Sikaflex 295UV is a one-component, moisture-curing polyurethane adhesive engineered specifically for bonding polycarbonate and acrylic windows in marine applications. Its UV-resistant formulation prevents degradation from prolonged sun and saltwater exposure — making it the right choice for hatches, portlights, and transparent deck fittings where standard sealants break down over time. High thixotropy means it stays in place on vertical and overhead surfaces without sagging, and it cures to a flexible, durable elastomer that accommodates the movement and vibration typical of a working boat.
Key Features
- UV-resistant formulation — resists degradation from direct sunlight and saltwater exposure
- Bonds and seals polycarbonate and acrylic windows to fiberglass, aluminum, and structural members in one step
- One-component moisture-curing polyurethane — no mixing required
- High thixotropy for excellent gap-filling and no-sag performance on vertical surfaces
- Fast tack-free time for efficient installation
- Sandable and paintable after cure
- Cures to a flexible, high-quality elastomer (Shore A hardness)
- Format: 11 oz. (310 ml) cartridge — compatible with standard caulking guns
- Color: White | SKU: 884-295UVWH
Compatible Applications
- Bedding and bonding polycarbonate and acrylic portlights, hatches, and windows
- Bonding transparent deck fittings and glazing to fiberglass or aluminum frames
- General marine sealing applications where UV resistance is required
- Above and below the waterline use
- Not recommended as a structural adhesive for high-load joints — use Sikaflex 291 for general-purpose bonding and sealing
Parts Desk Insights
Best Use Case: The 295UV is the right call any time a customer is bedding or replacing a polycarbonate or acrylic portlight or hatch — particularly on boats with significant sun exposure. Standard polyurethane sealants yellow and degrade under UV, which compromises both the bond and the appearance of the window installation. The 295UV holds up where others fail. For general-purpose marine bonding and sealing without the UV-specific formulation, see Sikaflex 291 White 11 oz. or Sikaflex 291 Black 11 oz. For smaller jobs or tight spaces, the Sikaflex 291 White 70 ml mini sausage is a practical option.
