A repair material developed for rubber bearings that has excellent elongation performance and adhesion to rubber for surface protection.
The "HB Coat" is a coating agent that protects against cracks caused by ozone degradation of the rubber surface covering of rubber bearings, as well as prevents ozone cracks. For relatively large cracks, the "HARD type" is applied, while for smaller cracks such as hairline cracks, the "SOFT type" is used. If carried during bridge inspections, it allows for on-site repairs during the inspection, eliminating the need for separate repair work later. 【Features】 ■ Developed for rubber bearings with excellent elongation properties ■ Superior adhesion to rubber ■ Two types available for different applications ■ One-component type that requires no mixing ■ Easy for anyone to use *For more details, please refer to the PDF document or feel free to contact us.
