3M Gray Polyurethane Sealant, 310 ml, Cartridge, 08684

3M™ panel sealants are high-performance, one-component polyurethane sealants developed for bodywork applications and designed to cure upon contact with moisture in about 24 hours. They offer excellent adhesion to metal, wood, and plastic, maintaining good flexibility even after complete drying.

Thanks to their thixotropic formulation, they do not drip or sag, and provide a hold resistant to weather agents, water, oils, and fuels. They can be applied directly on unpainted steel and welded while still fresh (within 35 minutes). After at least 45 minutes from application, the product can be overpainted with common water-based or solvent-based systems.

Ideal for sealing joints, weld beads, and body panels, 3M™ sealants withstand temperatures ranging from -40 °C to +90 °C (up to 120 °C for short periods), providing durable and professional protection in any condition.
