Adhering to Difficult Substrates with Silicone Adhesives

Substrates with reactive groups available for bonding make chemical bonding easier to achieve, while substrates with nothing to react to make adhesion difficult.
October 1, 2005
Adhesive technology is equal parts chemistry and "black magic." The sheer number of available substrates makes it nearly impossible to test each adhesive on every type. However, by conducting tests on a selection of novel, or difficult-to-adhere-to, substrates, we can make inferences that may help narrow the choice of adhesives.
