Submit Your Lamination Questions

If you think blowing air on a laminate helps the resin cure faster, you should attend The Validity of Myths About the Lamination Process, an education session at C+P 2009. “That’s one of the most common myths,” says John Hewitt, technical service manager at Interplastic and one of the session’s presenters. “It does air dry, but it’s not curing. It’s not a paint. If you dry too much off on a thin laminate, you can actually cause undercure, especially now that the industry has moved to a low monomer product.”

Hewitt and two other presenters will answer questions you have about the lamination manufacturing process. “Many people are doing things they think are helping their process, but they’re actually hurting their processes,” Hewitt says. Here are some of the myths Hewitt says he hears regularly:

Myth 1:The higher the peroxide, the better the resin cure.

Myth 2: After a long time, the secondary bond to an ortho or Iso resin is much better than to a DCPD resin.

Myth 3: The exotherm of skincoat laminate should be higher than that of the bulk resin.

Myth 4: Shrinkage of the resin is the major factor in prerelease

Myth 5: Thix index is a good indicator of resistance to drainage.

Myth 6: Covering a laminate will slow down the cure rate

The panel will address these common beliefs and answer questions from attendees. To submit your questions ahead of time, email jhewittresinguy@hotmail.com.
