JTB Precast Mold Release Agent is a ready-to-use, stable, and non-toxic water-based emulsion. It exhibits strong adhesion to formwork, good resistance to washout, and a powerful hydrophobic effect, effectively reducing or eliminating surface defects on precast and prestressed concrete elements.
• High surface flatness & smoothness for demolded products
• Easy demolding & cleaning
• High stability, no delamination
• Erosion & weather resistant
• Water-based, eco-friendly & non-corrosive
• For demolding steel formwork, concrete molds, cast-in-place concrete products, pipes, pipe piles, bridge precast components, and prefabricated/modular building elements
• Surface preparation: Before spraying the Precast Mold Release Agent, if the mold has rust or oil stains, first grind and remove the rust, then clean it thoroughly and let it dry.
• Mixing and stirring: For initial use, mix with clean tap water at a ratio of 1:5 (i.e., 1 kilogram of JTB Precast Mold Release Agent +5 kilograms of water). Stir thoroughly with a stirrer for 5 minutes to ensure that the mold release agent is completely dissolved in the water.
• Construction: Use the spraying method to apply a mist and uniform spray to the surface of the mold. Each area must be sprayed thoroughly and moistened.
• Application method: Evenly apply a moist pure cotton yarn (pure cotton yarn without hair removal or pure cotton yarn towel) soaked in Precast Mold Release Agent to the surface of the mold to form a thin and even isolation oil film.
•Reference usage: 15 to 20 square meters per kilogram. One application can be demolded 3 to 5 times.
If the JTB Precast Mold Release Agent is used for the first time and there is dust on the mold surface, when preparing the release liquid, a small amount of diesel can be added for stirring.
For the concave and convex parts of the mold, please pay attention to spraying them carefully and thoroughly to ensure they are fully moistened. After spraying or wiping, there should be no accumulated liquid on the surface of the mold, especially in the depressions. If there is accumulated liquid or a large number of liquid droplets, please apply it evenly with pure cotton yarn.
In winter, please dilute the Precast Mold Release Agent at a limited ratio of 1:4 with water to increase its concentration and ensure the usage effect.
Do not mix with products from other manufacturers. Use strictly in accordance with the prescribed ratio.
Packaging Specifications: Drums, 20 kg or 50 kg per drum.
