Sikaflex®-521 UV is an elastic thixotropic multifunctional sealant based
on a polyurethane hybrid polymer, which hardens upon exposure to humidity
atmospheric forming a resistant elastomer.
Sikaflex®-521 UV adheres well to a wide variety of substrates and is suitable
to the creation of elastic sealing and gluing.
Suitable substrates are wood, metals, metal primers and paint systems
(two-component), ceramic and plastic materials.
