As shown in the figure, associative thickeners are composed of polymers containing thousands or tens of thousands of molecular weights composed of hydrophobic and hydrophilic groups. These are dispersed in aqueous resin emulsion or latex, and act as thickening agents. The figure shows that the thickening mechanism forms a network structure by combining the hydrophobic parts of an emulsion with the hydrophobic parts of resin or thickener. Associative thickeners associate with each other and exhibit assertive thickening behavior. However, the network structure is structurally weaker than the polymeric thickener described later, so the thickening force is also relatively weak. We offer a variety of associative thickeners suitable for the various viscosity behaviors required by customers.
Synthetic polymer thickener is composed of polymers with a molecular weight of hundreds of thousands or millions of (primarily acrylic) acid molecules. Aqueous polymers with large molecular weights exhibit thickening properties when dissolved in water and exhibit a mechanism by which macromolecular chains are entangled. There are two main types of synthetic polymers. One is an aqueous type in which a polymer is dissolved in water, and the other is an emulsion type in which a polymer is emulsified in water. The emulsion-type thickener exhibits a thickening effect through an alkali dissolution process, which can be divided broadly into ASE (alkali-soluble emulsion) and HASE (hydrophobically modified alkali-soluble emulsion). ASE does not move associative groups, whereas HASE increases thickening through the introduction of associative groups. We offer a wide range of thickeners providing liquidity and thickening to meet the needs of customers.VIEW PRODUCT LIST
These products are used for thickening slurries in various electronic material fields. Using a thickener can increase the slurry's viscosity and coating thickness to prevent sedimentation of the slurry particles.VIEW PRODUCT LIST
