Question 1

Why choose a silicone-free leveling agent like PLE-100 over silicone-based alternatives?

Accepted Answer

Silicone-based leveling agents can migrate to the coating surface and cause intercoat adhesion failures in multi-layer systems. PLE-100's EO/PO polyether backbone delivers equivalent dynamic surface tension reduction and flow improvement while remaining compatible with recoat and overprint operations, making it preferred for furniture, industrial, and automotive refinish applications where topcoat adhesion is critical.

Question 2

At what addition level should PLE-100 be used in a waterborne acrylic formulation?

Accepted Answer

Typical effective dosage is 0.1–0.3% on total formulation weight for waterborne acrylics. For UV-cure systems with higher surface tension, up to 0.5% may be needed. PLE-100 is 100% active and water-miscible; it is best added to the letdown stage with slow stirring. Overdosing above 0.5% can reduce surface tension excessively, promoting foam stabilization rather than leveling.

Question 3

Does PLE-100 affect substrate wetting in addition to leveling?

Accepted Answer

Yes. By lowering dynamic surface tension, PLE-100 accelerates substrate wetting and reduces crawling defects on low-energy surfaces such as plastics and aged metals. However, it is not a primary wetting agent; for aggressive substrates, combining PLE-100 at 0.2% with a dedicated wetting dispersant at 0.1–0.2% gives the best balance of wetting speed and final film leveling.
