Similar to QX-311 mirror silicone sealant, this PVC roofing specialsilicone sealant can cure quickly at room temperature and its curing time isonly 12 minutes, which is shorter than that of the QX-311 sealant. The tensileand shear strength are 1.03 and 1.05 Mpa respectively, which are smaller than those of theQX-311.

If the seamshifts after curing, the displacement is allowed to be 2 times the length ofthe original seam, ensuring perfect sealing at the adhesive position. Notably,this PVC roofing special silicone sealant will release a small amount of gasduring curing, which will cause damage on human body. So the workingenvironment should be well ventilated. It should also be kept away from eyesand other sensitive parts to prevent accidents.
