    ACST8506 Butyl Sealant a non-cured sealant based on butyl rubber . It is highly elastic, low permeability, non-smelling and resistant to weather and time. It has excellent adhesion on metal and other materials. Its excellent adhesion provides excellent use of waterproof, air-proof, and temperature resistant. It is highly versatile and has been widely used in construction sealing, especially steel structures and roofing constructions.
    1、Feature

    1. Butyl sealant is a non-cured sealant, provides excellent performance while the steel panel at low and high temperature. Other sealant (such as Silicone rubber)can not do that the same.
    2. Butyl sealant is the neutral sealant, it do not corrode the steel panel, and can protect the seaming part of the panel.
    3. Butyl sealant have the high cost-effective, and the accommodate temperature is between -40℃ to 90℃.

    2、Main Use
    Gap, joints, overlapping area, ventilation area of steel structures. The joints of steel plates is mechanical joints which small gaps will exist, especially the elastic deform might occur after prolong exposure to extreme weather, wind, or other outside forces. Current sealing tape and sealants can not synchronize with the movement of these joints, result in continuous leaking. Butyl sealant can truly seal the joints and make it a “one piece” steel roof.
    3、Applying Method
    1)Make sure the surface is clean and dry
    2)Cut nozzle to desired size, puncture seal inside the nozzle
    3)Load cartridge into the caulking gun and apply
    4)Any adjustment on the surface can be made before the sealant dries.
    5)Apply the product between 5 to 35℃(40 to 95℉)for the best result.
