Silicone-Modified Alkyd Resin SA-35

Silicone-modified alkyds with 30–35% silicone content provide continuous heat resistance to approximately 200°C and intermittent resistance to 250°C, compared to 80–100°C for unmodified alkyd. The silicone backbone resists thermal degradation while the alkyd component provides solubility, pigment compatibility, and film flexibility. For >250°C applications, a higher silicone content (>50%) or pure silicone resin is required.
