Tổng quan về sản phẩm
LOCTITE 510 is a one-component, anaerobic, form-in-place gasketing sealant formulated to seal rigid, machined metal flanges. It cures when confined between close-fitting metal faces in the absence of air, creating a robust seal that resists high temperature and chemical exposure. It fills surface imperfections (up to ~0.25 mm), increases torque capacity, and adapts to flange irregularities without needing a pre-cut gasket.

Hướng dẫn sử dụng
-
Chuẩn bị bề mặt
Remove old gasket sealants; clean surfaces thoroughly (e.g. LOCTITE SF 790 for removal, LOCTITE SF 7070 for degreasing). -
Activator (if needed)
For passive metals or low-temperature conditions, LOCTITE SF 7649 may be used to accelerate cure. -
Đơn đăng ký
Apply a continuous bead of LOCTITE 510 onto one flange surface (near inner rim) and encircle all bolt holes. For larger flanges, roller application is possible. -
Assembly / Torque
Assemble flange and tighten bolts promptly. Wipe off excess squeeze-out before curing (exposed portions won’t cure without confinement). -
Curing / Handling
Provides an immediate low-pressure seal; full cure as per TDS. Pressure testing should be delayed until adequate cure. -
Disassembly / Repair
Disassemble with hand tools. Use jacking screws or recesses to separate flanges. Use LOCTITE SF 790 or a suitable solvent + scraper to remove cured sealant.
Include instructions and caveats: avoid overapplication, ensure confinement, allow full cure before pressure.
Câu hỏi thường gặp
-
Q1: What is the maximum gap LOCTITE 510 will fill?
A1: Approximately 0.25 mm (0.01″) unprimed. -
Q2: Can LOCTITE 510 be used on coated or passive metals without a primer?
A2: Yes, it can often cure without primer when confined between metal surfaces. -
