Application Solutions - FAQ

Which products work best for EIFS and exterior insulation mortar?
  • HEMC cellulose ether matched with flexible RDP is the optimal combination. It delivers excellent water retention, weather resistance and deformation resistance, effectively avoiding exterior wall cracking under long-term outdoor exposure.
  • RDP enhances internal cohesion, surface hardness and adhesion of gypsum products. It improves wear resistance and low-temperature flexibility, reduces brittleness and peeling, and stabilizes overall construction and finished-wall performance.
  • Viscosity, substitution degree and particle fineness are key factors. Different ether types and dosage ranges will directly adjust water retention, anti-sagging and open time to adapt to different mortar construction scenarios.
  • All series adopt low-VOC, environmentally friendly formulations, compliant with mainstream green building standards. Stable raw material control ensures no harmful volatiles, suitable for indoor and outdoor green building projects.
  • Dosage varies by application. Cellulose ether is added in small doses for thickening and water retention, while RDP dosage is adjusted based on bonding and flexibility demands. We provide technical dosage guidance for customers.
  • Formula compatibility is verified in advance. Reasonable compounding of cellulose ether, RDP and PCE can optimize fluidity, strength and workability, meeting the demands of self-leveling and high-strength mortar.
  • It improves water retention, extends open time, and prevents sagging. It enhances thixotropy for non-slip application, ensuring strong bond strength even on vertical surfaces.
  • It improves water retention, extends open time, and prevents sagging. It enhances thixotropy for non-slip application, ensuring strong bond strength even on vertical surfaces.
  • It optimizes workability and water retention, preventing premature drying, cracking, and powdering. It ensures smooth, uniform spreading and consistent finish.
  • They enhance flowability, anti-segregation, and leveling performance. Combined with PCE, they ensure uniform thickness and smooth surfaces without bleeding.
  • They act as thickeners and stabilizers, improving viscosity, suspension of solids, and rheology. They enhance cleaning performance and product texture.
  • Yes, they meet cosmetic-grade purity standards, are low-irritation, and comply with global safety regulations, suitable for use in shampoos, creams, and body washes.
  • They act as stabilizers and thickeners, preventing sedimentation, improving mouthfeel, and extending shelf life in juices, dairy drinks, and syrups.
  • Yes, they improve moisture retention, texture, and stability. In baked goods, they enhance softness; in fried foods, they reduce oil absorption and improve crispness.
  • It acts as a matrix material, controlling drug release rate and prolonging efficacy. It ensures stable dissolution and consistent bioavailability in oral formulations.
  • They form uniform, flexible films for tablet coating and stable matrices for vegetable capsules, ensuring controlled dissolution and improved drug stability.
  • They act as rheology modifiers and fluid loss control agents, improving drilling fluid viscosity, suspension, and filtration control under high-temperature conditions.
  • In ceramics, they improve green strength and workability; in textiles, they act as thickeners and binders, enhancing dye stability and printing definition.

Customer Application Cases

ThomasR&D Manager, Germany
"We were struggling with tile slippage on vertical walls and inconsistent bonding strength. After switching to Landu HPMC, our production team noticed the difference immediately. Open time went from 15 to 25 minutes, and we finally passed EN 12004 certification on the first try."
ElenaProduct Development Lead, Spain
"Our wall coatings had a persistent sagging problem on vertical surfaces, and applicators kept complaining about poor pattern retention. We tried Landu HEMC as a direct replacement. Now sagging is no longer an issue, pattern definition is much sharper, and our customers report less material waste on site."
MateuszFormulation Chemist, Poland
"We wanted a clean label thickener that wouldn't compromise foam stability. Many options failed. Landu HEC gave us the viscosity we needed—around 8,000 cP—without clouding the formula. Foam lasts longer, the texture feels premium, and our compliance team approved it immediately."
