Series

Boron-modified

Very high temperature, self-healing

Cure
Heat; ramp to 800 °C for conversion

Boron in the network raises the temperature a film survives and lets it heal its own cracks on reheating. Two grades differ in boron content and viscosity. Intended for ceramic matrices, graphite and carbon parts that see oxidation and thermal cycling, not for decorative coating.

How to choose inside this series

The low-viscosity grade penetrates a porous part; the thick grade builds a layer on a surface. Both want a slow ramp rather than a hot oven.
