Single-Component Pressure Sensitive Paint

UniCoat Pressure Sensitive Paint

(Product ID: UNC-12)

       UniCoat is a single-luminophore pressure sensitive paint (PSP) packaged in an aerosol can for ease of application.  UniCoat has slightly higher temperature sensitivity and slightly lower pressure sensitivity than UniFIB PSP, but is a simple shake and spray application at a lower cost than other products and is ideal for academic purposes.  This single coat application paint may be applied directly to most materials.  UniCoat is an effective quantitative PSP well suited for isothermal environments (large metal models and temperature controlled tunnels) or where strong pressure variations are present (transonic and supersonic flows).  UniCoat is recommended for introductory PSP users who seek an inexpensive paint for the purpose of developing their PSP capabilities.

UniFIB Pressure Sensitive Paint

(Product ID: UF-XXX)

            UniFIB is a bright single-luminophore pressure sensitive paint (PSP) formulated to be applied with paint spraying equipment as a single component PSP optimized for maximum luminescent signal while maintaining high pressure sensitivity and low temperature sensitivity.  This paint formulation may be excited effectively from 370-nm to 520-nm, however, 400-nm radiation from LM2X-400 LED modules is recommended.  The paint may be applied to most materials, though models constructed of materials that may be attacked by solvents, such as plastic or rapid prototyping resins, should be coated with a base coat such as SCR-100 (Screen layer) or FB (FIB basecoat).  The calibration of UniFIB is very stable and repeatable thus UniFIB is recommended for advanced/professional PSP users who seek high-quality data up to transonic flow conditions.

Binary Pressure Sensitive Paint

Binary UniCoat Pressure Sensitive Paint

 (Product ID: BUNC-12)

        Binary UniCoat is a dual-luminophore pressure sensitive paint (PSP) packaged in an aerosol can for ease of application.  The binary PSP approach involves acquiring data from two distinct luminescent dyes and using these signals to compensate for errors caused by model displacement and deformation.  Binary UniCoat has higher temperature sensitivity and lower pressure sensitivity than FIB based paints as shown in the calibration below.  A desirable feature of Binary UniCoat is ease of application.  Simply shake the can and spray the surface.  The result is a single coat application paint that may be applied directly to most materials.  Binary UniCoat is an effective quantitative PSP in isothermal environments (large metal models and temperature controlled tunnels) or where strong pressure variations are present (transonic flows).  It is also effective in compensating for errors due to model displacement and deformation.  Binary UniCoat is recommended for introductory PSP users who seek an inexpensive means to gain experience with binary paints.

Binary FIB Pressure Sensitive Paint

(Product ID: BF-XXX)

      Binary FIB pressure sensitive paint (PSP) is a dual-luminophore, single application PSP formulated to be applied with paint spraying equipment.  The binary paint approach involves acquiring data from two distinct luminescent dyes and using these signals to compensate for errors caused by model displacement and deformation as well as temperature. One dye is pressure and temperature sensitive and the other dye is temperature sensitive only. The ratio of the signals from the two dyes allows the temperature sensitive signal to be isolated from the pressure sensitive signal. The temperature sensitivity of the paint can be minimized over a wide range of temperatures and pressures as shown in the calibration below. The paint may be applied to most materials, however a white base coat such as SCR-XXX (Screen layer) or FB-XXX (FIB basecoat) is recommended. Models constructed of materials that may be attacked by solvents such as plastic or rapid prototyping resin should be coated with a screen layer or FIB basecoat. The calibration of Binary FIB is very stable, repeatable, and exhibits very little temperature sensitivity.  Binary FIB is recommended for advanced/professional PSP users who seek high quality data in low-speed environments or where temperature gradients are larger and have a greater impact on the signal-to noise ratio.

Base Coatings

PSP Screen Layer

(Product ID: SCR-XXX) 

The epoxy-based screen layer (SCR) is a two part formulation designed to be applied to surfaces using conventional paint spraying equipment to mask machining marks and stains or to mask surfaces that fluoresce and interfere with PSP or TSP data.  FIB basecoat also provides a uniformly reflective surface to minimize illumination errors and enhance the emission of PSP and TSP.  SCR comes in two parts and is mixed 1:1.  SCR provides the highest quality surface screen layer without superior solvent resistance and improved opacity.  The solvent resistance means PSP can be applied over it and removed many times without the need to reapply the screen layer each time. SCR needs to be fully cured before the PSP is applied by curing at elevated temperatures (90C for 3 hours) or by allowing a few days to air cure to prevent the screen layer from interacting with the PSP and compromising data. SCR is a permanent screen layer.  Shelf life is 3-months.

FIB Basecoat

(Product ID: FB-XXX)

      The FIB basecoat is a single application screen layer that is sprayed onto a model surface with paint spraying equipment to mask machining marks and stains or to mask surfaces that fluoresce and interfere with PSP or TSP data.  FIB basecoat also provides a uniformly reflective surface to minimize illumination errors and enhance the emission of PSP and TSP.  This formulation is recommended for surfaces where the screen layer and PSP or TSP absolutely must be removed from the surface using common mild solvents.
