Name: Wacker SE 39 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Wacker SE 39 Defoamer

Highly effective silicone-based defoamer with rapid knock-down and lasting foam suppression.
Excellent compatibility in aqueous systems, including those containing surfactants, electrolytes, or high solids content.
Thermally stable up to 120 °C, maintaining performance across a broad processing temperature range.
Low dosage requirement—typically effective at 0.01–0.1 wt%—minimizing formulation impact and cost-in-use.
Non-yellowing and non-staining, suitable for applications where optical clarity or color stability is critical.
