Paints, Coatings & Inks

• Architectural and decorative coatings
• Automotive coatings
• Industrial coatings
• Printing inks
• Functional coatings (barrier, conductive)

• Poor leveling or surface defects (e.g., orange peel, sagging)
• Pigment sedimentation during storage
• Inconsistent viscosity across batches
• Changes due to thermal degradation
• Uncontrolled Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing or drying behavior

With NETZSCH solutions, you can:

• Optimize formulation performance
• Prevent defects before production
• Improve stability and shelf life
• Ensure reproducible quality
• Accelerate development cycles

Rheology is critical for paints, coatings, and inks.

Analyze:

• Shear-dependent viscosity (brush, roller, spray)
• ThixotropyFor most liquids, shear thinning is reversible and the liquids will at some point in time gain their original viscosity when a shearing force is removed.Thixotropy and recovery behavior
• Yield StressStress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area). Samples having a circular or rectangular cross section can be compressed or stretched. Elastic materials like rubber can be stretched up to 5 to 10 times their original length.stress (stability vs. flow)
• Viscoelastic properties

Optimize:

• application behavior
• leveling and film quality
• formulation stability

Understand how temperature affects your system:

• Glass transition (Tg)
• Thermal stability and degradation (TGA)
