Methylidene malonate was extensively tested for biocompability and adhesive properties in topical and internal applications.  

It has many advantages over current adhesives:

Customizable polymer formulations can optimize adhesive to address specific unmet clinical needs

Main degradation by-products[1] via hydrolysis generate two safe byproducts, ethanol and glycolic acid.

Adheres to wet tissues

Achieves a strong bond while remaining very flexible and elastic

Generates minimal heat during polymerization
