Product Description

Product Description

AS-865 is a professional release agent formulated for precast concrete applications, widely used in prefabricated components for buildings, railways, and highways, such as beams, columns, slabs, caps, guardrails, high-speed rails, and bridge tunnels.
•    Suitable for steel, wood, and aluminum molds.
•    Environmentally friendly: non-toxic, odorless, corrosion-resistant, rust-proof, and free from petroleum safety hazards.
•    After demolding, concrete surfaces appear evenly colored, smooth, and low in bubbles.
•    High dilution ratio: can be diluted 10–15 times with water, offering excellent cost performance.
•    Packaging: 20 kg per drum.

Key Features

•    Appearance: Milky white liquid
•    PH value: Neutral (7–8)
•    Storage stability: Stable, ready-to-use on site
•    Demolding effect: Easy release, smooth surface
•    Residue on concrete: ≤3.0g/m², no damage to steel molds
•    Water resistance: Good resistance to rainwater washing

Application&Usage Instructions

Application

Suitable for steel, wood, and aluminum molds.

Usage Intructions

1.    Dilution Ratios:
o    Aluminum mold: 1:10
o    Steel mold: 1:15
o    Wooden mold: 1:12
Stir well before mixing with water.
2.    Example (Steel mold):
Mix 1 part release agent with 15 parts water. Pour into a sprayer and stir evenly. Spray onto mold surface, ensuring even coverage. After spraying and a short wait (10–30 minutes), proceed with concrete pouring. If surface powdering occurs, increase dilution ratio to 1:16 for better results.

Dilution Ratios	1:10	1:15	1:12

Construction Tips

1.    Always follow recommended dilution ratios; do not spray on wet molds.
2.    Spray only after the release agent is thoroughly applied and mold surface is dry.
Note: After spraying, mold surfaces may appear untreated. Do not wipe. The release agent creates an invisible film. If unsure, perform a spot spray test. Capture video to check smoothness and shine—adjust as needed for optimal results.
