What is the elastic recovery rate of this PU sealant?
This PU sealant typically achieves an elastic recovery rate exceeding 80%, making it highly effective at accommodating joint movement, vibration, and thermal expansion or contraction in building structures.
Does PU sealant require a primer before application?
In most cases, no primer is required. The sealant bonds tenaciously to a wide range of common construction substrates, including concrete, masonry, metals, wood, and most plastics, directly without additional priming steps.
What temperature range can this PU sealant withstand?
This sealant is formulated to maintain performance across a wide temperature range, typically from -40°C to 80°C or more, ensuring reliability in both extreme cold and high-heat environments.
How much joint movement can this sealant accommodate?
The sealant can effectively bridge joint movements of up to ±25% to ±50% of the joint width without cracking, splitting, or losing adhesion, providing a durable and watertight seal over time.
Is this PU sealant resistant to UV exposure and weathering?
Yes. Thanks to its advanced polyurethane formulation, the sealant maintains color stability and performance under prolonged UV exposure, rain, and snow. It does not chip, peel, or become brittle over time.
What substrates is this PU sealant compatible with?
This sealant is compatible with a broad range of construction substrates including concrete, masonry, metals, wood, and most plastics, making it a versatile choice for a wide variety of building and sealing applications.
