Product Advantages
Exhibits good adhesion to different substrates, ensuring stable and reliable sealing performance.
Maintains airtightness and waterproofing properties under joint movement, vibration, or temperature changes.
Demonstrates good resistance to environmental factors like UV rays and ozone, ensuring stable long-term performance.
Offers clear product classifications, allowing selection of appropriate flowability and modulus types based on project requirements.
Product Features
Adhesion: Forms a stable bond with common building materials such as metal, concrete, glass, and stone.
Airtightness & Waterproofing: The cured layer is dense with low water vapor transmission, accommodating routine joint movement.
Weather Resistance: Resists UV rays, ozone, and natural climatic effects; maintains integrity without easily cracking or powdering over time.

Product Applications
Classification Options:
By Flowability:
Non-Sag (N): For vertical and inclined joints.
Self-Leveling (L): For horizontal joints.
By Modulus:
High Modulus (HM): Suitable for joints with smaller movement.
Low Modulus (LM): Suitable for joints with larger movement.
Application Scope
Construction Engineering: Waterproof sealing for concrete wall panels, roofing, settlement joints, and expansion joints.
Transportation Engineering: Joint sealing for highways, bridges, and airport runways.
Hydraulic Engineering: Leak-proof sealing for tunnels, reservoirs, swimming pools, and water tanks.
Industrial Applications: Oil-resistant sealing for pipe joints and metal structures.
Application Method
Surface Preparation: The application surface must be clean, dry, and free from oil, dust, and loose particles. Primer may be used if necessary.
Mixing (Two-Component): Mix Component A and B thoroughly according to the specified ratio on the package, avoiding air entrapment.
Application:
Non-Sag Type: Apply into the joint using a caulking gun or spatula, then compact and smooth.
Self-Leveling Type: Pour into horizontal joints; it will level naturally.
Curing: Protect the applied sealant from water or contamination until fully cured. Curing time is influenced by temperature and humidity.
Cleanup: Uncured material can be removed from tools using specialized solvents. Cured material requires mechanical removal.
Packaging and Storage
Packaging Specifications: Various packaging forms are available based on user requirements.
Storage Conditions: Store in a cool, dry place away from direct sunlight.
