What is debubblizer?
Debubblizer is a surfactant used in the dental industry to remove bubbles from molding plastics. A good casting requires a perfect mold. Bubbles can easily ruin a casting. Dentists often try several debubblizer products before discovering one which suits their needs.
In Modesto, several years ago, I met a debubblizer producer. He recently started his debubblizer business and was enjoying early success. He told me he only had to get a dentist to try his debubblizer, and he had a new customer. On the day we talked, a dentist earlier told him with surprise, "There are no bubbles! This is going to save me a lot of work."
Later, Russman had enough demand to have his product listed and stored by most of the large dental supply companies. A debubblizer surfactant is typically used in the formation of stone casts in molds of alginate, silicone, polysulfur, polysulfide, or rubber base.

How to Use Debubblizer
By breaking the surface tension of material (the full exterior skin of the material), the material, usually gypsum, flows into grooves and voids. Air is able to pass easily out of treated investment. An impression is made. Once the mold is formed, spray debubblizer before pouring gypsum or other die stone. The stone mixture is vibrated on a laboratory vibrator to remove as many bubbles as possible before pouring. While the investment is poured, any bubbles trapped beneath the pour, and against the mold will slip up and out because of the action of the debubblizer. Bubble slip out of the most important part of the casting- the exterior boundaries.
Casts formed in molds treated with debubblizer perform dramatically better than untreated molds. Watch the video below to see how a product called Vacalon hydrosmooth debubblizer improves the final casting. At the end of this short video, a side by side comparison is provided.
