D2270

Polyether modified polydimethylsiloxane

Product Description

D2270 is a multifunctional wetting agent that reduces dynamic and static surface tension, improves substrate wettability, enhances spreading effect, and has oil resistance, anti-cratering, and leveling properties. It has excellent compatibility with various resins, is suitable for both water and oil systems, and also has certain defoaming capability. Additionally, it is highly efficient and can achieve ideal results at very low addition levels.

Product Features

  • Excellent wettability

  • Fast leveling speed and good leveling effect

  • Effectively prevents cratering

  • Low foam characteristic

  • Solubility: soluble in methanol, isopropanol, acetone, xylene, dichloromethane; dispersible in water.

Usage Recommendations

  • Add at 0.1% to 1% of total formula weight.

  • Can be added during grinding or mixing stage, or added after product completion.

  • For easy feeding, pre-dilute with a compatible solvent.

  • Can be diluted with water, alcohols, alkanes, aromatic solvents in any proportion.

Usage Precautions

Care must be taken when compounding with other additives; always conduct compatibility tests before production.
