and off-line production.
Compatible materials and processes
- Flock: polyester or nylon.
- Elastomers: SBR, CR, NBR, and EPDM.
- Processing: directly on the production line or in a separate off-line operation.
Application guidance
Remove dirt, rubber bloom, processing oils, mold-release material, and other contaminants. The adhesive can be supplied by peristaltic pump or pressurized vessel. A typical wet-film thickness is 95–145 μm (3.7–5.7 mil), equivalent to 51–76 μm (2–3 mil) dry film. Elevated-temperature curing is required for optimum bond performance. A typical cure is 2 minutes at 204°C (400°F).
