Latex Paints

Wood & Furniture Coatings

Architectural Coatings

Industrial Coatings

Overprint Varnishes

Other waterborne coating systems based on various latex and resin systems.

Application Guide

Recommended Dosage

The recommended dosage is generally 0.1–0.5% based on total formulation weight.

The optimum dosage should be determined through application testing according to the specific formulation and processing conditions.

Incorporation Method

NV-DF 9044 can be added directly during the manufacturing process or pre-dispersed in the formulation before use.

Paint Manufacturing

For coating production, it is recommended to add:

50% of the total defoamer dosage before grinding

The remaining 50% after grinding during the let-down stage

This addition method can provide effective foam control throughout the manufacturing process.

Handling & Precautions

Stir well before each application to ensure absolute product homogeneity after long periods of storage.

Avoid prolonged skin and eye contact.

Storage：

Temperature Range: Keep stored in original sealed containers between 5℃ and 35℃. Strictly protect from freezing (0℃) and extreme hot environments.

Shelf Life: Minimum shelf life is 12 months from the date of chemical packaging under tightly closed conditions.
