These resins combine the same wide range of properties of the thermoplaste grades with the excelent solvent resistance, flexibi- ty, impact resistance, and high hardness of a crosslinked system. USER'S GUIDE TO THIS BOOKLET ‘This booklet has been designed 10 ‘id you, the user, in selecting the appropriate Paraioid thermosetting resins to mest your needs in formu- lating conventional solids and high solids coatings. It is organized for your convenience in the following manner: Individual Grades of Paraloid Thermosetting Resins provides a ‘concise description for each conven tional-solids and high-solids Paraloid thermosetting resin available. ‘Typical Physical Properties is ¢ table that summarizes the important Physical properties of each resin grade. Applications and Desired Prop- erties are tables that permit you to rapidly identify each resin which offers those features that are of par- ticular interest to you. It also pin- points the recommended resins for the end uses you have in mind. Compatibility and Solvent Tolerance are tables thai provide useful information regarding the abiity of each Paraloid resin to be used with a variety of other resins and solvents. Formulations and Application Properties provides detailed infor- mation about formulating proce- dures, starting point formulations, and the performance properties of coatings based on Paraloid ther- ‘mosetting resins. ‘Additional Information This bookeet nas been prepared as ‘an introduction and guide to the variety and usefuiness of Paraloid thermosetting resins for convertion- al-solds. and high-solids coatings. ‘Adcitional information can be obiained from your local technical representative, or by writing directly to Paraloid® Resins, Performance Polymers, Rohm and Haas Company, 100 Independence Mall West, Philadelphia, Pennsylvania, 19106.

Lranehorey Raa Paraloid AT-746 Paraloid AT-746 is a thermosetting acrylic polymer supplied at 50% solids in xylene. When crosslinked vith a nitrogen resin, it cues al stan- ard baking temperatures to an extremely hard, glossy film which possesses. superior resistance 10 soap, detergents, and staining. By virtue ofits high degree of crossink- ing, it develops excellent solvent resistance, print resistance, and resistance to deformation al ekevated temperatures. Gloss retention and color retention are also excellent. Paraloid AT-746 exhibits a wide range of compatibiity with other fim formers and plasticizers, a factor that provides considerable formulat- ing latitude, ‘The use of Paraloid AT-746 allows the formulator to select the melamine resin type and level that wil deiver the desired balance of properties, Paraloid AT-63 Paralcid AT-63 is a thermosetting ‘acrylic resin that is crosslinked with a nitrogen resin to produce baking coatings that ae fast-curing and possess medium hardness, good adhesion, excellent flexiilty, good ‘overbake resistance, high gloss, and exterior durability. It is suppied at 180% solids in xylene. Paraloid WR-97 Paraloid WR-97 is a thermosetting acrylic resin that is both water and solvent reducible. It has excellent compatibility with a wide variety of urea and melamine crosslinking resins, thermosetting acrylic ernul- sions, and aqueous colloidal disper- sions. It's used for general purpose Sprayable high-gloss industrial fin ishes and as a universal pigment dispersion medium. Paraloid WR-97 resin is supplied at 70% solids in a mixture of iso- propanol and butyl Cellosoive™. Paraloid AT-400/Paraloid AT-410 Paraloid AT-400 and Paraloid AT-410 are thermosetting acrylic resins supplied in methyl n-amyl ketone. They react with artino- plasts to provide coatings that cure at low temperature (250°F), without the use of an external catalyst, and have an excelent balance of hard- ness, gloss, flexbilty, and resis- tance properties. The higher aopication solids allow the user to spray coatings without the sag problems associated with many high solids polyesters, Enamels based on Paraloid AT-410 resin have higher gloss with better stain and solvent resistance than those based on Paraloid AT-400. However, Paraloid AT-400 based enamels have good exterior durabli- ty while Paraloic AT-410 ones do not. Addition of Paraloid AT-400 and Paraloid AT-410 wil also improve the Performance of polyester polyol crossiinked systems.2 Paraloid AT-76 Paraloid AT-76 is a thermosetting acrylic intermediate designed to crosslink with epoxy resins to give aan outstanding balance of fabrica- tion, dry heat, and processing resis- tance for metal-decorating applica- tions. It provides excellent color, high gloss, and retention of pertor- mance properties after high-tem- perature overbakes, Paraioid AT-76 resin is supplied at 41% solids in a mixture of Aromatic, 160 and butyl Cellosotve. Paraloid AT-81/Paraloid AT-147 Paraloid AF81 is a thermosetting acrylic intermediate designed to be crossinked with epoxy resins. It is supplied at 55% solids in a mixture of ‘Aromatic 150 and butyl Celosolve. This solvent systam makes Paraioid AT-B1 resin suitable for rol coat applications and for metal-decorat- ing fishes, Paraloid AT-147 is similar to Paraloid AT81 but it is supplied in buty! Callosolve alone, Pardloid AT-81 is generally used in combination with Paraloid AT-85, a softer acrylic resin intermediate, Paraloid AT-85/Paraloid AT-148 Paralod AT-85 is a thetmosatiing aaryic intermediate designed to be crossinked with epoxy resins for pro- ducing metal-decorating finishes. tt is softer than Paratoid AFS1 resin and its aso supplied at 85% solids in Aromatic 150 and butyl Celosove. Paraloid AT-148 is similar to Paraloid ‘AT-85 but supplied in butyl Celosolve alone. Paraloid AT-SLO Paraloid AT-9LO is a thermosetting acrylic resin designed to crosslink with epoxy resins.

