Effective demolding is a critical step in concrete production, directly impacting both the quality of the final product and the efficiency of the manufacturing process. At NINGBO INNO PHARMCHEM CO.,LTD., we understand that even the best high-performance concrete mold release oil requires correct application to yield optimal results. Our AS-986-8, an advanced oil-based mold release agent for precast concrete, is designed for superior performance, but following best practices for its use is key to unlocking its full potential.

The primary function of a release agent is to create a non-stick layer between the mold and the concrete. For our AS-986-8, this involves applying a thin, uniform film. Start by ensuring the mold surface is clean, dry, and free from any residual concrete, dust, or contaminants. Any debris left on the mold can interfere with the release agent's ability to form an even coating, potentially leading to adhesion issues or surface defects. A clean mold is the first step towards achieving that desired easy demolding release agent for concrete effect.

When applying AS-986-8, a spray application is generally recommended for even coverage. The dilution ratio is crucial: typically, mix AS-986-8 with clean water in a 1:13 to 1:15 ratio, ensuring it is thoroughly stirred until fully emulsified. Apply the mixture evenly onto the mold surface using a spray gun, maintaining a consistent distance of approximately 50-60 cm. It's vital to avoid overspraying, pooling, or repeated applications in the same spot, as this can create a barrier layer that might affect the concrete's adhesion to subsequent treatments or lead to surface imperfections. The goal is a light, consistent coating.

Allow the applied release agent to dry slightly before pouring the concrete. This drying time allows the emulsified agents to form the necessary protective film. The exact duration can vary based on ambient conditions, but a slight surface dryness indicates readiness. Always conduct a test on a small area of the mold before full-scale production to fine-tune application techniques and ensure desired results. This practice is part of providing a cost-effective concrete mold release solution by preventing waste and rework.

The AS-986-8 is formulated for water and heat resistance, making it durable even in challenging environmental conditions. One of the significant advantages of using a quality oil-based mold release agent for precast concrete is the extended reusability of molds. When applied correctly, the release agent protects the mold surface, prolonging its lifespan and reducing replacement costs. This contributes to the overall efficiency and sustainability of the precast concrete manufacturing process, reinforcing our position as a provider of high-quality, reliable construction chemicals from NINGBO INNO PHARMCHEM CO.,LTD.
