& Surfynol(R) MD-30 Molecular Defoamer Products Foam - Micro or
Macro - Doesn't Stand a Chance Against Dynamic Duo LEHIGH VALLEY,
Pa., Oct. 28 /PRNewswire-FirstCall/ -- Two molecular defoaming
products based on Gemini surfactant technology developed by Air
Products (NYSE:APD) for use in a broad array of applications are
providing formulators with the way to achieve a flat, smooth,
defect-free coating. Surfynol(R) MD-20 and Surfynol(R) MD-30
defoaming agents together present formulators with an answer to the
challenges presented by microfoam and macrofoam in their finished
product. These two Surfynol defoamer products are being featured by
Air Products this week at the International Coatings Expo being
held October 27-29 at McCormick Place North in Chicago, Ill. "In
the formulation process microfoam entrained in the system, and the
macrofoam appearing on the surface, can create craters, pin hole or
fish-eye defects in a surface coating," said Mark Sutovich,
marketing manager-Graphic Arts for Air Products. "Foam presents
unique challenges and undesirable coating defects if not addressed
in the formulation stage. MD-20 and MD-30 work in tandem to knock
down and knock out both micro and macrofoam. There are definite
synergies between these two products which are attractive to the
customer." Specifically, Surfynol MD-20 defoamer combats microfoam,
while Surfynol MD-30 defoamer's expertise is addressing macrofoam.
The two products are molecular defoamers that are surface active
and break foam at the molecular level by attacking the different
mechanisms of foam stabilization. Both Surfynol MD-20 and MD-30
defoamers are silicone and hydrophobic silica-free. "Conventional
defoamers utilize incompatibility to attempt to control foam, but
this creates surface issues and sets the stage for a coating with
defects. It creates a cycle where formulators must add other
surface-active components to eliminate the surface defects created
by conventional defoamers. Molecular defoamers like MD-20 and MD-30
utilize surface activity at a molecular level to allow for
defect-free foam control. They allow formulators to reduce overall
additive levels and break that cycle by working in a complementary
fashion," said Sutovich. Surfynol MD-20 and MD-30 defoamers are
multi-functional products that have other performance attributes
beyond just knockdown foam control. The pair, both in clear liquid
form, exhibit high marks in other important areas such as defoamer
longevity, wetting defect reduction, ease of handling, and also
have wide compounding latitude. These multifunctional defoamers
have a long list of potential waterborne system applications. These
many uses include: coatings for automotive, OEM and DIY wood,
industrial maintenance, metal and paper, and architectural
coatings; graphic arts for printing inks, overprint varnishes and
fountain solutions; adhesives, dye and pigment synthesis, pigment
grinding, oil and gas processing, cleaning products, semiconductor
cleaning and processing, metalworking fluids, cements, mortars and
grouts, and personal care. To view the full text of this
