Automotive rubber seals—from weatherstripping on doors to intricate engine compartment gaskets—are the unsung heroes of vehicle performance. They constantly face a brutal environment: aggressive vibration, extreme thermal expansion and contraction between rubber and metal/plastic, and exposure to oils, fuels, and moisture. A failed seal leads to leaks, noise, reduced efficiency, and costly component damage.
Don’t let a failing seal compromise noise cancellation or critical fluid containment.
INCURE GapFill™ D96 General-Purpose Rubber Bonder
The INCURE GapFill™ D96 is a high-performance cyanoacrylate specifically formulated to provide immediate, strong adhesion to common elastomer substrates like EPDM, Neoprene, SBR, and Natural Rubber. Its optimized medium viscosity allows for controlled application, ensuring a strong, durable bond line that is also clear.
| Feature & Benefit | Technical Insight for Automotive Rubber Seals | Conversion Value |
| Rubber-Specific Formulation | An Ethyl Cyanoacrylate base optimized to react quickly with the surfaces of low-surface-energy elastomers, achieving a fixture time of just 30 seconds. | Maximize Uptime: Get rubber seals secured, installed, and ready for the next assembly step in seconds. |
| Exceptional Shear Strength | Cures to a formidable shear strength of 3,600 psi, ensuring the seal will not peel or shift even under high dynamic stress. | Unbreakable Bond: Guarantee your seals stay in place against door slams, road shock, and high-pressure differentials. |
| Clear, Invisible Bond Line | Dries to a clear finish, maintaining the aesthetic quality of visible components like window or door seals. | Precision Finish: Achieve professional-grade repairs and assembly without visible, messy glue lines. |
| Medium Viscosity (300 cP) | Provides controlled flow, preventing the adhesive from running off vertical surfaces while still allowing it to fill minor surface imperfections. | Clean Application: Eliminate waste and ensure the right amount of adhesive is applied right where you need it. |
Application Steps: Attaching Automotive Rubber Seals for Maximum Durability
- Preparation (Clean & Dry): The key to bonding rubber is surface readiness. Use a cleaner (like isopropyl alcohol or acetone) to degrease and remove mold release agents, oils, or dust from both the rubber and the mating surface (metal/plastic). Wait until surfaces are completely dry.
- Application: Apply a thin, uniform bead of GapFill™ D96 to one of the surfaces. Due to the fast fixture speed, apply quickly and only cover the area you can assemble immediately.
- Assembly: Immediately press the rubber seal onto the mating substrate. Hold the components firmly together for the 30-second fixture time to ensure optimal bond formation.
- Curing Time (Full Strength): While the parts are fixtured in 30 seconds, allow the adhesive to reach full operational strength. For maximum resistance to vibration and temperature changes, allow a full 24 hours before exposing the automotive part to harsh operational conditions.
Stop risking performance losses due to weak, unreliable rubber bonds.
