Rubber weatherstripping, seals, and gaskets are essential components in everything from automotive doors to HVAC units and industrial enclosures. Their primary function—to seal against air, water, and dust—subjects them to constant flexing, compression, and environmental stress. A standard, rigid super glue will fail quickly, cracking under the constant movement of a door opening and closing or a seal expanding and contracting due to temperature changes. You need an adhesive that cures fast but remains tough and flexible.
Don’t settle for a brittle bond that will crack and leak under dynamic load.
INCURE Gapfill™ D96 General Purpose Rubber Bonder
The INCURE Gapfill™ D96 is formulated specifically to tackle the challenges of elastomers (rubbers). It provides the rapid fixture speed of a cyanoacrylate but delivers a cured bond line with the necessary resilience and elasticity to handle constant flexing and vibration without failing.
| Feature & Benefit | Technical Insight for Your Application | Conversion Value |
| Optimized for Elastomers | Engineered to provide superior adhesion to common weatherstripping materials like EPDM, Neoprene, and Nitrile rubber. | Specialized Grip: Get a reliable, high-strength bond that won’t separate from dynamic rubber substrates. |
| High Flexibility & Toughness | Unlike standard CAs, the cured D96 bond line is tougher and less brittle, capable of withstanding continuous movement, compression, and flexing. | Outlast the Stress: Ensure the weatherstripping holds up to thousands of operational cycles without bond failure. |
| General Purpose Versatility | Bonds rubber to itself, as well as to common substrates like metal, plastic (PVC, ABS), and composite materials often used in frames and enclosures. | One-Stop Solution: Simplify your process with a single adhesive that works across all the components of your seal assembly. |
| Clear Bond Line | Cures to a clear, virtually invisible finish, maintaining the aesthetic quality of visible weatherstripping or sealing applications. | Aesthetic Integrity: Achieve a strong, professional result without unsightly yellowing or opaque residue. |
Application Steps: Bonding Weatherstripping for Durable, Flexible Seals
Preparation (The Foundation): Thoroughly clean both the rubber strip and the mating surface (metal frame, plastic housing, etc.). Use a lint-free cloth and a suitable solvent (like Isopropanol or Acetone) to remove dirt, grease, and any mold-release agents, which are very common on rubber.
Application: Apply a thin, continuous bead of INCURE Gapfill™ D96 to one of the surfaces. Remember: less is more with cyanoacrylates; applying too much will slow the cure time and weaken the final bond.
Assembly: Immediately press the weatherstripping firmly into place. Apply even, medium pressure for 10 to 20 secondsto achieve initial handling strength. If bonding large, long strips, work in small sections.
Curing Time (Achieving Full Resilience): While you’ll have instant fixture, allow the bond to cure for a full 24 hours at room temperature before subjecting the weather stripping to full operational movement, water immersion, or temperature extremes.
Stop wasting time with temporary fixes. Use a permanent bond built for flexibility.
