  • Masking 101 Helpful Hints
    • Push down hard! This is a pressure sensitive adhesive tape - pressure is required for it to adhere properly to parts.
    • Clean parts thoroughly before applying tape.
    • Apply tape to dry surfaces only.
    • Tape is for intermittent, one-time use only.
    • Store rolls on end in a cool, dry place.
    • Shelf life is 12 months from date of purchase.

      Technical FAQ: Saint-Gobain CHR 2925-7

    • What is the maximum operating temperature for 2925-7 tape? The Saint-Gobain CHR 2925-7 is rated for a continuous operating temperature range of -100°F to 500°F (-73°C to 260°C). Its silicone adhesive is specifically formulated to maintain a strong bond under high-heat conditions without degrading.
    • Can 2925-7 be used for HVOF and Plasma Spray masking? Yes. This tape is specifically engineered for high-intensity thermal spray applications, including HVOF (High-Velocity Oxy-Fuel) and plasma spray. The laminated foil and glass cloth construction provides the necessary abrasion resistance to withstand grit blasting and the thermal reflectivity needed for intense spray cycles.
    • What is the total thickness of the F2925-7 laminate? The total tape thickness is 0.007 inches (7 mil). This includes a 0.0025-inch backing thickness, providing a low-profile mask that remains highly conformable to irregular surfaces and complex geometries.
    • How do I ensure the best adhesion for thermal spray masking? To prevent "flagging" or lifting during high-pressure spray cycles, parts must be thoroughly cleaned and dried before application. As a pressure-sensitive tape, you must apply firm pressure during installation to fully activate the silicone adhesive bond.
    • What is the shelf life of Saint-Gobain 2925-7? When stored on end in a cool, dry environment, this tape has a recommended shelf life of 12 months from the date of purchase.
