Self-leveling compounds create smooth, even floors before final flooring installation. These special mixtures flow easily and settle into a flat surface without much effort. There are two main types: cement-based self-leveling compounds and gypsum-based self-leveling compounds. Each type has different ingredients, properties, and uses.
Both types of self-leveling compounds need special additives to work properly. These additives help make the compounds stronger, easier to pour, and longer-lasting. LANDU, a trusted specialty chemicals manufacturer, offers high-quality, eco-friendly additives that improve bonding strength and wear resistance. Our expertise ensures you get the perfect floor every time.
"The right self-leveling compound additives can mean the difference between a floor that lasts for years and one that fails prematurely." - LANDU Technical Team
Self-leveling compounds rely on several key additives to perform well. These include cellulose ethers, binders, defoamers, and water reducers. At LANDU, we offer a complete range of chemical additives to improve your self-leveling compounds. Our products solve common problems and deliver outstanding results.
LANDERCOLL, our core brand, makes high-quality cellulose ether. Our LANDERCOLL Hydroxypropyl Methyl Cellulose (HPMC) works great in self-leveling compounds because it:
These benefits make self-leveling compounds more waterproof and durable, ensuring they last longer.
LANDU ACCURATE provides top-quality Redispersible Latex Powder (RDP) that improves self-leveling mortar flow and durability. This powder makes self-leveling compounds easier to pour and apply. Additionally, RDP enhances tensile and flexural strength, preventing cracks when the floor faces stress.
Our innovative NOVASTAR brand develops various chemical additives. For self-leveling compounds, NOVASTAR offers Polycarboxylate Superplasticizer and Powder Defoamer. These additives greatly improve flow properties and help maintain workability longer. They also reduce bleeding and ensure a beautiful, smooth surface after leveling.
NOVASTAR polycarboxylate superplasticizer (PCE) comes in powder and flake forms. This additive gives cement-based self-leveling compounds excellent flow properties with less water. It also maintains good cohesion while flowing freely, preventing separation and bleeding.
Furthermore, PCE significantly reduces shrinkage, keeping the compound slightly expanded in most cases. This prevents common construction problems with self-leveling products. According to research by the Concrete Institute of America, PCEs improve workability and reduce cracking substantially.
NOVASTAR powder defoamer effectively eliminates foam in cement-based self-leveling compounds. By reducing bubbles, this additive makes the material more compact and stronger. It also improves flow, helping the compound fill spaces and create a level surface more effectively.
LANDERCOLL HPMC holds water in the mix, slowing evaporation in cement-based self-leveling compounds. This extends working time and helps achieve flatter floors. By forming a protective film and improving cohesion, HPMC reduces drying cracks and enhances overall durability.
LANDU ACCURATE RDP powder plays a crucial role in cement-based self-leveling compounds. It improves flow, making leveling easier and reducing hollowing and cracking during installation. RDP also strengthens the bond between the compound and the base layer.
Additionally, RDP adds flexibility, preventing cracks when the base layer moves or vibrates. This makes self-leveling compounds more reliable in real-world conditions.
NOVASTAR Polycarboxylate Superplasticizer, also called a water reducer, greatly enhances the flow of gypsum-based self-leveling compounds. It changes how the solid and liquid components interact, releasing water trapped by gypsum particles and reducing water requirements.
This additive works through both electrostatic repulsion and steric hindrance. These mechanisms prevent gypsum particles from clumping together, creating a stable isolation film that improves workability.
NOVASTAR Gypsum Retarder powder contains innovative amino groups that slow down gypsum hydration in self-leveling compounds. This delay allows the mixture to flow freely and spread evenly under gravity. It also provides more working time for mixing, pouring, and spreading before setting begins.
LANDERCOLL HPMC provides excellent water retention in gypsum-based self-leveling compounds. This ensures complete hydration and stronger mechanical properties. It also helps control curing time, allowing rapid hardening under proper conditions and improving construction efficiency.
