Acting as a parting compound to prevent accidental brazing of touching surfaces during furnace brazing, Nicrobraz® White Stop-Off™ can be applied by brushing, dipping, spraying, or with a syringe to small areas.

Water-based stop-off is nonflammable and odorless. Choose from our selection of brazing stop-off in a wide range of styles and sizes. Same and Next Day Delivery.

Stop Offs are parting compounds designed to prevent flow of molten filler metal into areas where it is not needed. Stop off compounds are a suspension of a metal oxide in a solvent base. A variety of leading brand braze stop off compounds are available from VBC Group. These include WCL Green Stop-off ™ and Morgan Stopyt ™.

May 28, 2020 · A brazing "stop-off" is supposed to be something that "stops" molten brazing filler metal (BFM) from flowing into areas where it is not supposed to be, thus keeping it "off" surfaces that are supposed to remain clean and free from the presence of any BFM.

Braze-Stop Products will stop the flow of molten braze alloy and flux from going where you don’t want it. Continental Braze Supply offers 4 versions of our braze inhibitor. We offer a dispensable product along with a brushable type for both Dip Brazing and Vacuum applications.

Jul 5, 2016 · Stop-Off can be useful when brazing precise assembly designs involving threads or holes-where braze alloy would impede functionality. Applying Stop-Off to these areas before brazing prevents alloy from flowing to those surfaces.

Lucas-Milhaupt 470 Stop-Off is specially formulated for furnace- and vacuum-furnace brazing. It can be used in torch, furnace, induction, and resistance brazing. A key benefit is minimization of post-braze cleaning, as 470 is reduced to a powder which is easily removed.

May 28, 2020 · Because oxides are so good at stopping the flow of molten BFMs, brazing stop-off compounds are made as blends of a variety of metallic-oxides and are packaged in a variety of forms: liquids, pastes, powders, sprays, or tapes (to name just a few).

Stop-Off, as has been stressed earlier, is supremely effective as a barrier against filler metals. When a flux is used (as in torch brazing), the stop-off layer should be heavy and the flux layer thin. A heavy layer of flux will lower the effectiveness of the stop-off layer. (When using flux, Nicrobraz Yellow Stop-Off is generally most effective.)

Designed to protect metal surfaces from the flow of molten brazing filler metal or to prevent metal surfaces from adhering to each other during furnace brazing, Wall Colmonoy’s Stop-Off products are available in two grades: fast drying Type I (lacquer based), and …
