Package

Cartridge Size: 300ml, 590ml
Available Colors: Clear/Transparent, White, Black, Gray, Customized
Packaging Type: Hard tube, Sausage pack/cartridge
Shelf Life: 12 months from production date (in sealed original container)
Storage Conditions: Store in cool, dry place below 27°C

Step 1: Surface Preparation

Ensure the substrate surface is clean and free from contamination, dust, oil, and loose particles
For better adhesion, surfaces should be dry

Step 2: Application

Cut the cartridge nozzle at a 45° angle to desired bead size
Load cartridge into a standard caulking gun
Apply sealant from the cartridge evenly onto the joint area

Step 3: Tooling & Finishing

Smooth and finish the sealant before skin formation occurs (within 10-15 minutes)
Use a spatula or finger (moistened with soapy water) to tool the joint
Remove masking tape immediately after tooling

Step 4: Curing

- Allow adequate curing time before exposing to stress or weather conditions
- Full cure typically achieved in 7-21 days depending on joint depth and environmental conditions

Tips

For Best Results:

Use backer rod or bond breaker tape for joints deeper than 12mm to control joint depth and ensure proper width-to-depth ratio (2:1 recommended)
For maximum adhesion, conduct adhesion tests on actual substrates before large-scale application
Avoid three-sided adhesion which can cause joint failure
Do not apply in rainy conditions or when rain is expected within 24 hours
Clean tools and uncured sealant with mineral spirits; cured sealant can only be removed mechanically
Wear gloves during application to avoid skin contact
Ensure adequate ventilation during application and curing

Storage Tips:

Keep cartridges in upright position during storage
Once opened, use cartridge within one month for best performance
Refrigeration can extend shelf life but bring to room temperature before use
