Technology for improving wear resistance, damage resistance, and rust prevention of construction machinery parts.
By applying resin lining to the surface, the deterioration areas caused by the harsh operating environment of construction machinery are improved in terms of wear resistance, breakage resistance, rust prevention, waterproofing, fire resistance, and chemical resistance!
In an environment where various deterioration factors such as severe wear on construction machinery bodies, buckets, and shovels, cracks due to impacts, corrosion from chemicals and salt, and thermal effects are compounded, applying a polyurethane resin lining to the surface continues to protect the base part for an extended period. According to JIS standards, the paint wear test shows a film loss of 3mg after testing, demonstrating significantly superior wear resistance compared to other lining materials, and its high weather resistance ensures stable strength outdoors for a long time. By applying polyurethane coating particularly to the severely deteriorated parts of bulldozer buckets, shovels, conveyor systems, and agricultural tools such as tilling blades and cutting blades, an extension of their deterioration lifespan can be expected. In the case of snowplow shovels, it has shown significant effectiveness in wear resistance and resistance to calcium chloride, and in high-grade materials with excellent chemical resistance, it has long-term resistance to 50% sulfuric acid, protecting the substrate from corrosive factors (acids, alkalis, etc.).

basic information
The next-generation lining material "Polyurea" is a resin compound formed by the chemical reaction between isocyanates and polyamines. It is a resin lining material that possesses "strength" comparable to concrete and "flexibility" that allows it to follow the shape of the substrate without cracking. It can be applied as a surface protective material for various materials such as metal, wood, urethane, concrete, and stone. It excels in waterproofing, chemical resistance, heat resistance, and weather resistance, protecting the substrate from a wide range of deterioration factors. It also has high rust prevention performance and UV resistance. There are heated curing types, room temperature curing types, and hand-applied types, which cure in a matter of seconds to minutes. 【General Characteristics of Polyurea】 ■ Follows cracks in the substrate and maintains waterproof performance ■ Depending on the grade, elongation rates can exceed 400% ■ Protects the substrate for long periods even in environments where various deterioration factors are compounded ■ Solvent-free with low environmental impact ■ 100% solid content with zero VOC emissions ■ High elasticity and flexibility ■ High solvent, acid, and corrosion resistance ■ Abrasion resistance

Company information
Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
