Sika 291 Black
Sikaflex-291 is a marine sealant that is easy to use and meets international standards. It is a one-component polyurethane sealant that cures when exposed to moisture in the air, creating a strong and durable rubber-like material.
This versatile product can be used for various sealing applications in marine construction and bonds well to commonly used materials like wood, metals, ceramics, and certain plastics.
However, it should not be used on plastics that are prone to stress cracking. Once it has cured, Sikaflex-291 can be easily sanded if necessary.
