・2017～, It started to contract exclusive distributors for IRUV Cut Coat whole in the world.

Stage4） 2021～ : Started to sell Anti-fungal coating as the lowest price in Super Market
industry in Japan.
Started to sell interior insulation system by collaborating 3 products.
= Triple far-infrared cooling / heating system① Developed antifungal heat insulating interior paint and non-combustible heat insulating interior paint for indoor use.
② Started selling materials with training guidance directly to individual houses, small stores, and office users.
= DIY-PRO support plan.
➂ For Japanese supermarkets, we have developed a three-step method of removing mold, killing mold,and preventing mold at the lowest price in the industry from 1800 yen to 2800 yen per square meter.
④A business model that provides a comfortable and healthy space by collaborating 3 far-infrared radiation products:
far-infrared radiation air conditioner “THEAR”, IRUV cut coat (far-infrared heat insulation coat) for window glass,and far-infrared radiation interior paint. It built a model room where you can experience the “triple infrared cooling /heating system" in various parts of Japan.

Stage5） 2022～ Started New business model, “Challenge Energy Saving 40 “
for chain stores from Japan. Plan to expand to the global market from now on.
For the chain store industry, as an energy-saving measure around air conditioning and outdoor units, we havestarted an initiative aiming for 40% energy saving by collaborating with the following 3 products.
① 25% with IRUV cut coat on window glass, ➁ 15% with heat insulating painting around the outdoor unit,
In addition, we have also developed and developed a Triple Guard coating application system, which is a rustprevention, heat insulation measure and anti-dust for folded-plate roofs, for chain stores.
The IRUV Cut Coat application results of more than 1100 stores nationwide from November 2019 to February 2022 in Japan.

Japan's most advanced nanotech product manufacturer
with the world‘s No. 1, high performance, multi-functionality, and low cost
１、Anti-Heat nano-coating for window glass= IRUV Cut Coat Hyper-SP
20% to 30% reduction in air conditioning costs by thermal insulated coating on window glass of existingbuildings = CO2 emission reduction by energy saving effect.
Sketch has developed a liquid insulation glass coat that can be easily coated on window glass with a roller.
It improves the effect of infrared rays cut rate of 80% or more and ultraviolet rays of 99% or more just bycoating on existing window glass. Durability is 15 years, On the contrary, general window film is 5 to 10 years
durable. It lasts much longer than window film. It is the only one in the world that can be easily applied towindow glass by roller application;, so anyone can learn coating techniques by online or offline training.
Sketch's IRUV cut coat occupies 80% of the market share in Japan and is an energy-saving product with a sales
record all over the world. In Japan, we successfully applied 1000 or more of chain stores during 2019~2022 inJapan.

2、Rust Proof, Anti-heat painting for the Surrounding Outdoor unit of chiller and Air-conditioning= Rustshield（Anti-Rust） & Thermo ECO Shield（Anti-Heat）＆Super Glass Barrier（Anti-dust ）Developed Rust shield + Thermo ECO Shield + Super Glass Barrier= Triple Guard coating application
system that reduces air-conditioning costs by15% or more annually by applying rust-proof, heat-insulating,and antifouling coats for corrugated metal roof, outdoor units and their surroundings.
Generally, Rust-Proof Market, Heat-Shielding Market, Anti-fouling Market are all different business.
If Customer wants to solve 3 problems of them once, It will be huge cost because each solutions are
conducted by each special painting applicator companies.
On the contrary, Customer can't request one applicator company to solve 3 problems once by low cost.
But Sketch can solve problem to supply low price due to develop each products by one company.
It means Applicator that bought products from Sketch can suggest low application cost for the customer.
Our Application Target is outdoor unit and surroundings installed on food market like Franchise Super
Market for example because They use high expense for electricity bill every month due to using freezer,
refrigerator, air conditioning for 24 hours everyday. We apply the surface of outdoor unit and installment
ground under the outdoor unit, It is small area to apply because we don’t focus on all roof area.
Of course, if customer has a budget for painting on the whole roof, It will be much better to perform thesolution. But it will be expensive. But We propose to apply only surrounding outdoor unit.

３、 Anti-Static, Super Hydrophilic Self-Cleaning Coat= Super Glass Barrier
1998, TOTO announced HYDROTECT, the photocatalyst, hydrophilic antifouling coat usingtitanium oxide, this has opened a new market in antifouling market of building, and the car.
However, China, Southeast Asia, the Middle East, there are dirt and carbon sand lot, thephotocatalyst coating using titanium oxide, have little effect.. So Sketch, has developed a coatingmaterial of super-hydrophilic antistatic anti-fouling self-cleaning by using a tin oxide SnO2 andSiO2 silica. We develop products that flow down with running water and rain in the superhydrophilic it is difficult to stick the dirt.. And firmly adhered for inorganic material, outer wall, tile,and glass, there is a self-cleaning antifouling effect for long term. This product can be long-lastingcoating one time, will be the main product of the aesthetic maintenance of the building in thefuture. We have a construction record of 10 million m2 all over the world.
Especially in China, Southeast Asia, and the Middle East, where there is a lot of exhaust gas anddust, the ultra-hydrophilic self-cleaning coat, which has an antistatic function, makes it difficult for
dirt to adhere from the beginning and makes it easy to remove the dirt, is ideal. In 2019,４、 Patent No. 7146223; acquired on September 26, 2022.
Antistatic coatings, antistatic glass substrates, and solar panels”

We have sold more than 10 million square meters of antistatic superhydrophilic self-coat including "SuperGlass Barrier" for exterior walls for more than 20 years.
However, in high-temperature, low-humidity environments such as desert areas, where there is little rainfall,
the antistatic performance deteriorates, and we have faced problems especially with solar panels.
We have now succeeded in developing a coating agent that exhibits strong antistatic performance of 10Ω4,high adhesion, high weather resistance, and high chemical resistance while maintaining a certain level oftransparency by binding SWCNTs.
In addition, since the strong conductivity of SWCNTs can be applied to the back sheet to further dissipate heat,we will conduct many demonstration tests in the future.
