∎Product Description
PU-30 is a one-component moisture curable polyurethane sealant with good sealing and flexibility.
Polyurethane sealants are used to seal joints in a wide variety of construction applications.
PU-30 is a low modulus joint sealant that is designed for construction and expansion joints with high movement capacity
in building and civil engineering construction. Uses include: between pre-cast concrete elements, joints in cantilever and
flat roofs, bridges and parapets, underpasses and tunnels and lightweight building materials. Advantages include ready for
use no site mixing, excellent adhesion to concrete, brick, natural and artificial stone, glass, ceramics, aluminium, stainless
steel and powder-coated metals. Sikaflex 15LM low modulus, one-part polyurethane sealant will not sag in both vertical and
overhead joints or when installed into vertical joints up to 35 mm wide. It has excellent aging and weathering properties.
It has no corrosion, no pollution, no pollution to the environment, no puncture, easy repair and good adhesion to concrete,
stone, metal and other materials substrates.
∎Typical Applications
1.Sealing of expansion and settlement joint of house building, plaza, road, airport runway, anti- all, bridges and tunnels,
building doors and windows etc
2.Sealing of upstream face crack of drainage pipeline, drains, reservoirs, sewage pipes, tanks, silos etc
3.Sealing of through holes on various wall and at floor concrete
4.Sealing of joints of prefab, side fascia, stone and color steel plate, epoxy floor etc
Excellent for moving joints in vertical applications. n Suitable for use between similar as well as dissimilar materials. n Typical applications include joints in concrete panel and wall systems, around window and door frames, reglets, flashing, common roofing detail applications, etc. n Exceptional sealant choice for high-rise and facade applications where high movement capability is required. n An effective sealant for use in Exterior Insulation Finish Systems (EIFS)
