Acrylic Powder Brochure - Reichhold

1 Reichhold s parent company, DainipponInk & Chemicals (DIC), is a worldleader in glycidyl methacrylate(GMA) Acrylic resin technology andhas been developing and manufactur-ing Acrylic Powder coating resins forover 20 years. Acrylic resins havebeen used in Powder coatings sincethe 1970 s, and have been steadilygrowing in s FINE-CLAD acrylicresins have three distinct uses in Powder coating applications:1. As Primary Film-Formingresinsin automotive applications such asfull-body clear coats and aluminumwheel coatings, and in decorativecoatings for brass As Crosslinkersfor polyesterresins in matte coatings where theyact as gloss-control agents in applica-tions such as automotive trims, archi-tectural metals, and high-quality As Additivesthat promoteimproved flow and leveling andenhanced stain and chemical resistancein polyester hybrid, polyester TGIC andpolyurethane Powder Acrylics asFilm-Forming ResinsAcrylic powders display excellent filmappearance and clarity in demandingclear coat applications such as auto-motive full-body clear coats.

These powders contain acrylicresins crosslinked with a long-chaindibasic acid such as DodecanedioicAcid (DDDA).FINE-CLAD A-253and A-272areexcellent choices for full-body clearcoat applications requiring scratchand mar resistance, because of theirhigh-oxirane A-254is an excellentcandidate for powders in wheel andbrass hardware applications where itshigh flow properties translate intohigh-DOI (distinctness of image) A-257was engineeredwith dual functions in mind. Its pro-prietary chemistry gives excellentadhesion to aluminum for filiformcorrosion-resistant wheel clears andin pigmented powders, it shows verygood pigment A-270is speciallydesigned for coatings with demandingpigmentation requirements, includinghigh-pigment-load formulas and hard-to-disperse chromatic ( C)EEW (g/eq)

These Acrylic -cured mattepowder coatings work well in applica-tions such as automotive trims, archi-tectural metals, and high-quality has developed four systemsbased on this technology.

4 We refer tothese systems as MULTI-CURE,SUPERDURABLE MULTI-CURE,DUAL COMPONENT andWEATHERABLE Acrylic crosslinkers can cureunique bi-functional polyesters thatcontain both carboxyl and hydroxylgroups (MULTI-CURE and SUPER-DURABLE MULTI-CURE) as well ascarboxylated polyester resins (DUALCOMPONENT and WEATHERABLEHYBRID). In each case, matte finish-es are obtained with attractive fea-tures and excellent mechanical prop-erties. The Acrylic gloss-controlagents, FINE-CLAD A-249-A and A-266 have been designed to reducegloss of polyester Powder coatings,while A-229-30-A helps to raisecured film gloss, when used in combi-nation with either gloss-control adjusting the ratios of gloss-control agent to A-229-30-A.

5 The for-mulator can control gloss without sac-rificing important coating used as crosslinkers for poly-ester resins in matte Powder coatingsdemonstrate no compatibility problems beyond those that would beencountered with other standard Powder Acrylics asAdditivesAcrylic resins are used as additives topromote improved flow and levelingas well as enhanced stain and chemi-cal resistance in polyester hybrid,polyester TGIC, and polyurethanepowder coatings. Unlike standard flowaids, these reactive materials provideimprovements in film properties bycrosslinking into the Powder coatingpolymer backbone. These materialsalso help improve compatibilitybetween batches of two individualpowder coatings by improving each powders crater A-241 contains oxiraneand hydroxyl functionality, and willcrosslink into all thermoset powderchemistries.
