10M DIY Self-Adhesive Industrial Roof Waterproof Blue Sealant Tape Roll

• Description:
• This waterproof tape uses six-layer composite tech (anti-aging PO film, aluminized film, PE layer, etc.) and an asphalt-free polymer formula, avoiding asphalt's temperature-related brittleness. It bonds deeply via physical/chemical links for durable waterproofing.
• It blocks water (roof cracks, tile joints), insulates (lowers summer temps, retains winter heat), resists UV, and reduces rain noise. Self-adhesive, it sticks to steel, cement, wood-withstands extreme heat/cold without peeling.
• 30cm×10m per roll (cuttable) enables DIY installation (no tools), saving labor costs. Ideal for roofs, balconies, bathrooms.

• Feature:
• Six-layer composite technology + asphalt-free formula for dual waterproof and aging resistance.
• Multi-layer construction:
• Utilizing a six-layer lamination process consisting of an anti-aging PO polymer film layer + aluminized polymer film + a water-repellent PE polymer soft layer + a high-density chemical fiber water-repellent layer + a modified specialty waterproof adhesive + an elastomeric high-silicon barrier layer, each layer performs a specific function. The PO film prevents oxidation of the aluminum film, while the PE film maintains its waterproofing properties even after aging. The chemical fiber layer provides thermal insulation, and the modified waterproof adhesive (independently developed) withstands harsh climates, preventing drying and debonding, and resists cracking even with long-term exposure.

• Asphalt-free for greater durability:
• Eschewing traditional asphalt-based adhesives, this non-asphalt sealant, made from polymer raw materials, overcomes the drawbacks of asphalt-based materials, such as brittle cracking and weak adhesion due to temperature fluctuations. Combined with a large amount of negative electron ions and creep penetration, it penetrates deep into the pores of the substrate, forming a dual bond of physical penetration and chemical cross-linking, firmly adhering to surfaces such as color-coated steel tiles, roofs, and walls, for a long-lasting waterproof effect.

• Waterproof and heat-insulating, providing comprehensive protection in various scenarios.
• Strongly waterproof and impermeable:
• The surface waterproof coating and multi-layer water-repellent structure completely block water penetration, effectively sealing leaks from roof cracks, color steel tile joints, and wall holes, effectively blocking rain, dew, and even humid environments.
• Thermal insulation and temperature control + UV protection:
• Contains PE sun-resistant film and synthetic water-repellent fabric, combined with non-reflective chemical insulation technology, to reflect UV rays and reduce heat conduction-lowering indoor temperatures in summer and assisting with insulation and reducing heat loss in winter. The PO film and aluminized film also resist UV aging, preventing performance degradation after prolonged exposure to sunlight and extending the tape's lifespan.

• Additional Features:
• It also provides sound insulation, reducing the noise of rain hitting the roof and color steel tiles, meeting the multiple needs of waterproofing, heat insulation, and soundproofing.
• Strong adhesion and weather resistance, long-lasting durability, suitable for extreme environments
• Superior Adhesion:
• The self-adhesive design requires no additional glue and adheres tightly to a variety of substrates, including color-coated steel tiles, cement, metal, and wood. Its high tensile strength prevents peeling or warping after application.
• High Heat and Weather Resistance:
• It withstands extreme heat without losing adhesion or deforming. It also resists aging and high and low temperature cycling, remaining stable in complex climates such as rain, snow, frost, and direct sunlight, ensuring a long service life and reducing the need for frequent repairs.

• DIY self-adhesive + large size, easy and low-cost installation
• No professional tools required:
• The self-adhesive material allows you to apply directly after removing the barrier layer. Without a professional installation team, you can repair roof and wall leaks yourself, saving labor costs.
• Large Coverage:
• Measuring 30cm wide by 10m long, a single roll covers a large area and can be cut to size. Suitable for repairing large or small gaps on roofs, balconies, bathrooms, and prefabricated steel buildings, it maintains competitive pricing while maintaining practicality and affordability.
