Polycarboxylate Superplasticizer (PCE) products are high-performance additives that significantly enhance the flowability and mechanical strength of construction materials. They are fully compatible with cement and gypsum binders, as well as other common additives like defoamers and retarders, making them ideal for advanced concrete and mortar formulations.
Silicone Hydrophobic Powder (SHP) is a powdered water-repellent additive designed to enhance water resistance while preserving vapor permeability. Commonly used in waterproof building materials, SHP helps protect surfaces from moisture without trapping internal humidity, ensuring durability and breathability in construction applications.
Gypsum Retarder is a construction additive that slows the setting time of gypsum-based materials, such as plaster and board compounds. It provides extended working time, reducing the risk of premature setting that can lead to uneven surfaces or defects. LANDU’s gypsum retarder ensures smoother application and a more consistent finish.
Powder Defoamer, also known as an anti-foaming agent, is used to control and eliminate unwanted foam generated during mixing—especially when water or air-entraining admixtures are present. Excess foam can lead to surface defects, slower production, and material waste. By reducing foam formation, Powder Defoamer helps enhance processing efficiency and ensures a smoother, higher-quality final product.
Hydroxypropyl Starch (HPS) is a high-performance modified starch ether known for its superior functionality in construction applications. Among starch-based additives, HPS stands out with its excellent water solubility, pH stability, water retention, dimensional stability, and film-forming ability, along with strong resistance to enzymatic degradation. These properties make it a reliable additive for improving workability, consistency, and durability in dry mix formulations.
Polyvinyl Alcohol (PVA) Powder is a water-soluble polymer known for its ideal viscosity and excellent film-forming properties. LANDU’s PVA offers outstanding stability in oils, lubricants, hydrocarbons, and most organic solvents. It also provides superior chemical resistance and insulation performance. Thanks to its polyol structure, PVA can undergo esterification and acetalization, making it highly versatile for use in adhesives, coatings, construction materials, and more.
Polypropylene Fiber, also known as anti-cracking fiber, is a synthetic polymer fiber widely used in mortar and concrete to enhance strength, durability, and crack resistance. It is tough, heat-resistant, non-magnetic, and non-conductive—making it ideal for a variety of construction applications. Suitable for use in temperatures ranging from 0 to 100°C, this fiber helps improve structural integrity without affecting the material’s thermal or electrical properties.
