Defoamers for Mortar and Gypsum Systems: Improving Density, Surface Quality, and Performance
In dry-mix mortar, gypsum products, and self-leveling materials, entrapped air is a common issue during mixing and application. Excessive foam can lead to surface pinholes, reduced material density, and lower mechanical strength, ultimately affecting both appearance and durability.
Keiway Defoamers are specifically designed to control and eliminate unwanted air bubbles in cementitious and gypsum-based systems. By effectively breaking foam and preventing air entrapment, they help achieve smoother surfaces, higher strength, and more reliable performance in modern construction materials.
Backed by years of experience in construction chemical additives, Keiway offers dependable defoaming solutions for both dry-mix and wet-mix formulations.
What Is a Defoamer?
A defoamer, also known as an anti-foaming agent, is a functional additive used to reduce or eliminate foam generated during mixing and processing.
In mortar and gypsum systems, foam is often introduced by mechanical agitation, surfactants, or polymer additives.
Keiway Defoamers work by rapidly destabilizing air bubbles within the mixture, allowing trapped air to escape. This results in more uniform mixing, improved flow, and cleaner surface finishes.
Key Benefits of Keiway Defoamer
Rapid Foam Breakdown
Effectively eliminates both surface and internal air bubbles, improving flowability and overall material consistency.
Durable Anti-Foaming Performance
Maintains long-lasting foam control during mixing, pumping, and application, preventing re-foaming throughout the process.
Improved Density and Mechanical Strength
By reducing air content, materials become denser and stronger, with fewer voids and surface defects.
Broad Compatibility
Compatible with polymers, cellulose ethers, superplasticizers, stabilizers, and other commonly used construction additives.
Environmentally Responsible
Formulated with low-VOC and non-toxic components, suitable for sustainable and environmentally compliant building materials.
Typical Applications
Keiway Defoamers are widely used in:
-
Dry-mix mortar and tile adhesive
-
Cement-based and gypsum self-leveling compounds
