Purpose
Prevents oxidation during processes such as annealing, suppressing scale formation and discoloration during heating.
It also protects various ultra-high-temperature areas with a heat-resistant film, reducing material deterioration and wear.
Features
| Forms a Water-Resistant Coating at Room Temperature | Forms a water-insoluble coating after drying at room temperature. |
|---|---|
| Suitable for Ultra-High-Temperature Applications | Delivers stable heat resistance even under ultra-high-temperature conditions. |
| Excellent Adhesion Even on Smooth Surfaces | Adheres well even to smooth machined surfaces. |
| Low VOC for Reduced Environmental Impact | Its composition is nearly equivalent to naturally occurring substances, and with organic solvents at less than 1%, it has a low environmental impact. |