A polymeric meamine such as Oymel 825 should be used to achieve Uncatalyzed oures at 250°F, Where maxmum solids are desired a monomeric melamine such as Oymel 308 should be used, but the formulation wil requre an external catalyst Polyester Modification In addition, Paraloid AT-400 and Paraloid AT-410 may be used to uparede the performance of poly- ‘ester polyois in melamine crossinked systems. ‘Typical starting point formulations based on these products for con- ventional spray applications are pre- sented in Tables 13 and 14. The ‘small amounts of solvent required to reduce to spray viscosity help to keep the cost competitive with con- ventional ename's. Stability Enamels based on Paraloid AT-400 and Paraloid AT-410 resins exhibit ‘excelent viscosity stability. Fim properties of aged enamels formulat- ‘ed with Cymel 325 or Cymel 303 have been found to be comparable to those of freshly prepared samples. ‘Spray Applications Enamels based on Paraloid AT-400 and Parclod AT-410 resins exhibit excellent conventional spray proper- ties with outstanding sag and crater resistance. The application solids can be formulated at greater than 50% solids. (Formulations AT-400-1, ‘AP-400-2, AT410-1 and AT-410-2) They also exhibit an overspray with lower tack than high solids poly- esters to alow for easier cleanup. 7PARALOID® THERMOSETTING ACRYLIC RESINS Physical Properties, Features, and Formulating Guidelines TABLE 13 CONVENTIONAL SPRAY WHITE BAKING ENAMELS Formulation AT-400-1 Formulation AT-400-2 Materials Pounds Gallons Pounds Gallons Sand Mill Grind (15 Minutes}: T-Pure R-902 339.0 9.90 351.0 10.25 Paraloid AT-400 (75% nonvolaties) 198.9 23.29 205.9 2414 -Butenol 98.4 1465 1287 19.15 Methy|n-amy ketone Pika 6.16 164 2.82 Sand - 700 parts by weight Total 678.0 54.00 702.0 55.93 % Solids 72.0 72.0 Storage Enamet: Sand Grind 678.0 54.00 702.0 55.93 Paraloid AT-400 2185 25.28 223.1 26.18 Cymel 325 1295 1392 — — Cymel 303 — = 1073 10.78 Methyl n-amy ketone 228 337 22.0 8.25 PM acetate 296 367 257 3.19 Dow 578 08 ont a8 ott Catalyst 4040 (40% pTSA) = = 54 og?

Both are used in combination with {an epoxy resin for metal decorating. ‘The degree of crosslinking can be varied by selecting the appropriate aoryic/epaxy resin rallo to obtan the desired balance of flexibility and resistance properties. Formulation AT-85-1 is a white bak- ing enamel using Paraloid AT-85 resin as the sole acryic binder. This eyster gives @ tough metal-deco- rating coating with the highest hot stacking resistance, impact resis- tance, and resistance to water sott ening (S28 Table 19} Formulation AT-85-2, another white baking enamel based on Paraloid AT-85 resin, has a higher acrylic to epoxy resin ratio and offers more resistance to severe fabrication and dry heat (see Table 19). Formulation A-85-3 utlizes both Paralcid AT-85 and Paraloid AT-81 resins and provides a balanced for- ‘mulation with resistance to severe fabrication and cry heat at the sight ‘expense of hot stacking resistance, water sottening resistance, and hardness (see Table 20).
