Key Additives for Water-Based Industrial Coatings and Chemi Tech Defoamers

In water-based industrial coating formulations, additives play a critical role in film formation, stability, and final performance. Defoamers are among the key additives to address bubble-related issues during production and application. Chemi Tech, as a specialized defoamer supplier, offers products that effectively suppress foam formation and eliminate existing bubbles, preventing defects like pinholes or craters.  

Beyond defoamers, water-based coatings require the following additives for optimal performance:  

1. Wetting & Dispersing Agents: Enhance pigment-resin compatibility for uniform coatings;  

2. Leveling Agents: Minimize brush/roll marks for smooth surfaces;  

3. Thickeners: Adjust viscosity to suit application methods;  

4. Preservatives: Extend shelf life.  

Chemi Tech defoamers utilize unique molecular structures to rapidly penetrate foam films, ensuring efficient bubble breaking. With low dosage (typically 0.1%-0.5%), they significantly improve defoaming efficiency in spray, roller, or dip applications. Moreover, these defoamers exhibit excellent compatibility with water-based resins, avoiding adverse effects on adhesion or weather resistance.  

The industrial coating sector demands zero tolerance for defects, making professional additive suppliers vital. Chemi Tech leverages decades of expertise to deliver tailored defoaming solutions for gloss, matte, or specialty finishes.
