Very similar in properties to the popular 3M 4000UV Adhesive Sealant, Hybrid Sealant 730 is a general purpose clear adhesive/sealant with excellent UV resistance.
It is a one-part, hybrid adhesive/sealant that cures to form a firm, rubbery, waterproof seal.
It is resistant to weathering, saltwater, and stresses caused by joint movement and temperature changes.
It remains flexible and seals between mechanically fastened joints on wood, fiberglass, various metals and most plastics.
Its very high flexibility (low Shore A Hardness) makes 730 good for bonding materials with different coefficients of thermal expansion.
A truly UV stable product, its superior UV resistant properties makes this an ideal above the waterline adhesive sealant.
Unlike polyurethanes, hybrid sealants will not yellow, or leave black streaks from portlights running down your hull.
Unlike the popular 5200, 3M Hybrid Sealant 730 is removable.
This makes it ideal for use in applications requiring periodic maintenance, re-bedding, relocation, or future modification.
