YBS-HSC Plus Paste is a high-performance anti-seize and assembly paste designed for metal-to-metal contact under extreme temperatures, heavy loads, and corrosive environments. It provides excellent anti-seizure performance, enabling easy, non-destructive dismantling even after prolonged exposure to temperatures up to 1,100°C (2,012°F).
With a stable and low coefficient of friction, it ensures consistent bolt preload while offering outstanding corrosion protection and electrical conductivity. Free from intentionally added PTFE and PFAS, it is ideal for bolted joints, turbines, turbochargers, flanged connections, and other high-temperature industrial applications requiring reliable long-term protection.
Performance characteristics
Can be used over a wide range of temperatures (-30°C/-22°F to 1,100°C/2,012°F)
Enables nondestructive dismantling, even after long use at high temperatures
High load-carrying capacity
Due to stated coefficient of friction, defined pre-stressing forces for bolted joints can be achieved
Good corrosion protection
Good electrical conductivity
