PSI (together with Whitford, its parent company) has a remarkably extensive Quality Control and Development Laboratory. This is an area where, as a private company (with no disinterested shareholders to question the expense), PSI has been able to set itself apart from the competition. We have equipment capable of measuring:

• Water content
• Grind particle size
• Viscosity
• Extrusion rates
• Thixotropy and work life.
• Tack-free time
• Tensile strength
• Shear adhesion
• Peel adhesion
• Hardness
• Modulus
• Accelerated weathering.

Additional lab capabilities range from complete computerized color-matching to contact-angle measurement. Among the lab equipment available for specialized testing are:

• TA Instruments R200 Rheometer
• Horiba Particle Size Analyzer
• Gas Chromatograph
• Dynisco Melt-Flow
• Fourier Transfer Infra-red
• Spectrophotometer.
