PU204 Loop Sealant
PU204 is a cold pour adhesive designed to encapsulate loop sensors, protecting them from extremes of temperature as well as moisture ingression.
It is also strong enough to protect the loops from objects such as road grit which, with its sharp edges, can cut into the loops.
PU204 comes in an easy to use kit form. Simply pour all of the hardener into the resin and mix together preferably with an electric drill and an appropriate mixing attachment or a mixing stick. With correct mixing, perfect results will be obtained every time.
PU204 is available in 5kg kits.
A typical installation uses approximately 10 kits per lane.
Like the majority of our products, PU204 is non hazardous and therefore easily shipped around the world.
