    Another contributing factor to HEC's thickening mechanism is the formation of 'secondary structureshydroxyethyl cellulose thickening mechanism.' In aqueous solutions, HEC chains can associate through van der Waals forces or hydrogen bonding, forming aggregates or micelles. These secondary structures further enhance the viscosity by restricting the free movement of water molecules and increasing the internal friction within the solution.
    Moreover, redispersible polymer powder offers significant improvements in workability and water retentionredispersible polymer powder wiki. The consistency of the mix can be easily adjusted to suit different application methods, whether by brush, roller, or spray. The increased water retention also ensures that the material does not dry too quickly, allowing for more time to apply and level the surface before it sets.
