Core Advantages
1. Rapidly eliminates micro-bubbles in high-viscosity formulations, reducing pinholes and bubble defects with durable foam suppression performance;
2. High temperature resistance, compatible with 2K epoxy baking and UV curing processes with low yellowing tendency;
3. Excellent performance in pigmented systems; compatibility test is required for clear coat applications;
4. Can be added during grinding or letdown stage, effectively avoiding craters and fish eyes after construction;
5. Solvent-free, zero VOC introduction, suitable for high-solid environmental-friendly formulations.
