Emerald Kalama Chemical Unveils K-FLEX® 500P, a Low VOC Coalescent for Architectural Coatings

Published on 2013-04-05. Author : SpecialChem

CUYAHOGA FALLS, OH -- Emerald Kalama Chemical, a business group of Emerald Performance Materials, has announced its newest product in the growing K-FLEX product platform. K-FLEX® 500P is the lowest VOC coalescent in the product line, designed for architectural coatings where very low VOCs, excellent gloss, scrub, block, and freeze-thaw characteristics are all desired features. Kalama K-FLEX dibenzoate esters are highly effective, low VOC, non-phthalate, non-alkyl phenol ethoxylate (APE-free) and are compatible with a wide range of polymers, including acrylic, styrene acrylic, vinyl acetate (PVA), vinyl acetate-ethylene (VAE), and polyvinyl chloride (PVC) systems.

"Emerald Kalama Chemical has made a major investment over the last several years to develop new coalescents for coatings applications that will meet the challenges the industry has faced to meet the lower VOC requirements, while improving-not sacrificing-performance," said Shamsi Gravel, Emerald Kalama's Product Line Manager for The Americas. "Historically, the many efforts to reduce VOCs through the use of softer polymers and/or low-VOC coalescents have come at the expense of sacrificing performance in other areas, such as hardness, blocking and dirt pick up. Our latest K-FLEX low-VOC products have addressed such concerns and have been shown to improve certain performance features, such as scrub resistance and gloss retention, when tested in several polymer systems representing different compositions and Tgs."

K-FLEX 500P has a VOC level of 0.9% when tested according to ASTM D-2369. The new product also exhibits equivalent efficiency to traditional high-VOC coalescents, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TMPDMIB), so it can be used at similar levels in the paint formulation. Therefore the impact of K-FLEX 500P on VOCs in the final coating at a typical 1.5 wt.% use level-approximately 2 grams per liter (ASTM D-6886)-is extremely low. In coatings applications, the use of K-FLEX 500P results in improved freeze/thaw, wet edge (flat), scrub resistance, and excellent gloss retention while still offering comparable blocking resistance (semi-gloss).

The components of K-FLEX 500P are listed under FDA 21CFR175.105, 21CFR176.170 and 21CFR176.180 and are REACH-registered in the EU. The product is also classified as non-hazardous under OSHA. In addition, unlike some other plasticizers, it is specially formulated so that it does not bear a "dangerous for the environment" pictogram on the label under the newest European CLP Regulation (EC) 1272/2008.

Emerald Kalama Chemical also produces sodium and potassium benzoate, benzoic acid and intermediates, and specialty flavor and fragrance ingredients, which the company sells globally through its distribution partners. The business has manufacturing operations in Kalama, WA and in Rotterdam, The Netherlands. Emerald Kalama Chemical products are used in a range of applications from beverage preservatives to personal care and household products, as well as industrial applications.
