Surface Science

Wetting, Contact Angle and Surface-Energy Testing

Tandell applies controlled surface-science measurements to understand how liquids interact with powders, films, polymers, metals, plant surfaces, battery components, and other defined substrates.

What we evaluate

Controlled variables. Relevant outcomes.

The final design is selected around your product format, use conditions, competitive set, target claim, and required level of control.

Static and dynamic contact angle
Surface and interfacial tension
Surface free energy and comparative wettability
Spreading, retention, absorption, and time-dependent wetting where applicable

Methods & protocols

Sessile-drop and captive-bubble approaches where appropriate
Dynamic and equilibrium tension measurements
Controlled substrate preparation and conditioning
Concentration, time, temperature, and formulation comparisons

What you receive

Quantitative wetting and surface-property data
Material or formulation ranking
Concentration-response and process insight
Development, troubleshooting, and supplier-comparison evidence

Project coordination

Method-selection guidance
Sample and timing coordination
Direct technical communication
Clear final reporting

Specialized programs

Go beyond a single cleaning score.

Product wetting

Compare how formulations spread, retain, penetrate, or recede on controlled substrates under defined application and conditioning.

Material surface energy

Characterize and compare surface state, treatment effects, contamination, ageing, or supplier differences using contact-angle-based measurements.

Application-specific studies

Translate battery, agricultural, polymer, surfactant, or cleaning questions into clearly bounded laboratory measurements without implying full-system certification or regulatory approval.

Related expertise

Connect application testing with measurement.

Surface tension, contact angle, foam structure, microscopy, colour, gloss, rheology, and controlled separation analysis can help explain why products perform differently.
