Deliver professional-grade sealing performance with Loctite® Blue Maxx (SI 587) — a high-performance, metallic blue oxime silicone paste engineered for formed-in-place gasket and sealing applications. Designed for use in automotive, plant maintenance, and OEM manufacturing, this flexible silicone sealant provides exceptional resistance to heat, oil, and vibration, ensuring reliable, long-term sealing under extreme conditions.

Loctite 587 is a thixotropic paste that applies easily without running or sagging, forming a strong, flexible gasket that resists cracking and shrinking.
