ASI 57



ASI 57 Hybrid Class 50 Hybrid Sealant and Adhesive is a one-part, low odor, no-sag polyether sealant that uses ASI’s innovative hybrid technology to produce a material that is ideal for a wide range of applications where a long-term, durable seal or bond is required. Not only does it aggressively bond to a wide variety of substrates, it reaches 50% joint moveability!

AS 57 will not shrink, is 100% solids and free of isocyanates and solvents, which unlike many solvent based adhesives, makes it easy and consistent to dispense/tool at a variety of temperatures. ASI 57 offers excellent resistance to UV and yellowing for long term performance. It can be applied in damp and wet environments, which makes it’s immediately rain ready and mold and mildew resistant. ASI 57 is for most industrial and construction applications because of it’s broad adhesion profile, characteristics and properties. It can be painted with most consumer and industrial latex paints.

Strength will start to develop immediately and continue increasing for 7 days after application. ASI recommends testing strength and adhesion on the 7th day. ASI 57 suggested application temperature range: 32°F to 150°F. ASI 57 can be applied lower than 32°F. However, it will slow down curing. In general lower temperature & humidity will slow skin and cure times.
