Fast-Responding Pressure Sensitive Paint 

TurboFIB PSP

(Product ID: TF-XXX)

       TurboFIB pressure sensitive paint (PSP) is a single-luminophore, single application PSP formulated to be applied with paint spraying equipment.  TurboFIB® provides many of the advantages of UniFIB® PSP, but with faster response (1 kHz) and reduced temperature sensitivity.  This paint formulation may be excited effectively from 380-nm to 550-nm, however, 400-nm radiation from ISSI LED modules is recommended for ideal response and pressure sensitivity.  The paint may be applied to most surfaces, though it is recommended that plastics and rapid prototyping resins first be coated with SCR-XXX (Screen layer) or FB-XXX (FIB Basecoat) to protect the surface from solvent damage.  The calibration of TurboFIB® (shown below) is very stable and repeatable thus TurboFIB is recommended for advanced/professional PSP users who seek high quality data. Paint is sold in quantities of 200-ml, 400-ml.  Custom quantities are available upon request. Surface coverage is approximately 1 m2 per liter.

(Product ID: FP-XXX)

FP Kit  

Porous, Fast-Response PSP is a three component, single-luminophore high speed pressure sensitive paint (PSP) formulated to provide high speed response (>10kHz) suitable for unsteady pressure   measurements with high pressure sensitivity.  The temperature sensitivity of these paints is higher than UniFIB® or TurboFIB so this PSP is best suited for isothermal environments.  This paint comes in three parts. Determine how much PSP you need for your application and measure out part A by volume.  Part B will be measured out 4% by volume of part A (a reusable measuring syringe is provided with the order for convenience). Shake the part A and B mixture well.  This mixture is to be sprayed with paint spraying equipment on to the surface of study with a wet application to achieve a smooth finish.  This application is the base layer. Once the base layer is dry, apply part C with paint spraying equipment, the overspray.  The overspray, part C, may be reapplied more than once.  A typical order would be a 100mL kit which would consist of three containers: 100 mL of part A, 5 mL of part B, 100mL of part C.
