VF160 Polycarboxylate Water Reducing Flake

VF160 is a solid flake form polycarboxylate ether (PCE) superplasticizer engineered for high water reduction and strong dispersion in cement-based systems. Unlike liquid PCE, VF160 dissolves fully in water and ships without freight restrictions on liquid content, making it a practical choice for exporters, dry mortar producers, and long-distance buyers. Luke Chemicals manufactures VF160 to deliver consistent particle size, fast dissolution, and reliable performance across a wide range of mix designs.

What Is VF160 Flake Water Reducer

VF160 is built on a polycarboxylate ether backbone with a comb-like molecular structure. The main chain anchors to cement particles while the side chains extend into the mix water, creating steric hindrance that keeps particles dispersed. This mechanism gives VF160 a higher water reduction rate at lower dosage than older generation water reducers such as naphthalene sulfonate (SNF) or sulfonated melamine (SMF). Because it is supplied as a flake rather than a liquid or spray-dried powder, VF160 offers easier handling, longer shelf stability, and simpler proportioning for dry-mix and OEM formulators.

Key Technical Properties

• Appearance: light yellow to beige flake
• Chemical base: polycarboxylate ether copolymer
• Solid content: high, typically above 90 percent (flake form)
• Water reduction rate: 20 to 35 percent depending on dosage
• Recommended dosage: 0.1 to 0.5 percent by weight of cementitious material
• Chloride ion content: low, suitable for reinforced and prestressed concrete
• pH: neutral to slightly alkaline in solution
• Solubility: fully soluble in water, no residue

Actual performance should be confirmed through lab trials with your specific cement, aggregates, and mix design, since raw material variation affects dosage and results.

How Does VF160 Improve Concrete and Mortar Performance

• Higher water reduction at lower dosage compared with conventional water reducers
• Improved workability and flowability without segregation or bleeding
• Better slump retention during transport and hot weather placement
• Increased early and late compressive strength through a lower water-cement ratio
• Reduced shrinkage and cracking risk in hardened concrete
• Good compatibility with retarders, air-entraining agents, and defoamers
• Uniform dispersion that supports smoother surface finish and reduced porosity

Where Is VF160 Used

VF160 is suited to a range of cement-based applications, including ready-mix and cast-in-place concrete, precast and prestressed concrete units, self-leveling and self-compacting concrete, dry-mix mortar and tile adhesive production, grouting materials, and plastering compounds. It performs well in projects that require long-distance pumping, extended workability windows, or high early strength, such as bridges, high-rise buildings, tunnels, and industrial floors.

Is VF160 Suitable for Dry Mortar and OEM Formulation

Yes. Because VF160 is a flake, it blends easily into dry powder formulations without introducing extra moisture, which makes it a common choice for tile adhesive, self-leveling compound, and pre-blended mortar manufacturers. Formulators can adjust dosage within the recommended range to fine-tune flow and open time for their specific product line.

How Should VF160 Be Dosed and Stored

Dosage typically ranges from 0.1 to 0.5 percent of total cementitious material weight, converted to solid content. The optimum rate depends on cement type, mix design, ambient temperature, and desired slump, so lab trials before full-scale use are recommended. VF160 should be stored in a dry, sealed, moisture-proof container away from direct sunlight. Under proper storage conditions, the product maintains stable performance for extended periods.
