Moisture or debris will significantly reduce adhesion and curing effectiveness. 2.Temperature Sensitivity: Avoid application in direct sunlight or high heat (>30°C), as this accelerates curing and reduces moldability. Ideal working temperature is 15–25°C. 3.Non-Structural Use Only: This is a flexible sealing putty, not a structural adhesive. Do not use for load-bearing repairs or high-pressure pipe interiors. 4.Storage & Shelf Life: Store in a cool, dry place. Reseal unused packs immediately to prevent drying out. Long-term exposure to humidity may affect product integrity. 5.Visual Variations: Slight color differences may occur due to monitor settings. Manual measurement may have ±5mm deviation, which does not affect functionality.
