Two-part curable compositions capable of demonstrating substantially no phase separation at room temperature over time and improved adhesion strength retention at elevated temperature conditions.

Two part curable compositions

Photocurable adhesive compositions are provided herein, which have a balance of fast curing properties and strength development and retention over time after exposure to accelerated ageing conditions.

Photocurable adhesive compositions

A curable composition, includes a diluent, an epoxy functionalized resin derived from a nutshell oil, an epoxy-rubber copolymer adduct, and a curing agent. There is disclosed a method for making the curable composition, a method of imbuing improved flexibility to a curable composition and a method for improving oily metal adhesion of a curable composition. The method of imbuing improved flexibility to a curable composition includes providing a curable composition, adding an epoxy functionalized resin derived from a nutshell oil and adding a liquid modified hydrocarbon resin derived from a nutshell oil.

Curable compositions

This invention relates to cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, a rubber toughening component, which is substantially clear and colorless and which is substantially free of release agents and anti-oxidants known to impair the fixture speeds and shelf life stability of cyanoacrylate compositions to which they are added. As a result, the inventive rubber cyanoacrylate adhesive compositions demonstrate improved properties, such as fixture speed, strength and shelf life under accelerated aging conditions.

Toughened cyanoacrylate compositions

Cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, an anhydride and a maleimide-, itaconimide-, or nadimide-containing compound, are provided. Cured products of the inventive cyanoacrylate compositions demonstrate improved moisture and/or heat resistance.

Cyanoacrylate compositions

This invention relates to flexible cyanoacrylate-containing compositions, having improved torsion stress resistance particularly when bonded to plastic substrates.
