室内環境対応型水性エマルジョンペイント OPTIMUS INTERIOR PAINT 可視応答型光触媒 内装用 高性能光触媒エコ塗料
オプティマスインテリアペイント6つの特徴
- Thermal Barrier
- Air conditioning occupies a significant portion of electricity used in factories. The microcapsules concentrated on the paint surface of OPTIMUS block off the air from the outside, and therefore, shutting off the cold air in the winter, and hot air in the summer, contributing to a large reduction of the electricity used for air conditioners.
- CO2 reduction
- A massive CO2 emission is said to be the cause of global warming. OPTIMUS has an excellent thermal blocking and insulation effects, and therefore, dramatically improves the efficiency of air conditioners, enabling to reduce the electricity needed for air-conditioning, and thus, consumption of oil and other energy resources, which may contribute to the reduction of CO2 emission.
- Air purification
- Nitrogen oxide (NOx) and volatile organic compounds that float in the air, may be chemically altered to become a hazardous substance, which might affect human body. OPTIMUS with its photocatalyst function absorbs and removes nitrogen oxide (NOx) and volatile organic compounds from the air, and thus, keeping the air clean.
- Long lasting
- Maybe you have given up trying to keep the exterior wall clean because the paint applied would be eventually tainted anyhow with all kinds of undesirable substances. OPTIMUS with its photocatalyst function degrades and removes organic compounds and viruses from the exterior wall, which will eventually be washed out by the rain, and therefore, keeps the exterior wall white.
- Excellent weather resistance
- Cracks and other trouble on the paint layer not only cause functional problems, but also cause disfigurement requiring repainting. OPTIMUS, which makes the best use of our longtime paints manufacturing technology, prevents cracking on the paint surface, and is highly resistance to water, and thus, requires less frequent repainting.
- Easy to apply
- You may be thinking that a paint with such various features involve various precautions when applying it. Though, OPTIMUS is a multi-functional paint, it only requires 2 layers of paint like any other monolayer paints.
How does OPUTIMUS INTERIOR PAINT help maintaining the room temperature?
A greenhouse gas is a generic term for the gases that exist in the Earth's atmosphere, which tend to absorb the thermal energy from the sun and keep it within the atmosphere instead of releasing it to outer space, and thus, a greenhouse effect. Due to an increase of such greenhouse gas (especially, CO2), the global warming is steadily on its way.
OPTIMUS to reduce the urban heat island effect!
In cities with asphalt-paved roads, a massive thermal emission is released from air conditioners, causing outstanding increase of temperature compared to suburbs; this is called an urban heat island (UHI) effect. Such increased temperature helps increasing the photochemical oxidant which is harmful to the human body, and is also suggested as a potential cause of torrential rainfall. OPTIMUS helps relieving such urban heat island effect.
This is the difference! -- An unique technology that support OPTIMUS
Three special materials help maximizing the heat blocking, self-cleaning, and air-cleaning effects!
A thermal bottle has a structure consisting double layers of glass with vacuum in between which prevents heat transfer so as to maintain the temperature of drinks inside. We focused on this characteristic of vacuum when developing OPTIMUS, and were able to successfully contain microcapsules of 40 to 60 μm in the paint. When OPTIMUS dries out, these microspheres with a lower specific gravity float up to and cover the surface, and obstruct the heat from passing through the wall, shutting off the cold air in the winter, and hot air in the summer, contributing to the energy conservation, enabling to reduce electricity bills for air-conditioning, and at the same time, CO2 emissions.
Nano-size photocatalyst
Photocatalyst is an "environmental clean-up material" that generates, on its surface, a strong active oxygen called the oxide radicals when exposed to ultraviolet rays from sunlight or a fluorescent lamp.
Keeps the base materials from degradation while maintaining the effect
The microcapsules coated with the nano-sized photocatalyst (titanium oxide) degrades and removes organic compounds and viruses from the surfaces when exposed to ultraviolet rays from the sunlight. Conventional photocatalysts mixed in an organic material such as a paint had always been associated with a problem of degrading their own base materials. OPTIMUS contains microcapsules with a lower specific gravity that floats up to and cover the surface, keeping the base materials from degradation, and therefore, fully brings out its photocatalytic action, that is, self-cleaning and air-cleaning effects for a prolonged period.
The hybrid and resilient paint film formed with
an inorganic material using colloidal silica
A colloidal silica is a material in which alkaline silicate (liquid glass) is nano distributed. With the colloidal silica content, OPTIMUS maintains a good balance of resinous contents, and helps forming a strong paint film with a high endurance exceeding that of conventional acrylic silicone resin. Also, the colloidal silica combined to add superhydrophilicity on the paint film further improve the self-cleaning effect of the photocatalyst, bringing out an outstanding staining-resistance and weather-resistance effect.
Here is the difference in 1 year!
Maintains the whiteness forever! An exterior wall coated with OPTIMUS (picture on the left) and a wall without OPTIMUS coating were compared in 1 year. The whiteness on the OPTIMUS-painted wall remained unchanged after 1 year while the wall with no OPTIMUS had stains and discoloration.
Here is the mechanism of self-cleaning.
It degrades and removes dirt from the surface. The OPTIMUS-painted exterior wall absorbed the oil floating near the wall ([1]), and also, organic compounds and viruses on the surface of the oil ([2]), which are degraded along with the oil as the sunlight triggers the photocatalyst contained in the surface layer of OPTIMUS ([3]), and finally the degraded substances are washed out by the rain ([4]).
OPTIMUS WHITE PAINT was developed as a product pertinent to an industry-government-university cooperation.
OPTIMUS was developed under the support of Sakai City, and through cooperative efforts by Osaka Prefecture University, Graduate School of Engineering. The photocatalytic effect characteristic of OPTIMUS, which was developed based on the photocatalytic technology owned by Osaka Prefecture University, has been filed for patent protection, which is currently under review.
Confirmed air-cleaning effect
OPTIMUS with its photocatalyst effect removes nitrogen oxide (NOx) from the air, and thus, keeping the air clean. The NOx concentration in the air around the OPTIMUS-painted surface was compared to that around a surface with no OPTIMUS paint; the NOx concentration around the OPTIMUS-painted surface decreased to zero in 1 day (Based on the results of studies conducted by Osaka Prefectural Institute of Advanced Industrial Science and Technology).
Thermal conductivity test
The thermal conductivity of OPTIMUS was tested; which was 0.08, about 1/20 of concrete, and equivalent to glass-wool insulation for home use (A test conducted by the Japan Paint Industry Association).
Physical properties of OPUTIMUS WHITE PAINT
OPTIMUS is highly regarded worldwide.
The difference in indoor temperature by the heat blocking effect is outstanding; ≦5°C after use of OPTIMUS.
The 2 graphs on the right present the results of comparison between an OPTIMUS painted exterior wall and a regular paint coated wall. While the mean peak temperature in a room with a regular paint-coated wall (figure on the left) reached 37°C, that in a room with an OPTIMUS painted wall (figure on the right) was 32°C, about -5°C lower. The heat blocking effect of OPTIMUS dramatically improves the efficiency of air conditioners.
