Question 1

At what addition rate should DCC-100 be used in stoving coil coating formulations?

Accepted Answer

Typically 0.05–0.3% on total formulation weight. Add during the let-down stage under moderate agitation. Pre-diluting in a small portion of solvent or resin before addition improves dispersion uniformity.

Question 2

Is DCC-100 compatible with both polyester and PVDF-based coil coating resins?

Accepted Answer

Yes. DCC-100 is engineered for broad resin compatibility including polyester, epoxy, and PVDF systems. Its silicone chemistry remains thermally stable through stoving cycles up to 250°C without decomposing or generating surface defects.

Question 3

Can DCC-100 affect intercoat adhesion in multi-layer coil coating systems?

Accepted Answer

At recommended dosages, DCC-100 does not impair adhesion or overcoatability. Dosages above 0.5% risk silicone migration to the film surface and potential adhesion loss; pilot trials are always recommended before full-scale use.
