Marine-Grade Polyurethane Sealant
3M 06564 is a one-component polyurethane adhesive sealant supplied in a 10 oz cartridge for marine and general maintenance bonding. The black formula adheres to fiberglass, gelcoat, metal, plastic and wood in above- or below-waterline applications. It meets ASTM C661 and ASTM D412 standards for professional use.
250 % Elongation for Flexible Joints
The cured sealant stretches up to 250 percent without losing adhesion, allowing bonded assemblies to absorb vibration, hull flex and thermal cycling. This elongation capacity is the primary indicator that the product will maintain a waterproof seal on moving substrates where rigid adhesives would fail.
Paintable Finish with 50-Minute Working Time
After application the material remains workable for 50 minutes, giving installers time to tool joints and reposition parts before skin-over begins. Full cure occurs in one day, after which the surface accepts paint for cosmetic matching or UV protection without additional priming steps.

Questions about this item
What does the 250 percent elongation mean once the sealant is applied?
It means the cured bead can stretch to two and a half times its original length before breaking, letting joints move without splitting.
What does the ASTM C661 and ASTM D412 listing cap in practice?
Those standards confirm the sealant meets recognised benchmarks for adhesive strength and rubber-like elongation performance.
What does the 10 oz cartridge need to fit or mount in a caulking gun?
It fits any standard 10 oz cartridge gun; no special adapter or frame is required.
