It is vital that you know exactly what the chemicals are and what their flammable points are, so do your research before going near a chemical system. HEAT SHOULD NOT BE USED WITH A CHEMICAL SYSTEM.<\/li>\n<li>If it is not a chemical system, heat the area to 120\u00b0F (50\u00b0C) or higher. Using heat will expand and activate the metal as well as evaporate any water.<\/li>\n<li>Once the metal is warmed sufficiently, apply the Permabond HL126 to the joint being resealed, using either a paintbrush or a clean piece of cloth. Apply it liberally and put a couple of coats on so that it soaks right into any cracks, porosities, and spaces in the joint.<\/li>\n<li>Leave it to set.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h5><strong>Threadlocking pre-assembled fasteners<\/strong><\/h5>\n<ul>\n<li>Apply Permabond HL126 to the threads of the fasteners before inserting them into their respective holes. Except for closed or blind holes. For blind holes, also apply the sealant to the bottom of the hole to prevent air pressure from forcing the fastener out or leaving voids on the thread.<\/li>\n<li>Allow it to set.<\/li>\n<\/ul>\n<h5><strong>Threadlocking post-assembled fasteners<\/strong><\/h5>\n<ul>\n<li>Apply <a href=\"https:\/\/permabond.com\/tds\/hl126_tds-en\/?pdf=1\" target=\"_blank\" rel=\"noopener\">Permabond HL126<\/a> to the head of the fastener and then allow it to wick down the threads before insertion.<\/li>\n<li>Leave it to set and dry.<\/li>\n<\/ul>\n<p>When creating a tight seal or a solid bond, there is nothing quite as versatile as anaerobic sealants and adhesives. Whether locking threads or resealing leaky welding joints, having the right viscosity and strength in a product is key, and Permabond HL126 will have you covered for just about anything.<\/p>\n<p>When shopping for sealants and adhesives, they will usually be color coded according to their grading and recommended usage, making it easy to ensure you get exactly what you need.<\/p>\n<p>For further help and advice on weld sealing, threadlocking, or any adhesive or sealant application, please <a href=\"https:\/\/permabond.com\/contact-us\" target=\"_blank\" rel=\"noopener\">contact<\/a> Permabond.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Permabond HL126 Technical Data Sheet &nbsp; Permabond HL126, an extremely versatile product, can seal welds and function as a threadlocker due to its low viscosity and impressive strength.
