Defoamers for Coatings, Adhesives & Sealants
With global expertise in foam control, PMC OUVRIE offers advanced solutions for coatings, adhesives, and sealants, available in English, French, and Spanish. Our EROL™ and DELFOAM™ product lines are specifically engineered to address foaming-related issues in the production of various surface coatings, including stains, paints, and coatings. These innovative defoamers for coatings are essential for maintaining the quality and efficiency of your production processes.
The right defoamer depends on both the formulation and the stage at which air enters the process.
Foam Control in Coatings
Foam and entrained air can contribute to several coating defects:
- Pinholes and craters: Bubbles that reach the surface and burst during drying can leave small openings or depressions in the film.
- Reduced gloss: Air trapped in a coating can affect how light reflects from the finished surface.
- Fish-eyes: An incompatible defoamer can create localized surface defects, making formulation compatibility an important part of product selection.
Foam control helps manufacturers manage these issues while maintaining a consistent coating process. We offer two defoamers for paint and coating formulations. The following table compares applications, chemistry, and operating temperatures to help identify which product may suit your process.
| Product | Chemistry | Applications and Selection Considerations | Operating temperature |
|---|---|---|---|
| EROL™ FG 5 | Advanced surfactant blend | Water-based paints and architectural coatings where compatibility and a low risk of surface defects are priorities | 15–30°C |
| EROL™ AMP 19 | Specialized wax dispersion | Matte-to-semi-gloss industrial coatings, stains, and protective wood finishes | 15–30°C |
Foam Control in Adhesives and Glues
Air can enter an adhesive formulation during mixing and application, creating several processing challenges:
- Mechanical agitation: Tank mixing and high-speed application equipment can introduce air into an adhesive formulation.
- Uneven substrate wetting: Air pockets can interrupt contact between the adhesive and the substrate, potentially affecting bond consistency.
- Uneven dispensing: In spray or extrusion systems, entrained air can contribute to spitting or an inconsistent application pattern.
We offer DELFOAM™ B 27 for adhesives and glues. This table summarizes applications, performance characteristics, and operating temperature.
| Product | Chemistry | Applications | Performance characteristics | Operating temperature |
|---|---|---|---|---|
| DELFOAM™ B 27 | High-stability wax dispersion | Water-based glues, paper packaging adhesives, and industrial sealers | Designed to maintain foam control under high-shear processing while limiting separation and oil spotting | 15–30°C |
Foam Control in Sealants
Air trapped in a sealant can affect both production and the appearance of the applied material:
- Inconsistent dispensing: Entrained air can interrupt the flow of sealant during application.
- Surface bubbles: Air released after application can leave visible bubbles or an uneven finish.
- Incomplete contact: Air pockets at the joint surface can reduce the area of contact between the sealant and the substrate.
Defoaming and deaeration can help manufacturers manage air during production. The table below summarizes DELFOAM™ B 27’s applications, performance characteristics, and operating temperature for sealant formulations.
| Product | Chemistry | Applications | Performance characteristics | Operating temperature |
|---|---|---|---|---|
| DELFOAM™ B 27 | Wax dispersion | Liquid sealants, caulks, and industrial sealers | Helps control air introduced during mixing and filling, supporting consistent dispensing and surface appearance | 15–30°C |
Essential Properties
Our defoamers possess both defoaming and deaeration properties, ensuring smooth and efficient production processes by effectively managing foam generation. By incorporating our defoamers, manufacturers can enhance the stability of their formulations, leading to improved application, reduced waste, and consistent product quality.
Defoaming addresses visible foam at the surface, while deaeration helps release air trapped within the formulation. This distinction is useful in coatings, adhesives, and sealants, where entrained air may remain even after surface foam has subsided.
Additionally, our products are designed to be compatible with a wide range of raw materials used in defoamers for coatings, adhesives, and sealants, making them versatile solutions for various production environments.
