Thickening mechanism

– In non-associative thickening mechanism, the thickening efficiency is based on the molecular weight of the thickener. High molecular weight thickener gives high thickening efficiency.

Non-associative thickening

– In associative thickening mechanism, the thickening efficiency is not only come from the molecular weight of the thickener but also come from the interaction of the hydrophobic groups in the thickener with the paint raw materials such as latex, pigment, surfactant, dispersant etc. A hydrophobic latex such as styrene acrylic will have stronger interaction with associative thickener than a hydrophilic latex such as vinyl acrylic. A stronger interaction will lead to higher paint viscosity so we required less associative thickener for styrene acrylic paint as compared to vinyl acrylic paint.
