Description

Applications
– Interior/exterior building joints
– Water-exposed joints (e.g., pools, water tanks)
– Wall-to-ceiling joints
– Precast concrete joints
– Specialized environments: Cold storage, power plants, wastewater treatment plants, docks, potable water tanks (no adverse effects on drinking water).

 

Key Advantages
✔ Exceptional adhesion to diverse materials
✔ Weather/UV-resistant – withstands extreme sunlight
✔ High abrasion resistance
✔ Flexibility across a wide temperature range (-50°C to +80°C)
✔ Chemical solvent resistance (including petroleum)

 

Coverage
Calculated based on joint volume and sealant density (1.2 g/cm³).

 

Application Guide
1. Surface Prep:
– Remove oil, dust, moisture, and loose particles.
– For enhanced adhesion, apply a primer to joint surfaces.

2. Mixing (Two-Component Version):
– Blend Parts A + B thoroughly using a low-speed mixer.
– Apply within 40–50 minutes via trowel or injection pump.

3. Single-Component Version:
– Inject directly from cartridges using a sealant gun.

Critical Notes:
⚠ Clean tools before use.
⚠ Use mixed sealant within 30–40 minutes.
⚠ Wear gloves/safety goggles during handling.
