Our Capabilities
Contact angles and Surface Free Energy
Determining wetting characteristics of solids and liquids. Static and dynamic measurements.
Methods
- Image capture contact angle measuring instrument
- Surface free energies,
- Interfacial energies ( surface tension),
- Advanced and receded contact angles.
- Pendant drop .
Applications of Contact angle and surface free energy analysis
- Images to demonstrate the matching of ink and substrate wetting characteristics to avoid ‘bleed’ or ‘bead’.
- Technical material property determination for specification, QC or indication of coating faults.
- Detection of surface treatments and ageing on polymers and materials
- Adsorption studies for paper, wood, waterproof-breathable fabrics etc.
- Wetting characteristics of single fibres for composite development.
- Personal care products
- Kinetic interfacial energy studies for surfactants used in various processes including polymerisation.
The MSG advantage
- Software enables more accurate test methods than other similar instruments
- Kinetic studies by movie function, up to 50 frames/second
- Wettability envelopes
- Ambient and elevated temperature capability for solids and liquids (up to 400 °C)
