1. Basic product parameters
Full product name: GATO Nano Tungsten Bronze Powder (Cs WO )
Product introduction: GATO Tungsten Bronze is a new generation of nano-optical functional powder with high near-infrared absorption, high visible light transmittance, and ultraviolet resistance. It is an inorganic thermal insulation nano raw material with comprehensive performance in the fields of coatings, films, plastic modification, and optical thermal insulation, replacing traditional thermal insulation fillers such as ATO, ITO, tungsten oxide, and iron oxide.
Appearance: Dark blue ultrafine nano powder
Primary particle size: 10–30 nm
Specific surface area: 45–65 m2/g
Purity: ≥99.9% (High-purity electronic grade)
Moisture content: ≤0.1%
Ignition residue:
Dispersion characteristics: It can be adapted to the dispersion and modification treatment of the whole system of oil-based, water-based, esters, ketones, and esters (RDP/BDP).
Environmental protection attributes: Halogen-free, heavy metal-free, compliant with RoHS and REACH environmental protection standards
2. Core product features
1. Spectral selectivity, far superior to traditional powders in terms of thermal insulation and light transmission
GATO Tungsten Bronze has a unique energy band structure and selective optical absorption characteristics:
- The blocking rate of near-infrared 780–2500nm is ≥92%, strongly absorbing the heat source of sunlight, with extremely strong thermal insulation and cooling effects;
- High visible light transmittance. The coating/film made is clear, not black or gray, with low haze;
- The full-band blocking rate of the ultraviolet band is ≥99%, with long-term UV aging resistance, anti-yellowing, and anti-powdering.
Under the same light transmission conditions, its thermal insulation performance is 3–5 times that of ATO and 2–3 times that of ITO. It is the core raw material of transparent thermal insulation materials.
2. High temperature resistance, weather resistance, acid and alkali resistance, and stable performance
GATO nano powder has an inorganic stable crystal structure and extremely strong chemical inertness:
- Temperature resistance: Resistant to high-temperature oxidation, with a thermal stability temperature >500℃. It does not decompose or lose efficacy during baking and extrusion modification;
- Weather resistance: It does not decay, fade, or age after long-term outdoor exposure;
- Corrosion resistance: Resistant to acids, alkalis, salt spray, boiling water, and high humidity;
- No migration: The inorganic crystal structure does not precipitate, migrate, or frost, unlike organic thermal insulation additives.
3. Easy to disperse, adaptable to all systems of solvents and resins
The original factory has adopted a powder surface lipophilic/hydrophilic double-modification process, which can be adapted according to the customer's system:
- Water-based system: Directly sand and disperse in pure water or alcohol-water systems;
- Oil-based system: Compatible with ketones, esters, aromatics, and alcohols;
- Flame-retardant system: Adaptable to the RDP and BDP ester flame-retardant solvent systems;
- Resin compatibility: Compatible with acrylic, polyurethane, epoxy, silicone, PC, PET, ABS, and PVC.
Lipophilic modified powder/hydrophilic modified powder can be customized according to customer needs, eliminating problems such as agglomeration, coarsening, high haze, and poor light transmission.
4. Extremely low addition amount, high cost-performance ratio
GATO powder has high thermal insulation efficiency. A thousandth-level addition amount can achieve excellent thermal insulation effects:
- Coating system: An addition amount of 0.3%–1.2% can achieve high thermal insulation and high light transmission;
- Film/plastic modification: 0.15%–0.8% can meet the standard;
Compared with traditional thermal insulation powders, it uses less, the paint film is more transparent, the formula is more stable, and it does not affect the mechanical properties of the substrate.
5. High purity, no impurities, stable batches, suitable for mass production
The high-purity synthesis process results in extremely low metal impurities, no black spots, no coarse particles, and consistent batch color differences. It is suitable for mass production on high-demand assembly lines such as optical films, automotive paints, household appliances, new energy, and flame-retardant modification.
3. Comparison of product core advantages (industry benchmarking)
1. Compared with ATO powder: Higher light transmission, lower haze, 3 times stronger thermal insulation, less likely to have blue haze, and better weather resistance;
2. Compared with ITO powder: Great price advantage, better infrared absorption, no need for high doping, and wider adaptable processes;
3. Compared with tungsten oxide and titanium oxide: Selective light transmission and thermal insulation, not black as a whole, with less light transmission loss;
4. Compared with organic thermal insulation agents: High temperature resistance, no migration, no yellowing, better weather resistance, and compatible with flame-retardant systems.
4. Widely used industry scenarios
1. Transparent thermal insulation coating system
Architectural glass thermal insulation paint, PC daylighting panel thermal insulation coating, outdoor weather-resistant transparent topcoat, metal transparent thermal insulation baking paint, self-drying thermal insulation coating.
2. Optical film industry
PET thermal insulation film, PC light-transmitting thermal insulation board, optical anti-UV film, display high-temperature protective film, outdoor weather-resistant functional film.
3. Engineering plastic modification
PC/ABS transparent modification, acrylic thermal insulation modification, household appliance light-transmitting plastic parts, new energy flame-retardant thermal insulation plastic, car lamp PC anti-UV modification.
4. Ink printing industry
High-temperature resistant transparent thermal insulation ink, glass printing thermal insulation coating, instrument panel light-transmitting functional ink, outdoor weather-resistant printing ink.
5. Flame-retardant and thermal insulation composite system
Combined with RDP and BDP ester solvents to make a dual-functional slurry of flame retardancy and thermal insulation, widely used in electronic flame-retardant coatings and new energy protective materials.
5. Instructions for powder use technology
1. Dispersion method
Mix the dry powder with the corresponding solvent/resin, and the nano-transparent state can be achieved through high-speed stirring + sanding;
Recommended sanding fineness: ≤50nm, with high light transmission and low haze of the finished product.
2. Addition ratio
Regular coatings: 0.3%–1.2%
Film/plastic: 0.15%–0.8%
High thermal insulation requirements: 1.2%–2.0%
3. Adaptable processes
Adaptable to spraying, roller coating, curtain coating, screen printing, extrusion modification, coating production, and high-temperature baking processes.
4. Storage conditions
Store in a dry and sealed place, protect from moisture, and store at room temperature away from light;
The powder has extremely weak moisture absorption, and its performance does not decay after normal storage for 12 months.
6. Supply and quality guarantee
1. Stable mass production and supply
It has a full set of production lines for powder synthesis, high-temperature crystallization, and surface modification. The monthly production of high-purity GATO powder is stable at the ton level, with no risk of supply interruption.
2. Technical support
Provide guidance on powder dispersion technology, formula debugging, haze optimization, anti-agglomeration solutions, and technical support for full-system adaptation.
