NuFlex® 366 Marine Silicone Sealant

Product # 943660011

Ideal for above-water-line marine applications

NuFlex® 366 Marine Silicone Sealant is a 100% medium modulus, one component caulking material with a consistency similar to that of toothpaste. NuFlex® 366 cures to a tough, rubbery solid upon exposure to moisture in the air.

Because it does not flow due to its own weight, this sealant can be applied overhead or on sidewall joints and surfaces without sagging, slumping or running off. It adheres to clean metal, glass, most types of wood, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fiber, painted surfaces and many plastics.

NuFlex® 366 has good resistance to weathering, vibration, moisture, ozone and extreme temperatures. It may be applied in sub-zero weather without loss of extrusion or physical property characteristics and is effective to -46 °C (-50 °F).

- Resists vibration, heat, UV rays and moisture.
- Adheres to most marine substrates.
