4. Persediaan dan Penyediaan Permukaan

Proper surface preparation is crucial for optimal adhesion and performance.

1. Permukaan Bersih: 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. Suhu dan Kelembapan: 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. Penyediaan Alat: Prepare a standard caulking gun for the 290 mL cartridge. Cut the nozzle to the desired bead size at a 45-degree angle.

5. Arahan Pengendalian (Aplikasi)

Follow these steps for effective application of the sealant:

1. Masukkan Kartrij: Place the prepared 290 mL cartridge into a standard caulking gun.
2. Apply Bead: 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. Perkakas: 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. pengawetan: 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. Penyelenggaraan dan Penyimpanan

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

• Alat Pembersihan: 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.
• Jangka hayat: Refer to the product packaging for specific shelf life information. Properly stored, the sealant maintains its properties for an extended period.

7. Penyelesaian masalah

If you encounter issues during or after application, consider the following common problems and solutions:

• Lekatan yang lemah:
  • Punca: Insufficient surface preparation (dirty, greasy, wet surfaces).
  • Penyelesaian: Ensure surfaces are thoroughly cleaned, dry, and free of contaminants. Consider light abrasion or priming for difficult substrates.
• Pengawetan Perlahan:
  • Punca: Low temperature or low humidity.
  • Penyelesaian: Ensure application is within recommended temperature and humidity ranges. Curing will naturally be slower in cooler, drier conditions.
• Bubbling or Pinholes:
  • Punca: Application on damp surfaces, trapped air, or too thick a bead.
  • Penyelesaian: Ensure surfaces are dry. Apply an even, appropriately sized bead. Tool immediately to release trapped air.
• Kemasan Tidak Sekata:
  • Punca: Improper tooling or delayed tooling.
  • Penyelesaian: Tool the sealant immediately after application using a consistent technique and appropriate tooling agent.
