Syma 840 is a high quality single-component polyurethane
putty that polymerises quickly with ambient humidity, leading to
a high module joint.
Characteristics
Paintable. Quick polymerisation without retraction. Strong initial
grip and great adhesive power. Its high module enables an elastic
adhesion. Excellent resistance to UV radiation and many chemical
agents.
Applications
Elastic and waterproof sealing in construction and
civil engineering. Sealing of joints exposed to chemical
agents on passable floors. Sealing and joints in automobiles,
containers, caravans, boats, metal pieces… |
