New Advances in Epoxy Protective Coatings

New Advances in Epoxy Protective Coatings
Available for download

Epoxy coatings are a mainstay of the protective and marine coatings markets. Used as intermediate coats over inorganic and organic zinc rich primers or used as direct-to-metal primers in coating systems, epoxy coatings are widely recognized for their versatility and the excellent corrosion resistance they provide. One drawback to current epoxy coating technology is that it requires separate packaging for the epoxy resins and the amide or amine hardeners because the chemical reaction between these materials causing the applied film to cure to a dry state would also cause the bulk material to gel if packaged together (pot life).

Epoxy coatings are a mainstay of the protective and marine coatings markets. Used as intermediate coats over inorganic and organic zinc rich primers or used as direct-to-metal primers in coating systems, epoxy coatings are widely recognized for their versatility and the excellent corrosion resistance they provide. One drawback to current epoxy coating technology is that it requires separate packaging for the epoxy resins and the amide or amine hardeners because the chemical reaction between these materials causing the applied film to cure to a dry state would also cause the bulk material to gel if packaged together (pot life). Until now, single-pack epoxy coatings have been based on epoxy-ester resins, which are not as robust as true amine-cured epoxy coatings or have been based on epoxy resins and latent hardeners, which require a bake cure and therefore are not practical for most protective and marine coating applications. This paper will review the features and benefits of a new epoxy coating technology that allows for true epoxy-amine curing in a single-pack product. Performance versus traditional two-component epoxy products will be compared, and environmental and convenience benefits of single-pack versus two-component packaging will be discussed.

Improving the Performance of Epoxy-Polysiloxane Coatings

Product Number: 41215-907-SG
Author: Dean Kondos, Vikram Kumar, Kujtim Bizati, Christian Geismann, Martin Wusik
Publication Date: 2015
$20.00

A new patent-pending resin technology incorporated into the epoxy/polysiloxane part A portion of a two-component coating system, using an amino-silane curing agent, has shown significant improvements in flexibility, gloss and color retention. Corrosion resistance and adhesion to non-sandblasted metal substrates have also shown improvements. The new resin technology may be considered for low-VOC and HAPs coating systems.

Improvement of Weather Resistance for Epoxy Based Coatings on Marine Structures

Product Number: 51216-008-SG
Author: Sang-Moon Shin, Chung-Seo Park, Seung-Gon Choo, Sang-Sik Park, Kyoung-Sub Hwang
Publication Date: 2016

Epoxy-based coating used in the ships and marine structures can be quickly degraded after only a short period of exterior exposure. The weathering defects such as discoloration, chalking and gloss reduction are originated from a photo-oxidation of aromatic group in the epoxy resin under the UV light. Weather resistance coatings such as polyurethane and polysiloxane require more work due to the short over-coating interval and low compatibility with primer coating layers.
