Product Description

Sinaflex ^®-221B is a one-component, moisture-curable, polyurethane-based, elasto- meric adhesive sealant. It is a fast curing, non-sag system. After curing, it provides a permanently elastic bond to fasten materials with different coefficients of expansion.

Advantages

l Good Adhesion to a wide range of substrates.

l Cures rapidly to a permanently elastic consistency with excellent cut and tear resistance.

l Low odor, non-staining.

l Surface paintable with water, oil, and rubber based coatings.

l Non-Corrosive.

l Provides shock resistance and vibration damping.

l Exhibits high recovery (> 90%), making it ideal for sealing dynamically moving joints.

l Weather resistant.

l Resistant to road salts.
