Paint and Coating Resins & Polymers

Reactive siloxane telechelic and macromeric siloxanes with their intrinsic physical properties and control of structure are now able to extend the range of performance for both urethane- and silicone-based positive tactile interaction coatings.

Using one hundred percent-reactive methylene malonate monomers, difunctionals, multifunctionals and prepolymers, manufacturers of paints, coatings and other products can dial in a wide range of properties to produce a variety of high-performing polymer products that cure rapidly at low or ambient temperatures.

In response to the demand for high performance and biobased polyols for coatings systems, Emery Oleochemicals has launched a family of new azelaic acid-based polyester polyols specifically intended for the C.A.S.E. polyurethane market segments with particular emphasis on coatings applications as discussed in this article.

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.

This novel water-based epoxy system, which offers comparable performance to traditional solventborne epoxy/polyamide systems, can also be applied on civil engineering concrete substrates, and has a lower applied cost.

By using these novel reactive silicones, formulators can develop more-durable solutions that enable customers to reduce system costs by extending the interval between recoating, and by keeping their tanks, pipelines, ships and other assets in service with less downtime.

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.

This study utilized multiple hardness and tack testing procedures in order to fully understand the hardness profile of architectural paints.

Cardura E10P glycidyl ester enables the easy production of high-performance, solvent-free waterborne acrylic polyol dispersions.

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.
