| abstract |
The present invention discloses a one part, snap curing, acrylic-based composition with long worklife at room temperature. The composition cures in less than 60 seconds at temperatures below 120° C. and provides a suitable worklife of 3 days at room temperature. The composition comprise of a radical initiator with a ten hour half life, 10 hr T 1/2 , equal to or less than 80° C., (meth)acrylate or vinylene-containing base oligomers and at least one additional (meth)acrylate monomer to dilute the base oligomers. Additional ingredients, such as non-reactive chemical compounds, thixotropic agents, pigments, and fillers may be added as desired. A further embodiment of the invention is a method of using the composition with an electronic device. |
