We will be exhibiting at INCHEM TOKYO 2025. What is the water-repellent technology WR-Tech? It is ROCKWOOL Group's unique advanced water-repellent technology that adds a water-repellent agent to stone wool (insulation material) in the early stages of the manufacturing process (with a durability of up to 250°C), allowing it to repel water. This technology has already been proven in Europe and the United States, and we have also published practical test results. We will introduce the industrial insulation material "ProRox series" that utilizes this technology. We look forward to seeing you at booth "6-G02." Overview of WR-Tech (water-repellent technology) 1: Minimum water absorption rate 2: Quick drying 3: Water-repellent performance with a durability of up to 250°C ◎ Low leaching of water-soluble chloride ions ◎ No silicone oil used ◎ Flexible and strong INCHEM TOKYO 2025 Date: September 17-19 Location: Tokyo Big Sight Exhibition booth number: 6-G02 Exhibitor Seminar Date: September 18 (Day 2) Time: 10:30 - 11:20 Venue: Hall 1 Content: Reducing corrosion under insulation (CUI) in plant equipment piping - An approach from water-repellent insulation materials *Pre-registration required.
