•  Dilutable 8--15× with water; high value.

Product Performance

•    Appearance: Light golden- yellow liquid
•    pH: Neutral 7
•    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

Applications 
Small precast items—kerbs, trench covers, slope blocks, high-speed rail fences, reliefs, planters, hex blocks, Roman columns, retaining walls, etc.

Specification

Physical property:	Water based	pH:	7
Effecitive content:	55%	Dilution:	1:8-15
Suitable molds:	Plastic mold	Advantages:	High defoaming, excellent smooth surface
Applications:	Small precast items—kerbs, trench covers, slope blocks, high-speed rail fences, reliefs, planters, hex blocks, Roman columns, retaining walls, etc.

Usage Intructions

Step 1: Clean the mold thoroughly.

Step 2: Mix AS-986-6 at 1 : 8-  12 with tap water (1 dipper agent to 8-  12 dippers water). The golden concentrate turns milky white once diluted; stir well.

Step 3: Fill the diluted mix into a high-pressure spray gun. Set the nozzle to the finest, widest mist  (a slightly tighter spray for irregular molds) and use maximum pressure.

ATTENTION TO  CONSTRUCTION

1.  Hold the spray gun 50-  60 cm from the mold and sweep quickly in a thin, even coat—use only one-third the volume of oil or diesel. It will look and feel like nothing is there within 2-  3 minutes.  DO NOT re-spray; the invisible film is the release barrier.

2.  After the release agent is fully dry, pour the concrete and strip as usual.

Tip: Run a few test cycles on the same mold to fine-tune the spray volume before full production

FAQ

Common Issues When Purchasing Release Agents

Q1: What types of mold release agents are available?
  -  We offer water-based, oil-based and bio-based products. Water-based is eco-friendly, odorless, non-flammable and VOC-free, ideal for precast concrete and precision molds. Oil-based is cost-effective with strong release performance, for large rough molds like spun piles. Bio-based is biodegradable, complying with EU and North American environmental rules. Exporters to these regions should choose water-based or bio-based types.
Q2: Will they affect concrete surfaces or later finishes?
  -  Our quality water-based agents cause no fisheyes or delamination. For exposed concrete, our special colorless product is recommended with on-site photos for reference.
Q3: How long do they work? Resist high temperature and rain?
  -  AS-865 resists rain wash, effective up to 7 days, suitable for large steel molds and delayed construction. It stays stable in high heat and heavy rain, perfect for Middle East and Southeast Asian projects.
Q4: For steel-mold precast concrete?
  -  Our water-based agent forms a uniform nano-film, making precast surfaces smooth without re-grinding and won't block mold air vents.
Q5: For concrete piles & manhole covers (low-cost)?
  -  Oil-based or high-concentration agents (dilutable 1:15–1:20) lower per-cubic-meter cost while ensuring easy demolding.
Q6: For wooden formwork?
  -  Wood absorbs easily, use high-viscosity oil-based or wood-specific agents; note mold material when ordering.
Q7: Dangerous goods? LCL shippable?
   - Both types are non-dangerous, no diesel/engine oil. Water-based ships LCL/FCL directly; oil-based is non-flammable (flash point >100°C) with freight reports. Cheap diesel-mixed products risk customs detention.
Q8: MSDS & third-party reports?
   - Yes: bilingual MSDS, EU RoHS/REACH reports and SGS physicochemical test reports.
Q9: Unsatisfactory performance?
   - 100% quality guarantee: technical support first, then free replacement or full refund if verified unqualified.
Q10: Why AS-865 ($2.96/kg) vs $1/kg products?
   - Cheap ones have low solid content , need low dilution as 1:1 or direct use, higher real cost and easy mold adhesion. AS-865 is highly concentrated dilution can be 1:15 ~20, covers more area with lower overall cost. Calculate cost per square meter instead of per kg.
