Description

Product Introduction

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 8–15 times with water, offering excellent cost performance.
• Packaging: 20 kg per drum.

Product Performance

• 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

Method of Application

1. Dilution Ratios:
   • Aluminum mold: 1:10
   • Steel mold: 1:15
   • 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.

Attention to Construction

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.
