Manta SC-300 Silicone Rubber Waterproofing Coating

Manta SC-300 is a high-build, colored silicone rubber waterproofing coating. Formulated from advanced elastomeric siloxane polymers, it cures to form a highly resilient, seamless, and completely waterproof rubber membrane.

Unlike traditional coatings, Manta SC-300 exhibits a unique micro-penetration capability (up to 0.3mm) into porous substrates like concrete and mortar, establishing an inseparable mechanical bond. This completely eliminates the lateral water migration (water tracking) common in traditional sheet membranes.

Features

• Unmatched Weatherability: Harnesses the inherent UV stability of silicone. It withstands extreme high and low-temperature fluctuations without degrading, chalking, or cracking.
• Exceptional Elasticity & Seamlessness: Forms a fully continuous, highly elastic rubber membrane that stretches and recovers, easily accommodating severe structural movement.
• Multi-Substrate Adhesion: Uniquely bonds with aggressive tenacity to a wide variety of challenging building materials, including concrete, mortar, timber, ceramics, glass, and metals (aluminum/steel).
• Aesthetic & Eco-Friendly: Available in various architectural colors to enhance building aesthetics. Formulated as a green, non-toxic, and odorless coating.
• Easy & Safe Application: Single-component (1K) cold-applied liquid. Easy to roll, brush, or spray, ensuring safe and highly efficient installation.

Manta SC-300 is an extremely versatile waterproofing solution, particularly excelling in exposed environments and complex geometries:

1. Exposed Roofs & Metal Structures:

Direct waterproofing and UV protection for new/old concrete roofs, curved tiles, and glazed tiles.

Exceptional adhesion for metal roofs (corrugated steel) and solving waterproofing/sun-proofing issues on aluminum balconies and window canopies.

2. Water Containment & Substructures:

Comprehensive waterproofing for swimming pools, potable water tanks, fish ponds, and wastewater treatment facilities.

Excellent for damp environments like kitchens, bathrooms, basements, and garages.

3. Complex Architectural Shapes:

Ideal for special architectural features, domes, and structures with complicated details where sheet membranes cannot conform.

4. Heavy-Duty Civil Engineering:

Long-term waterproofing for granaries, warehouses, industrial plants, bridges, tunnels, and civil defense projects.

Application Guidelines

• Surface Preparation: Substrates must be structurally sound, clean, and free from dust, oil, and loose debris. Smooth surfaces (like glass or aluminum) should be cleaned thoroughly to ensure optimal silicone adhesion.
• Application Method: Apply the coating evenly using a roller, brush, or airless sprayer. Apply in multiple thin coats rather than one thick coat to ensure proper curing and maximum performance.
• Subsequent Finishes: The fully cured silicone membrane is highly compatible with subsequent architectural finishes, making it ideal for areas requiring external tiling or plastering.
