STOP-OFFS
Common Trade NamesDescriptionCommon Uses
Type I Green Solvent Based Stop-off Surface protection. Prevents filler metal from bonding to a protected surface, May also be used as a masking agent for thermal sprayed metallic coatings.
Type II Green Water Based Stop-off Surface protection. Prevents filler metal from bonding to a protected surface, May also be used as a masking agent for thermal sprayed metallic coatings. Also available in pens.
Type II Yellow Water Based Stop-off General purpose stop-off used in controlled atmosphere furnace and torch brazing, as well as in molten salt bath dip brazing. Can be used on almost any base metal except reactive metals.
Type I White Solvent Based Stop-off Acts as a parting compound. Special grade designed for furnace brazing. Prevents accidental brazing of mating surfaces, stacked parts, or parts to fixtures. Prevents flow of molten brazing filler metal, and easy to remove.
Type II White Water Based Stop-off Acts as a parting compound. Special grade designed for furnace brazing. Prevents accidental brazing of mating surfaces, stacked parts, or parts to fixtures. Prevents flow of molten brazing filler metal, and easy to remove.
Type II Red Water Based Stop-off Acts as a parting compound and filler metal barrier. Works on any base metal surface and designed for furnace use. Residue is easily removed and soluble in dilute acid.
Type I Orange Solvent Based Stop-off Prevents accidental brazing of mating surfaces and unwanted flow of filler metal. Special formula for very high-vacuum furnace applications and for use with Titanium and Zirconium. Used in super-plastic forming operations.
Type II Orange Water Based Stop-off Prevents accidental brazing of mating surfaces and unwanted flow of filler metal. Special formula for very high-vacuum furnace applications and for use with Titanium and Zirconium. Used in super-plastic forming operations.
Type II Blue Water Based Stop-off Performs in extremely high temperatures. Formulated for use on reactive base metals such as Titanium and Zirconium.
White Stopyt Solvent Based Stop-off Aluminum oxide based stop off compound for furnace brazing applications.
Pink Stopyt Type 62A Solvent Based Stop-off Yttria oxide based stop-off compound for high temperature furnace brazing applications.
1AL Braz Stop Water Based Stop-off Aluminum oxide based stop off compound for furnace brazing applications.
1YT Braz Stop Water Based Stop-off Yttria oxide based stop-off compound for high temperature furnace brazing applications.
