HVOF Tapes
The high particle velocity of HVOF results in extremely high abrasion and a rapid transfer of heat through the masking materials. In order to mask effectively against HVOF, masking materials, including tapes, must be strong enough to withstand both the high abrasiveness and high heat. Green Belting™ HVOF Tapes are proven performers that hold up exceptionally well against the HVOF spray while offering high conformability, and clean, residue-free removal.
Specifically formulated for GF-HVOF masking applications, Green Belting thermal spray masking materials are designed and engineered for:
- Abrasion Resistance - The recommended tapes will resist high abrasion which allows for the masking material to maintain its integrity while also providing clear, well-defined coating lines with little to no distortion or fraying.
- Strong Adhesion of Tapes - Adhesion to metal is key priority for any tape surviving GF-HVOF. The HMVT series of tape has very strong adhesion to metal which allows the tape to stay in place during the spray process. This strength is what allows these tapes to resist the high kinetic energy or force associated with GF-HVOF. This tape has strong adhesion to metal and to itself. The result of the strong adhesion is a masking tape that will stay firmly in place with no lifting or flagging.
- Resistance to Heat Transfer - The recommended Green Belting tapes are designed to resist extreme heat while also limiting the transfer rate of heat through the material. This trait is especially important with the HMVT series of tapes as protection of the adhesive is a key factor in the survival of the masking tape.
- Highly Conformable - The key to an effective GF-HVOF masking is conformability. Competing tapes are very stiff which limits their effectiveness. Our recommended tapes and compounds will conform easily to mask difficult or complex profiles. Superior conformability allows Green Belting products to be used for applications where competing tapes simply will not work due to lifting.
- Clean Release - Green Belting tapes leave no residue on removal after blasting and spraying. Adhesive residue can be a major problem for some competing thermal spray masking tapes. Green Belting masking products leave no adhesive residue which results in no need for any extra clean up and/or rework.
Problems that operators typically encounter with GF-HVOF include: extremely high abrasion, fast transfer of heat through masking materials and high kinetic energy or force. A combination of Green Belting tapes and MSSA Masking Compounds can offer unique solutions to tackle these challenges.
