AXION25 Nano-Ceramic Coating System
Interior Thermal, Condensation & Hygiene Protection for Healthier Buildings
The Hidden Problems Inside Buildings
While most attention is placed on heat coming from outside, many performance and hygiene problems begin inside buildings.
Interior environments—especially air-conditioned or enclosed spaces—often suffer from:
- Cold surfaces meeting warm, humid air
- Persistent condensation on walls and ceilings
- Mold, bacteria, and fungal growth
- Mold could destroy our artefacts, and
deteriorate our health:
- Asthma: increase the risk of developing asthma, especially in children.
- Severe Allergies: People with pre-existing mold allergies or asthma may experience severe reactions.
- Chronic Issue: Prolonged exposure can lead to additional, sometimes serious, health problems.
- Odours and hygiene complaints
- Uneven thermal comfort
- Noise reverberation in large or enclosed spaces
These challenges appear across:
- Shopping malls and retail corridors
- Hospitals, clinics, and care facilities
- Hotels and serviced apartments
- Offices and meeting rooms
- Factories and air-conditioned production floors
- Agricultural buildings such as poultry farms
Over time, condensation and microbial growth reduce comfort, increase maintenance, and undermine operational performance.
What Building Owners and Operators Want
Owners and operators want interior spaces that:
- Lower cooling energy consumption through passive means
- Long-term prevention of mold and surface staining
- Reduced condensation on walls and façades
- Improved indoor comfort and hygiene
- Added benefits such as noise reduction
- Durable, low-maintenance exterior solutions
They need a coating that does more than just look good—one that actively improves building performance.
AXION 25™ — A Multi-Functional Interior Protection Coating
AXION25 is a Japanese nano-ceramic coating system designed to control heat, condensation, and microbial growth on building surfaces.
Unlike conventional paints or chemical anti-mold treatments, AXION25 works through:
- Thermal insulation and heat-shielding
- Condensation suppression
- Physical blocking of mold and bacteria
- Long-term surface stability without chemical leaching
It is a passive, retrofit-friendly solution that improves energy efficiency, hygiene, and comfort at the building envelope level .
“iCT provides the world-wide solutions to mold/mildew related problems by providing 10-years-proven, cost effective and proprietary anti-mold/mildew nano ceramic coating technology from JAPAN.”
Benefits & Performance
AXION25 delivers multiple long-term benefits:
- Reduction of heat gain through exterior surfaces
- Lower cooling energy consumption
- Long-term mold and mildew prevention
- Anti-bacterial surface protection
- Anti-condensation performance
- Noise and sound-damping contribution
- Non-flammable, non-hazardous, zero-VOC formulation
- Service life typically exceeding 10 years
How AXION 25™ Works
AXION25 improves building performance through surface-level physical control, not chemical action.
1. Heat-Shielding & Surface Insulation
AXION25 contains densely packed hollow nano-ceramic spheres that:
- Reduce heat absorption on exterior surfaces
- Minimise temperature fluctuation between air and wall
- Slow heat transfer into interior spaces
This lowers internal heat gain and reduces air-conditioning load.
Hollow nano-ceramic spheres, < 0.5um
2. Anti-Condensation Control
Condensation is the root cause of mold growth.
AXION25:
- Suppresses dew point formation on walls
- Keeps surfaces dry and thermally stable
- Prevents moisture accumulation even in high humidity
Dry surfaces mean mold and bacteria cannot thrive.
3. Mold & Bacteria Prevention (Without Chemicals)
Instead of chemical biocides, AXION25:
- Forms a dense ceramic barrier
- Blocks spores and bacteria from anchoring
- Maintains effectiveness without UV or light activation
Independent testing confirms strong suppression of mold and harmful bacteria over long periods .
Added Benefit: Sound & Noise Reduction
Beyond thermal and hygiene control, AXION25 also contributes to sound insulation.
The nano-ceramic layer:
- Dampens vibration at the wall surface
- Reduces sound transmission through building envelopes
- Improves indoor acoustic comfort
This is especially beneficial for:
- Buildings near traffic or industrial zones
- Residential and hospitality properties
- Schools, healthcare, and wellness facilities

Special Application Case: Poultry Farms & Livestock Facilities
AXION 25 is also highly effective in poultry farms and livestock housing, where thermal comfort, hygiene, and operational efficiency directly affect productivity.
Key Benefits in Poultry Farms
1. Improved Temperature Control
- High blackbody emissivity (~92%) helps regulate interior temperatures
- Reduces heat stress, especially during hot seasons
- Supports healthier, calmer poultry conditions
2. Reduced Energy Costs
- Improved thermal behaviour enhances heating and cooling efficiency
- More stable temperatures reduce energy consumption
- Lower operational costs for climate control
3. Utilisation of 10-Micron “Growing Rays”
AXION 25 emits thermal radiation in the 10-micron wavelength range, which is widely recognised as a beneficial nurturing wavelength for plants and animals.
This wavelength:
- Supports body temperature regulation
- Improves metabolic efficiency
- Promotes healthier growth in chickens
- Enhances overall physical condition and vitality
4. Long-Term Hygienic Environment
- Anti-microbial and anti-fungal properties prevent pathogen growth
- Reduces mold in walls and ceilings
- Protects poultry health and reduces disease risk
5. Simplified Maintenance
- Mold prevention reduces cleaning frequency
- Less labour and lower maintenance cost
- More stable and predictable farm operations
6. Improved Feed Quality
- Cleaner environments prevent feed deterioration
- Reduced contamination and wastage
- Higher economic efficiency and safer feed supply
7. Better Working Environment
- Easier cleaning and sanitation
- Improved staff efficiency
- Healthier and more comfortable working conditions
8. Increased Egg Production & Meat Quality

Frequently Asked Questions
A nano-ceramic coating that prevents mold and bacteria by controlling heat, condensation, and surface diffusion.
A photocatalyst is a substance that generates catalyst activity using energy from a light. Titanium dioxide is the typical material used. However, it will volatilize after 2 to 5 years, and condensation will occur where mold will grow. It also requires the light where it will be ineffective in a dark location.
Air purifiers are effective in reducing airborne mold spores but are not effective in preventing mold spores from growing.
Although positive pressure is intended to prevent mold from entering a facility, it does not prevent mold from growing. Even with positive pressure, mold can still grow indoors.
AXION25 does not release chemicals or rely on light activation. It works through physical surface control and remains effective long term.
It is classified as the lowest levels of hazardous substance emission and does not contain VOCs (volatile organic compounds).
It can be dyed in various light matte colors. Dark colors are not available as it contains white ceramic materials.
The application process is same as a general water-based paint. 1 container is 14kg and gives 25m to 30 m of surface coverage. It cannot be painted on polypropylene and Teflon coating.
The coating itself is not waterproof, but it can be applied over waterproof systems, such as Radiant+ Coating System from Radiant Climate Technologies.
Yes. It is water-based, low-VOC, non-flammable, and non-hazardous.

Yes. The ceramic layer contributes to sound and vibration damping, improving acoustic comfort.
Control Heat, Moisture, and Comfort at the Surface
Instead of reacting to mold, heat, and discomfort after they appear, prevent them at the building envelope.
