LOCTITE 587TM Automotive Gasket Maker & Sealant - Silicone Sealant
Basic Properties
LOCTITE 587 is a one-component oxime silicone sealant in metallic blue paste form (uncured). With thixotropic properties to minimize migration, it cures at room temperature (RTV) and is designed for gasket replacement/dressing in automotive engines, withstanding temperatures up to 260°C.
Core Characteristics
It delivers superior adhesion strength and flexibility, enhancing load-bearing and shock absorption. With excellent bonding to diverse substrates and outstanding resistance to automotive engine oils, it is ready-to-use without mixing, forming durable seals as a direct replacement for conventional gaskets.
