"Ruminastar" is a water-based paint that incorporates hollow beads densely filled with a special acrylic emulsion resin and mixed with infrared high-reflective pigments. It excels in durability, weather resistance, adhesion, and elasticity (with an elongation rate of over 250%), providing long-term energy-saving effects. It boasts an astonishing solar reflectance of 92.7% (white) and a thermal conductivity of 0.09 W/(m·k). 【Features】 ■ High insulation performance with a thermal conductivity of 0.09 W/(m·k) ■ Coating film that stretches like rubber ■ Excellent weather resistance with an expected lifespan of over 20 years ■ Adhesion strength approximately four times that of JIS standards ■ Maintains temperature within buildings *For more details, please request materials or view the PDF data from the download section.

We would like to introduce a case study of the "Luminastar" that we handle, which was applied to a project. The construction period was from June 20 to July 5, 2019, with a construction area of 4,000 m2 of a corrugated roof. The effect measurement period was from July 1 to August 25, 2019. As a result, the air conditioning electricity consumption was reduced by 9,860 kWh compared to the previous year, resulting in a reduction effect of 40.6%. The reduction in air conditioning electricity costs amounted to 167,620 yen (calculated at 17 yen/kWh). [Case Overview] ■ Construction Period: June 20 to July 5, 2019 ■ Construction Area: 4,000 m2 (corrugated roof) ■ Effect Measurement Period: July 1 to August 25, 2019 *For more details, please download the PDF or feel free to contact us.

"Ruminastar" is a water-based paint that achieves high heat insulation and thermal insulation properties. By applying it to the roofs and exterior walls of buildings, it reflects solar heat and maintains internal temperatures through a thermos effect. It helps to maintain indoor temperatures, reducing air conditioning loads and improving indoor temperature environments. Additionally, it can be applied while the building is in normal use, and by using it at the timing of building repairs, there is a possibility that it can be accounted for as an expense if it fits the repair costs (Note 1). It enables smart measures against heatstroke. 【Features】 ■ Achieves a solar reflectance rate of 92.7% and a thermal conductivity of 0.09w/(m･k) (Note 2) ■ Realizes a painted surface without cracks, blisters, or peeling due to high elasticity and adhesion ■ Weather resistance is estimated to be over 15 years (evaluated through a 5000-hour accelerated weathering test) ■ Offers 8 types of light colors in addition to white ■ Improved stain resistance and meets the needs for deep colors through the use of a topcoat *For more details, please refer to the catalog available for download in PDF format.
