Concrete Release Agent

Concrete Release Agent

Concrete release agents are primarily suitable for a wide range of concrete products such as bridges, tunnels, highways, high-speed rails, subways, building construction, precast components, double T-slabs, partition panels, flues, composite slabs, staircases, subway segments, inspection wells, cement pipes, wind turbine towers, curb stones, trench covers, hexagonal blocks, precast U-shaped channels, leak slabs, flower pots, imitation wood piles, and more. We provide customized solutions, possess extensive sales experience and strong communication skills, and are highly trusted by our clients.

A concrete release agent is a substance applied to construction formwork before concrete pouring to prevent the formwork from sticking to the concrete surface after pouring, making demolding difficult, or affecting the smoothness of the concrete surface. Its main function is to form a film between the formwork and the concrete surface, isolating the two, hence it is also known as a parting agent.

Main Uses of Concrete Release Agents:

Widely used in various steel formworks, wooden formworks, bamboo plywood, plastic boards, and concrete tabletops in concrete engineering construction.

Concrete release agents are also water-soluble, meaning their internal components can fully dissolve in water. Emulsions of compounds such as methyl silicone oil are commonly used in industry. These emulsions are water-soluble and offer high heat resistance, easy cleaning, good corrosion resistance, fire resistance, minimal environmental pollution, and relatively safe transportation and storage.

Due to their high water content, water-based concrete release agents differ in many aspects from traditional oil-based or solvent-based release agents. The demolding effect of a concrete release agent depends on a film only a few micrometers thick deposited on the mold cavity surface after spraying. Therefore, there are higher requirements for ingredient selection and application techniques. However, their advantages are also evident: they facilitate automated operations, provide excellent cooling effects, prevent scaling, improve the surface quality of castings, reduce internal porosity, ensure safe usage, promote clean production, and minimize environmental pollution.

Concrete release agents combine the features of similar domestic and international products. They are viscous emulsions synthesized through advanced molecular synthesis technology using high-molecular polymers and various chemically active substances, offering fast film formation and easy stripping. Concrete release agents are widely suitable for large cement bridge factories, highways, bridges, rails, subway segments, cement pipe plants, high-rise building concrete aluminum formwork construction, steel formwork construction, wooden formwork, bamboo plywood, resin molds, and ground molds.
Performance Characteristics
Concrete release agents form films quickly and facilitate easy demolding; they significantly reduce bubbles at the concrete interface, resulting in a smooth surface with no residue; they are waterproof, rust-proof, and greatly extend the service life of formwork and molds; they are non-toxic, odorless, non-flammable, and easy to store; they can be used directly after dilution with water, are cost-effective, and convenient to use.

Characteristics of Concrete Release Agents
1. An environmentally friendly product made from water-based polymer composite concentrate through unique formulation and grinding processes.
2. Excellent isolation performance for easy demolding.
3. Water-soluble, rust-proof, fast film-forming, protects formwork, and extends its service life.
4. Leaves concrete surfaces clean, smooth, and uncontaminated; environmentally friendly, odorless, non-toxic, non-flammable, and easy to store.
5. Customized product services available based on client on-site construction requirements.

Precautions for Using Concrete Release Agents
1. Dilute with water (dilution ratio 3-10 times as appropriate) and mix evenly. The dilution ratio can be adjusted based on on-site needs. Use the diluted mixture as soon as possible.
2. Apply using a spray gun or roller brush. Allow the applied release agent to dry completely before pouring concrete.
3. Clean the formwork or mold surface thoroughly before application.
4. Store at room temperature, protect from freezing and direct sunlight. After opening, ensure the container is sealed and stored properly.
5. Avoid construction during rain. If the applied agent is washed away by rain, reapply before proceeding.
6. Packaging specification: 50KG drum.
