The Invisible Battle of Silicone Polyether Defoamers: How Chemi Tech Solves Foam Challenges

At a mid-sized coatings factory in East China, plant manager Zhang stared at the foam overflowing from the reactor. The urgent order was already delayed—foam reduced filling efficiency by 30%, and micro-craters on finished surfaces triggered client complaints.

“We tried defoamers that either failed under heat or ruined coating gloss,” Zhang said. The turnaround came with Chemi Tech 2600, a silicone-polyether hybrid defoamer.

Dual-Action Innovation

Chemi Tech engineers discovered conventional defoamers degrade in high-shear environments. Chemi-Tech 2600 combines silicone and polyether chains to deliver:

“15% less dosage, but 20% faster line speed,” Zhang noted. A Zhejiang textile auxiliary plant also used it to eliminate dyeing vat foam-induced color deviations.

Why Chemi Tech?

“A defoamer isn’t just an additive—it’s the silent guardian of your production line,” Chemi Tech’s R&D head concluded.
