H.B. Fuller Co. has signed an agreement to sell its surfactants, thickeners and dispersants business to Tiarco LLC, a wholly owned subsidiary of Textile Rubber and Chemical Co. Inc.
Safety and performance take center stage in Carpenter Co.'s line of nonionic surfactants, which provide a range of EO/PO block copolymers that serve a wide variety of markets where defoaming, wetting and emulsifying are critical.
Lindsay Doyle's lube emulsion and her customer's acrylic dispersion both crashed and separated like curdled milk. What had caused both systems to crash, and how were the causes related?
Maxemul reactive surfactants act as efficient emulsifiers providing colloidal stability and are chemically bonded to the polymer particles during free radical polymerization. The enhanced stability and mitigation of surfactant leaching during and after film forming significantly improve water resistance and barrier properties of the latex binder as a replacement of conventional surfactants.
Stepan Co., through a subsidiary in Mexico, has reached an agreement with BASF Mexicana S.A. DE C.V. to acquire its surfactant production facility in Ecatepec, Mexico, and a portion of its associated surfactants business.
By understanding how additive performance can be affected by formulation change, formulators can identify potential problems and work with their suppliers to find answers faster.
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.
As part of a plan to expand its activities and increase its capacity to serve clients in the region, Oxiteno appointed Timothy Earl Madden as COO of Oxiteno USA.
