Master Air is a high-performance air release agent used primarily in concrete and construction applications. It facilitates the release of entrapped air bubbles from fresh concrete mixtures, improving workability, surface finish, and durability. This additive enhances the homogeneity of concrete by reducing air voids that can weaken the structure. Master Air is suitable for use in ready-mix concrete, precast elements, and other cementitious materials, contributing to improved mechanical properties and longevity of the final product.

Master Air

Primary Uses

Concrete Industry

Acts as an air release agent to eliminate entrapped air bubbles during mixing and pouring.
Improves surface finish by reducing pinholes and surface defects.
Enhances the durability and strength of hardened concrete by minimizing voids.

Precast Concrete Manufacturing

Used to ensure smooth and defect-free surfaces on precast concrete products.

Secondary Uses

Mortar and Cementitious Mixes

Applied in mortar mixes to improve workability and surface quality.

Other Construction Materials

Can be used in specialized formulations where air entrapment negatively affects product quality.
