PU-30 Low Modulus Construction Polyurethane Sealant

PU-30 Low Modulus Construction Polyurethane Sealant

PU-30 is a one-component, moisture-curing polyurethane joint sealant designed to seal expansion, control, and connection joints in construction. Its "low modulus" formulation means it offers high elasticity and stretches easily under stress without putting undue pressure on the joint edges

∎Technical Data Table

Note：All data above were tested under special condition (7 days after full cured).

∎Product Description

PU-30 is a one-component moisture curable polyurethane sealant with good sealing and flexibility.

∎Key Features

● Low modulus and high elasticity

● Moisture-cure, no cracking

● Bonding well with many substrates, no corrosion and pollution to substrate

●One component, convenient to apply, non poisonous and odor less after curing, green and environmental

●High Movement Capability: Accommodates significant expansion and contraction caused by temperature fluctuations without cracking.

●Weather & UV Resistance: Highly durable against rain, sunlight, and extreme temperatures, making it suitable for both indoor and outdoor use.

● Primerless Adhesion: Bonds excellently to concrete, brick, natural stone, aluminum, wood, and glass.

● Permanent Elasticity: Cures into a permanently flexible rubber-like seal that does not shrink

∎Typical Applications

●Sealing of expansion and settlement joint of house building, plaza, road, airport runway, anti- all, bridges and tunnels, building doors and windows etc

●Sealing of upstream face crack of drainage pipeline, drains, reservoirs, sewage pipes, tanks, silos etc

●Sealing of through holes on various wall and at floor concrete  

●Sealing of joints of prefab, side fascia, stone and color steel plate, epoxy floor etc

• Expansion Joints: Used heavily in roads, plaza decks, bridges, and airport runways.

• Building Facades: Ideal for sealing perimeter joints around windows, doors, and prefabricated concrete elements.

• Civil Engineering: Suitable for tunnels, parapets, and retaining walls.

• Infrastructure: Used for sealing cracks in drainage pipelines, tanks, and sewage pipes
