描述

🔸 Product Introduction

• This product is a professional release agent for concrete flue ducts, applicable to both machine-made and hand-crafted ducts.
• Suitable for demolding flue ducts made with cement mortar, prefabricated components with fly ash, lightweight aggregate, expanded perlite, etc.
• Applicable molds: steel molds, iron molds, wooden molds, glass fiber reinforced plastic molds, plastic molds, and rubber molds.
• Environmentally friendly and safe: non-toxic, non-corrosive, rust-proof, with no petroleum safety risks.
• After demolding, the concrete surface appears smooth, clean, and uniform in color with minimal bubbles.
• Water dilution ratio for duct concrete demolding: 7–10 times. High cost-performance ratio.
• Specification: Net weight 20 kg/barrel.

🔸 Product Performance

• Appearance: Milky white liquid; pH: Neutral (7–8).
• Emulsion stability: Stable emulsion, recommended for immediate use.
• Demolding effect: Easy release with smooth concrete surfaces and a clean finish.
• Mold adhesion: <3.0g/㎡; Corrosion resistance: No corrosion to steel molds.
• Water resistance: Good performance against rinsing by water.

🔸 Method of Application

1. Dilution ratio: Steel molds—1:7 with water. Shake well before diluting.
2. Example (for steel/glass fiber molds): Mix 1 part of release agent with 7 parts water. Mix thoroughly. Use a sprayer to apply evenly to the mold surface. Do not over-spray. Once a thin film has formed, concrete can be poured.
3. Tip: If demolded surface shows powder or lacks gloss, adjust dilution ratio upward (e.g. 1:8) to achieve desired effect.

🔸 Attention to Construction

1. Uniform Application: For projects like water-based flue ducts, spray release agent on multiple molds at once. Start pouring concrete after completing spraying on all molds to ensure consistency.
2. Fly ash mixes: Can be demolded directly after spraying.
3. Cement mortar: Must wait until demolding agent dries before pouring.
4. Visual Check: After spraying, inspect mold surface to ensure coverage. Record inspection to verify full application and ensure smooth demolding.
