High-Temperature Protection
DY-26
High-Temperature Transition Sealer Primer
Penetrating sealer and transition primer for porous metallic and refractory substrates.
What problem does it solve?
Protection matched to the operating condition.
An inorganic nano-binder coating with boron nitride, rare-earth oxides and nano-silica used to seal pores and provide a transition layer to subsequent high-temperature coatings.

Application instructions
Construction sequence from the product source
Surface Preparation
Metal to Sa 2.5 or St 3 with 20-30 μm roughness; non-metal substrate dry, sound and clean.
Application Environment
Normally ≥10°C; substrate ≥3°C above dew point; relative humidity ≤85%.
Mixing
For two-component form, mix as instructed on the product label, mature 10 minutes, then filter through 60-80 mesh.
Application Tools
Brush, airless spray or air-assisted spray.
Recoat Time
Apply the next coating after the sealer is hard dry.
Precautions
Begin coating promptly after substrate preparation, generally within 8 hours.
