HSN CODE: 38160000
SC Vermiculite OPC Cementitious Coating is a thick fireproof coating made using vermiculite or perlite aggregates. It provides passive fire protection by insulating structures and preventing temperature rise. It is widely used in industrial and infrastructure projects. All products are Green Products and are manufactured under ISO 9001:2015 and ISO 14001:2015 standards, ensuring quality, reliability, and environmentally responsible production.
Generic Type: Vermiculite-based cementitious fireproof coating
Form: Single-pack dry powder
Packaging: 25 kg bags
Mixing Ratio: Add water gradually and stir mechanically until a smooth, uniform paste is achieved
Dry Density:
Internal Grade: 400–420 kg/m³
External Grade: 750–800 kg/m³
The formulation is engineered to provide a strong bond with metal and cement surfaces while maintaining a lightweight and porous structure, allowing it to resist fire efficiently by insulating the substrate
SC 011 Vermiculite is recommended for use in:
The coating ensures extended protection for structures that require compliance with fire safety standards and long-term temperature resistance.
Before application, all steel and concrete surfaces must be clean and free from oil, grease, dust, loose rust, or any other contaminants. The following preparation steps are recommended:
For Steel Surfaces: Remove all rust, grease, and mill scale. Use brushes or vacuum cleaners for cleaning. Apply SC 011 Primer if required.
For Galvanized Steel: Use an etch primer before applying SC Vermiculite Primer.
For Aluminum Surfaces: Treat with an etch primer followed by SC 011 Primer.
For Concrete: Ensure the surface is clean, free of dust, and completely dry.
Proper surface preparation ensures strong adhesion and long-lasting fire resistance.
SC 011 Vermiculite can be applied using standard spray equipment. It is built up in layers of 10–30 mm per coat. Successive coats can be applied after the initial set (typically 4–8 hours). The final texture should appear rough and granular.
Trowelling can be done if a smoother finish is desired, though “as-sprayed” texture is recommended for maximum performance
In most cases, reinforcement is not required. However, mesh reinforcement is recommended when:
Use galvanized wire mesh (50 mm hexagonal, 19 gauge) for internal applications, and plastic-coated galvanized mesh for external applications.
SC 011 is designed for natural curing, requiring no additional curing agents.
SC 011 Vermiculite offers superior fire protection as per international testing standards. It has been tested under BS EN, ASTM, and NFPA conditions for flammability, smoke emission, and surface burning.
Thermal Performance:
The vermiculite composition ensures excellent insulation, reducing heat transfer and maintaining substrate integrity under high temperatures.
Store in a cool, dry, and ventilated place, away from direct moisture or sunlight. Keep bags off the ground.
Shelf Life: 12 months in original sealed packaging.
Avoid using bags exposed to water or humidity.
Manufactured under strict ISO 9001 and ISO 14001 quality management systems, each batch of SC 011 is tested for density, consistency, and performance. Every package is traceable by production date and lot number.
A sample area should be applied before full-scale use to ensure consistency and compliance with project specifications.
Thickness of the coating depends on the required fire rating and structural design.
For example:
More detailed thickness charts are available in the UGAM Technical Manual.
In case of damage, abrade the area back to a clean, sound surface. Reapply fresh SC 011 Vermiculite mixture over the affected area.
SC 011 Vermiculite Fireproof Coating is a proven, reliable, and certified solution for fire protection and thermal insulation of structural steel, metal, and wall applications. Manufactured under stringent quality standards by UGAM Technology, it delivers unmatched durability, safety, and ease of application — making it the trusted choice for fire-rated construction and industrial protection.
