The paste-formulaton dispenses from a standard cartridge, cures to a Shore A 55 elastomer in about 24 hours, and delivers strong tensile and shear performance. It resists movement and maintains adhesion across the product's operating range when applied at recommended temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eHow does 3M 560 perform on different materials and joints?\u003c\/h3\u003e\n\u003cp\u003e3M 560 bonds to many common construction and mechanical substrates, offering an elastic seal that accommodates joint movement.

It is ideal for sealing and bonding applications that require good mechanical strength, flexibility, and a black finish—especially where vibration, thermal cycling, or some joint movement will occur. For jobs outside the listed temperature or chemical exposure limits, test adhesion and performance first or consult product data for alternatives.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can 3M 560 be painted after curing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Some paints adhere to cured 3M 560; test a small area first.
