Rheology Modifiers
A long lasting passion leading to accurate rheology solutions
Being always engaged in exploration and enhancement of rheology concept, we at Lamberti succeeded to build up substantial selection of natural and synthetic polymers. Our portfolio represents not only the competences we gained in industry, but also illustrates the long lasting path of our passionate work.
Acrylic Emulsions are conventional latices where hydrophobic monomers are emulsified and then polymerized to reach high molecular weights, colloidally suspended in water with appropriate surfactants. They are provided at low pH for a perfect aging stability even against microbiological attacks. They require a neutralization step for the polymer to become water soluble, and thanks to its neutralized carboxylic groups, they start to exhibit its rheological properties. Functionalizations and internal crosslinking easily allow us to target very specific rheology profiles and reach peculiar properties, such as suspending power, transparency or efficiency in complex surfactant systems.
From conventional latices to inverse emulsions
Acrylic Inverse Emulsions are viscous latices composed of water-swollen hydrophilic polymer particles, colloidally suspended in a continuous oil phase with a very low polarity thanks to appropriate emulsifiers.
This process allows us to obtain very high molecular weight polymers with outstanding properties, that render them suitable for applications like creams and balms for Personal Care, or screen printing pastes for Textile.
