Description
CONAP PR-1167 primer is a single-component urethane primer used before bonding or casting polyurethane compounds onto hard-to-bond surfaces. It is a strong fit for electronics, potting, and molded-part work where cured urethanes, neoprene rubber, or cadmium-plated metals need a cleaner, more dependable bond line.
Key Features and Benefits
- Single-component formula cuts mix steps at the bench and helps keep prep work consistent from shift to shift.
- Low 75 cps viscosity at 25 degrees C wets surfaces quickly, which helps build better contact before the urethane is poured or bonded.
- 58 percent solids content leaves a useful primer film without turning brittle after cure.
- Flexible cured film helps support bonded assemblies that see vibration, flex, or thermal movement.
- Air-dry window of about 1 to 2 hours supports a practical workflow for repair, potting, and production runs.
- Can be used with room-temperature or elevated-temperature cure schedules based on the polyurethane system being applied next.
Common Applications for CONAP PR-1167 primer
- Priming metal housings before polyurethane potting in electrical assemblies
- Bond prep for cured urethane parts that need overmolding or secondary bonding
- Neoprene rubber surface prep in sealing and insulation work
- Cadmium-plated metal prep for aerospace and defense-style repair tasks
- Conformal coating and encapsulation workflows where adhesion must stay reliable over time
Compatible Substrates
- Cured polyurethane
- Liquid polyurethane systems
- Neoprene rubber
- Cadmium-plated metals
- Prepared metal and coated assembly surfaces that require primer before urethane application
