Monitoring of Microstructure Evolution During a Film Formation Process - Rheolaser COATING

Optical Film Formation Analyzer

Rheolaser COATING allows a simple yet sensitive monitoring of microstructure evolution during a film formation process. In particular, the instrument precisely identifies open-time, touch-dry time, dry-hard time, and curing time. Because the instrument does not come in direct contact with the sample, it becomes possible to characterize various products, including resins, inks, paints, and polishes. The Rheolaser Coating’s open set-up enables the utilization of various substrates such as glass, metal, or ceramic.

Highlights of the Rheolaser Coating

Up to 4 Simultaneous Measurements

The Rheolaser Coating is able to analyze a maximum of 4 measurements at a time due to its adaptable and customizable set-up. This allows an instant sample comparison of  the drying times of various samples.

Contact-Free Technology

The MS-DWS technology enables drying mechanisms to be studied without contact but with high sensitivity. This provides more insight on the evolution of coating structures.

Drying Properties Characterization

  • Drying time (open-time, touch-dry time, dry-hard time)
  • Curing time
  • Film formation
  • Particle packing, particle deformation

Measurements on Adapted Substrates

Drying properties may  be evaluated on various materials such as ceramic, glass, metal, wood, or paper. The adaptation is dependent on product application and use.

Applications

  • Home and personal care
  • Paints and inks
  • General chemistry and polymers

Key Benefits

Utilizing an MS-DWS technology allows the Rheolaser COATING to be the most sensitive and accurate instrument available for determining coating drying properties.

The instrument operates at room temperature; however, it can be used in temperature conditions of up to 60 °C (heating cabinet).

The open instrument configuration feature allows operators to use the Rheolaser COATING with an Automatic Coater to fully control applied thickness or the vacuum plate when analyzing drying (on paper).
