Notice of Participation in the 23rd International Auto Aftermarket EXPO 2026 (IAAE 2026)

Easy-to-understand explanation of the causes of rust and types of rust prevention treatments [Free materials available].

Rust on vehicles such as commercial and private cars is a concern. "Salt Damage Guard" is a hybrid paint that combines adhesion, impact resistance, and rust prevention effects. It clears a rigorous saltwater spray test of 1,000 hours with additives like resins and aggregates that have excellent rust prevention capabilities. By combining it with acrylic resin that excels in chip resistance, it achieves strong rubber elasticity that can withstand impacts from small stones while driving. We provide clear explanations of the causes of rust on vehicles and methods to protect against it.

We also have a salt damage guard pouch gun with an adapter! After use, it can be rolled up and disposed of, reducing waste.

This product is a pouch pack of water-based salt damage guard that complies with organic regulations and PRTR clearance. When applied with the dedicated "Salt Damage Guard Pouch Gun," it is possible to draw up the paint until the very end. This clarifies how much paint is used for one vehicle, contributing to cost management. Depending on the shape of the lift, it may be difficult to reach certain areas with a 1L can, but with the smaller volume of the container and the material being less likely to scratch the vehicle, it allows for closer application to the target object. 【Features】 ■ Reduction of waste volume and weight ■ Reduction of material loss ■ Visible usage amount ■ Application possible in hard-to-reach areas *For more details, please refer to the PDF document or feel free to contact us.

Rust prevention treatment can be done in a short construction time! This product can treat approximately one regular car with just one bottle of this easy-to-use rust inhibitor.

"Salt Damage Guard Rust Block 365" is a rust preventive agent that excels in water displacement and protects the lower body of vehicles from moisture containing salt, which causes rust. With its powerful rust prevention effect, it prevents rust caused by de-icing agents (such as calcium chloride) and sea breeze. It penetrates gaps and provides rust prevention to the details of metal parts, forming a non-drying transparent oil-type film. It can be used on various metal parts, radiators, and mufflers (from the catalytic converter to the rear section). 【Features】 ■ Passes saltwater spray test for over 120 hours ■ One bottle can treat approximately one regular vehicle ■ Not subject to specific regulations or organic regulations; oil-based type ■ Minimal impact on rubber, resin, and painted surfaces (automobile body) ■ No complicated masking required *For more details, please refer to the PDF document or feel free to contact us.

PRTR and organic regulations do not apply! Introduction of a rust treatment agent suitable for creating a substrate for salt damage protection construction.

"Salt Damage Guard Rust Converter" is a rust treatment agent suitable for surface preparation of rusted areas and for pre-treatment before applying salt damage guard on aging vehicles. It reacts only with rust to form chemically stable black rust. Construction work can be carried out one hour after application. You can view the construction manual explaining the application range, materials, and application methods by downloading the PDF below. We encourage you to read it. 【Features】 ■ Not subject to PRTR ■ Not subject to organic regulations ■ Reacts only with rust to form chemically stable black rust ■ Forms a suitable base for salt damage guard application ■ Construction work can be carried out one hour after application *For more details, please refer to the PDF document or feel free to contact us.

Heat pipes are passive heat transfer devices that utilize latent heat of vaporization in a two-phase system and do not require driving energy. Heat pipes have very high thermal conductance, with their equivalent thermal conductivity being several hundred times higher than that of a copper rod of the same size. The primary application of heat pipes is in the cooling of computers and electronic products. Recently, AI servers and data centers have gained attention; for example, nVidia's GPUs can reach heat generation of up to 1 kW, employing water-cooled cold plates and 3D vapor chambers. Air cooling is limited to 800 W, while nVidia's Ruben GPU can reach 2 kW, utilizing water-cooled microchannel cold plates, among others. In response to further increases in heat generation, vapor chamber composite cold plates, two-phase pump loop cooling, and impingement cooling have been developed. Additionally, recent cooling cases for batteries, motors, and IGBTs in electric vehicles will be discussed.

In the past, thermal design primarily focused on complex heat transfer through convection and radiation to the atmosphere. However, with the increase in surface-mounted components and power density, the heat dissipation pathways are gradually shifting to thermal conduction through substrates and enclosures. One of the key heat dissipation devices to promote heat transfer in limited spaces is TIM (Thermal Interface Material). A wide variety of TIMs have been developed in the market, and in recent years, key areas where TIMs are widely used include AI data centers and automotive equipment centered around electric vehicles (EVs). In this course, we will first explain the overview of heat dissipation design in AI data centers and automotive equipment, and in the latter half, we will provide a detailed explanation of the thermal and mechanical properties of TIMs in these two fields, as well as important considerations when selecting TIMs.
