Moisture and heat resistance test for adhesives

Evaluation of adhesive strength in high temperature and high humidity environments! Chemical analysis (FT-IR, GCMS, etc.) is also available to elucidate the degradation mechanisms of materials.

We conducted a "moisture and heat resistance test for adhesives" to investigate changes in adhesive strength due to the effects of moisture and heat. The test specimens were placed in a constant temperature and humidity testing machine, and after 500 hours, they were removed to measure the tensile shear adhesive strength. It is presumed that the adhesive strength decreased due to the swelling of the adhesive in a high-temperature and high-humidity environment. We can conduct various environmental tests and strength tests on a variety of materials, not limited to adhesives. Additionally, we also provide chemical analysis to clarify degradation mechanisms. [Test Results] ■ The adhesive strength (breaking stress) of samples placed in a humid heat environment for 500 hours significantly decreased. ■ From the stress-strain curve of the tensile test, a decrease in the modulus of elasticity for both adhesives A and B was confirmed. ■ It is presumed that the adhesive strength decreased due to the swelling of the adhesive in a high-temperature and high-humidity environment. *For more details, please download the PDF or feel free to contact us.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and responds to various situations from passing to stationary vehicles. It can be used for the opening and closing of input doors at waste treatment plants, as well as for gates that vehicles pass through and outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 ■ Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism ■ Protection rating IP68 reduces the risk of water ingress ■ Ten times the load capacity compared to conventional embedded park sensors (based on our comparison) ■ Can distinguish between vehicles even when they pass continuously ■ Can be installed on rebar and steel plates *For more details, please refer to the PDF document or feel free to contact us.

We will be exhibiting at the 2025 Autumn Conference of the Japan Society of Fisheries Science, a public interest incorporated association. We will showcase examples such as fishery environment monitoring, distribution surveys of sea urchins, which are one of the causes of coastal degradation, and the underwater time-lapse cameras that are active in monitoring damage in aquaculture sites. Additionally, we will introduce kits for collecting dead fish in aquaculture sites and sediment sampling kits that can be attached to underwater drones. Please feel free to ask the booth staff about new graduate recruitment and mid-career hiring for the 2027 fiscal year. We look forward to seeing you there. Date: September 24 (Wednesday) to September 27 (Saturday), 2025 Location: Hiroshima University, Higashi-Hiroshima Campus, Faculty of Biological Production (Higashi-Hiroshima City, Hiroshima Prefecture)

Are you managing daily attendance with time cards or handwritten work schedules? (Employees) If only we could make daily clock-ins and paid leave requests easier... (Managers) If only we could make confirming and collecting missed clock-ins and visualizing work hours easier... (General Affairs Staff) If only we could make waiting for documents from managers, calculating overtime, and payroll easier... We especially encourage customers with a lot of manual work to consider this: Introducing the attendance system "KING OF TIME," which can be started for just 300 yen per person per month. By fully utilizing our unique support system, implementing it while handling regular operations is not a dream!

Since its release in 2008, the LED lighting for image processing, 'Kou Shop', which boasts a rich lineup and high quality at low prices, has been well-received by many customers. We are excited to introduce a new product, the 'T-E Series', consisting of 8 different models. The main features are five: 1. Brightness has improved by approximately 1.6 times! (for white light) 2. Power consumption has been significantly reduced to about half! (for white light) 3. Operating temperature range has expanded to 0–60°C (compared to 0–40°C for previous models) 4. Same shape as previous models, allowing for direct replacement with your current power supply 5. Prices remain unchanged (note: some colors may have price changes) By reducing power consumption, not only does this lower running costs, but it also allows for the use of inexpensive low-output power supplies, contributing to overall cost reduction of the equipment. Furthermore, with the expanded operating temperature range, you can use it confidently even in high-temperature and harsh environments. The T-E Series, with significantly improved performance, has evolved the previous concept further and is now a product that can meet diverse needs. We invite you to take this opportunity to experience the capabilities of the T-E Series. We are also offering free demo units for loan, so please feel free to contact us.
