When sealants are applied in various high-temperature environments, heat resistance becomes the core indicator for evaluating their quality. Yoshida Chemical's hydrogenated rosin AT22 demonstrates exceptional performance, undergoing rigorous testing at 180°C for 8 hours with a color change of less than 1. This indicates it maintains high chemical stability under prolonged high temperatures, effectively preventing sealant degradation, aging, or deterioration due to heat exposure. Consequently, it ensures the sealant's sealing performance remains durable and reliable. Whether used in electronic device encapsulation or industrial pipeline joint sealing, sealants incorporating Yoshida Chemical's hydrogenated rosin AT22 leverage its outstanding heat resistance to provide a robust protective barrier for equipment and engineering applications. This significantly extends equipment lifespan and operational stability, enabling your products to function efficiently and safely even in high-temperature environments.
