HMS65 Mastic Adhesive Heat Shrinkable Sleeve/2 Layer/without primer/ISO 21809-3 14A-1
-2 Layer Field joint Coating System
![]() |
HMS 65 Mastic heat shrinkable sleeve 2-layer field joint coating system are engineered for ready-to-fit assembly for the corrosion protection of field girth weld joints in water supply or gas distribution and transmission networks, especially for use in low & middle shear or low stress environments in moderate climates, or basting application is not available section.
HMS65 is compatible with standard pipe coatings, can also be used for coating bare, replacement pipe sections and large radius bends. The system is designed to be applied with minimum preheating and is ideal for large diameter water pipe.
(Above pipe diameter DN750 (30") in high shear and high stress environments, the use of HCS 65, HSS 60/80 is recommended).
Construction: Two-layer system
First layer: Low preheat viscoelastic mastic sealant (HMS 65)
Second layer: Radiation cross-linked, high density polyethylene backing with TIP (Temperature Indicator Pattern)
Features & Benefits
• Excellent mastic adhesive allow for lower installation pre-heat temperature and super bonding to coating, offer fully resistant to shear forces induced by soil and thermal movements.
• Superior cathodic disbondment and offers the optimum barrier long term protection against corrosion.
• Easy field application, no need blasting surface preparation, saves time & cost, HMS can be installed quickly and easily in most environments.
• Pattern backing provides a “heating temperature indicator” for application of heat. Ensures correct application heating.
• Covers a wide range of operating temperature ratings from -25°C to 65°C, offers a solution for nearly every application.
