3. 製品の説明

Bostik Fast Set 940 FS Adhesive/Sealant is a high-performance, one-component, moisture-curing, silyl modified polymer. It is specifically formulated for marine applications, suitable for use both above and below the waterline. This sealant is ideal for bonding and sealing a variety of porous and nonporous materials, including glass, PVC, wood, aluminum, steel, and brass. It offers excellent flexibility, fast-skinning properties, and strong resistance to UV exposure, ensuring durable and long-lasting results in harsh marine environments.

The product is supplied in a 290 mL cartridge and is white in color.

4. セットアップと表面の準備

Proper surface preparation is crucial for optimal adhesion and performance.

1. 表面をきれいにする: Ensure all surfaces to be bonded or sealed are clean, dry, and free from dust, grease, oil, old sealant, and other contaminants. Use an appropriate solvent cleaner if necessary, and allow it to evaporate completely.
2. Roughening: For certain non-porous materials like metals or plastics, light abrasion (sanding) may improve adhesion. After roughening, clean the surface again to remove any debris.
3. Priming (Optional): While Bostik 940 FS generally offers excellent adhesion without primers, specific challenging substrates or critical applications may benefit from a compatible primer. Consult Bostik technical data sheets for primer recommendations if needed.
4. 温度と湿度: Apply the sealant in conditions within the recommended temperature and humidity ranges (typically 5°C to 35°C and 40-70% relative humidity) for best results.
5. ツールの準備: Prepare a standard caulking gun for the 290 mL cartridge. Cut the nozzle to the desired bead size at a 45-degree angle.

5. 操作手順（アプリケーション）

Follow these steps for effective application of the sealant:

1. カートリッジを挿入します: Place the prepared 290 mL cartridge into a standard caulking gun.
2. ビーズを付ける: Apply a continuous, even bead of sealant to one of the prepared surfaces. For bonding applications, ensure sufficient coverage. For sealing, fill the joint completely.
3. ツーリング： Tool the sealant immediately after application to ensure good contact with the substrate and to achieve a smooth, professional finish. Use a suitable tooling tool or spatula moistened with a compatible solvent (e.g., mineral spirits) or water (for water-based tooling agents).
4. Assembly (for bonding): If bonding, bring the two surfaces together within the sealant's open time (skinning time). Apply firm, even pressure to ensure full contact.
5. 硬化: The sealant cures by reacting with atmospheric moisture. Skinning time is fast, but full cure can take several days depending on bead thickness, temperature, and humidity. Avoid disturbing the bond or seal during the initial curing phase.
6. Above/Below Waterline: This product is suitable for both above and below waterline applications. For below waterline, ensure the sealant has achieved sufficient cure before immersion.

6.メンテナンスと保管

Proper maintenance and storage extend the life of the product and ensure future usability.

• 清掃用具: Clean tools and equipment immediately after use with a suitable solvent (e.g., mineral spirits or xylene) before the sealant cures. Cured sealant must be removed mechanically.
• Storage of Unused Product: For partially used cartridges, ensure the nozzle is tightly sealed to prevent air and moisture ingress. Store the cartridge upright in a cool, dry place between 5°C and 25°C.
• 貯蔵寿命： Refer to the product packaging for specific shelf life information. Properly stored, the sealant maintains its properties for an extended period.

7。 トラブルシューティング

適用中または適用後に問題が発生した場合は、次の一般的な問題と解決策を検討してください。

• 接着不良:
  • 原因： Insufficient surface preparation (dirty, greasy, wet surfaces).
  • 解決： Ensure surfaces are thoroughly cleaned, dry, and free of contaminants. Consider light abrasion or priming for difficult substrates.
• ゆっくり硬化:
  • 原因： Low temperature or low humidity.
  • 解決： Ensure application is within recommended temperature and humidity ranges. Curing will naturally be slower in cooler, drier conditions.
• Bubbling or Pinholes:
  • 原因： Application on damp surfaces, trapped air, or too thick a bead.
  • 解決： Ensure surfaces are dry. Apply an even, appropriately sized bead. Tool immediately to release trapped air.
• 不均一な仕上がり:
  • 原因： Improper tooling or delayed tooling.
  • 解決： Tool the sealant immediately after application using a consistent technique and appropriate tooling agent.
