ASI 57



ASI 57 Hybrid Sealant & Adhesive is a one-part, polyether product 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. It bonds to a wide array of substrates with aggressive adhesion and resists UV degradation and weathering long-term.

ASI 57 can be used in a variety of environments while remaining easy to apply and tool. It is also able to withstand moisture before complete cure which makes it ideal for damp and wet environments. ASI 57 is 100% solids and has a very ow odor which makes it ideal for confined or occupied work spaces. ASI 57 is ideal for most industrial and construction applications because of its broad adhesion profile, characteristics & properties.

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.
