KR-251 is a rapid cure, medium hardness silicone resin. It forms a thin, hard coating when cured on surfaces, and has low compatibility with organic resins. KR-251 also absorbs very little moisture and retain high volume resistivity over from 25-200°C, which makes it useful in protecting electronic components.
