This work demonstrated that through the use of a single surfactant, Calfax 16 L-35, a simple emulsion polymerization process can generate 45% hydrophobic latex with particle size in the range of 100-150 nm at a conversion rate of >98% at the end of a 4-hr reaction, without a chase process.
The combination of a high-Tg, hydrophobic, high-MW alkyd with the proper surfactants and levels can produce a highly corrosion-resistant DTM alkyd emulsion when formulated with select pigment dispersants.
AgriEsters (methyl soyate, palm and coconut esters) are a new, low-cost alternative that can help emulsify old solvent-based resins (bead acrylics, oil-based alkyds and polyterpenes), giving formulators new alternatives.
Nychem™ 1561X604 is a new nitrile latex emulsion designed to optimize strength, abrasion resistance, chemical resistance and other performance characteristics
The knowledge of the role of APE-free surfactant system on the number of particles through nucleation and growth stages was shown to be important for developing latexes with high solid contents.
After completing installation of a new R&D pilot plant in December, Emerald Polymer Additives and Nitriles, a business group of Emerald Performance Materials, appointed Brian Corrigan as Nitriles Account Manager to accelerate growth of the group’s Nychem™ latex emulsions line.
