Product Overview
ALTIC 011 Vermiculite is a cementitious fireproofing and thermal insulation coating specially formulated for use on structural steel, metal, and concrete wall surfaces. Developed by UGAM Technology, it is a high-performance fire protection material conforming to BS EN and ASTM standards. This product is designed to withstand extreme conditions, ensuring optimal safety in industrial, commercial, and construction applications.
ALTIC 011 Vermiculite is available in two grades — Internal Grade and External Grade, both offering excellent adhesion, durability, and protection against heat transfer, fire, and corrosion.
Composition and Type
- 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.
Applications
ALTIC 011 Vermiculite is recommended for use in:
- Industrial plants and factories
- Power stations and refineries
- Steel structures, beams, and columns
- Commercial buildings and fire-rated enclosures
- Tunnels, warehouses, and workshops
- Fire-rated walls, ceilings, and soffits
The coating ensures extended protection for structures that require compliance with fire safety standards and long-term temperature resistance.
Surface Preparation
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 ALTIC 011 Primer if required.
- For Galvanized Steel: Use an etch primer before applying ALTIC Vermiculite Primer.
- For Aluminum Surfaces: Treat with an etch primer followed by ALTIC 011 Primer.
- For Concrete: Ensure the surface is clean, free of dust, and dry.
Proper surface preparation ensures strong adhesion and long-lasting fire resistance.
Application Method
ALTIC 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.
Recommended Equipment:
- Spray machine with adequate pressure control
- Mechanical stirrer for mixing
- Protective mesh (for certain structural applications)
Trowelling can be done if a smoother finish is desired, though “as-sprayed” texture is recommended for maximum performance.
Reinforcement Guidelines
In most cases, reinforcement is not required. However, mesh reinforcement is recommended when:
- Web depth of steel exceeds 650 mm
- ALTIC Vermiculite coating thickness exceeds 50 mm
- Surfaces are exposed to vibration or external weathering
Use galvanized wire mesh (50 mm hexagonal, 19 gauge) for internal applications, and plastic-coated galvanized mesh for external applications.
Environmental Conditions
- Minimum application temperature: 4.5°C (40°F)
- Maximum recommended temperature: 30°C
- Ensure good ventilation for at least 24 hours post-application to allow drying.
- Avoid exposure to frost or direct rainfall for 24 hours after application.
ALTIC 011 is designed for natural curing, requiring no additional curing agents.
Fire Protection & Performance
ALTIC 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.
Fire Ratings:
- Provides up to 240 minutes (4 hours) of fire resistance, depending on thickness.
- Tested up to 550°C and 600°C failure temperatures for structural steel.
- Complies with ASTM E-119, E-84, and E-662 standards for fire endurance and smoke density.
Thermal Performance:
The vermiculite composition ensures excellent insulation, reducing heat transfer and maintaining substrate integrity under high temperatures.
Advantages of ALTIC 011 Vermiculite
- High fire resistance for up to 4 hours
- Lightweight, easy-to-apply spray formulation
- Excellent adhesion on steel, metal, and concrete
- Corrosion protection due to alkaline pH (around 12)
- Long service life with low maintenance
- Environmentally friendly and asbestos-free
- No additional curing required
- Available for both indoor and outdoor applications
Storage and Shelf Life
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.
Quality Control and Standards
Manufactured under strict ISO 9001 and ISO 14001 quality management systems, each batch of ALTIC 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 Guidelines (Indicative)
Thickness of the coating depends on the required fire rating and structural design.
For example:
- 1-hour fire protection: 10–15 mm
- 2-hour fire protection: 20–30 mm
- 3-hour fire protection: 35–45 mm
- 4-hour fire protection: 50–60 mm
More detailed thickness charts are available in the UGAM Technical Manual.
Maintenance
In case of damage, abrade the area back to a clean, sound surface. Reapply fresh ALTIC 011 Vermiculite mixture over the affected area.
Conclusion
ALTIC 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.
