Polycarboxylate Superplasticizer (PCE) Powder for Gypsum, POP & Cement Casting
Looking for smoother casting with less water? Polycarboxylate Superplasticizer (PCE) is a fine powder additive used to improve flow, strength, and finish in gypsum, plaster of Paris (POP), and cement mixes. It is useful for artists, mold makers, and also used in construction.
What is PCE? PCE is a high-range water reducing agent. It helps your mix flow easily while using less water. Less water means stronger, denser, and smoother final pieces.
You add a small amount of PCE to your dry mix before adding water. It helps the mix spread better, reduces air bubbles, and gives a clean surface finish. In art and craft, it is very useful for detailed molds, thin casts, and smooth finishes. In construction, it is widely used in concrete for better strength and workability.
Features / Benefits:
- Improves flow without adding extra water
- Reduces bubbles and surface holes
- Gives smoother, cleaner cast finish
- Increases strength by lowering water content
- Helps fill fine details in molds
- Saves material by reducing water use
Applications / Uses:
- Gypsum and POP casting (molds, decor items)
- Cement crafts, planters, tiles
- Resin-style smooth finishes in plaster
- Precast concrete and construction mixes
- High-strength mortar and grout
How to Use (Simple Guide):
- Add 0.1% – 0.2% of total dry weight (Example: 1kg powder = 1g to 2g PCE)
- Mix well with dry powder first
- Then add water slowly and mix
- Adjust water level as needed (usually less water required)
Dimensions & Details:
- Type: Powder
- Color: Light white to off-white
- Solubility: Water soluble
- Recommended dosage: 0.1% – 0.2%
Package Includes: PCE Powder (100g or 250g pack)
⚠️ Cautions / Safety Notes
- Do not overdose. Too much PCE can cause slow setting or weak structure
- Always measure small amounts accurately
- Mix dry powder well before adding water to avoid clumps
- Reduce water gradually. Do not keep original water ratio
- Wear a mask when handling powder to avoid inhaling fine dust
- Avoid contact with eyes and prolonged skin contact
- Keep away from moisture. Store in a sealed container
- Test small batches first before large casting
- Keep out of reach of children
Best for getting smoother, stronger gypsum or cement casts with less water. Works well for both small craft work and larger mixes.
