RESIN COMPARISON MATRIX

Selecting the Right Powder Resin for Operational Conditions

Different powder resin systems excel in different environments. Epoxy powders provide superior chemical and corrosion resistance but chalk rapidly under outdoor sunlight. TGIC polyesters resist UV degradation but have lower resistance to harsh solvents.

Powder Chemistry	Outdoor UV Stability	Chemical / Solvent Proof	Impact & Flexibility	Primary Application
Standard TGIC Polyester	Excellent • Zero chalking	Good • Resists fuel, grease	Very Good (160 in-lb)	Exterior turnstiles, telecom housings
Pure Epoxy	Poor • Chalks under UV	Outstanding • Acid/Base proof	Good • High surface hardness	Sub-chassis, battery boxes, industrial machinery
Epoxy-Polyester Hybrid	Moderate • Indoor only	Very Good	Excellent	Avionics chassis, server racks, medical gear

Frequently Asked Engineering Questions

Detailed answers regarding our Plainville facility capabilities, material certifications, testing protocols, and defense contract compliance.

Q: How does Fabtron prevent outgassing on welded assemblies during powder coating?

Trapped air or porosity inside weld seams expands inside the 400°F cure oven, creating pinholes and craters. We utilize specialized outgassing-forgiving (OGF) powder formulations and perform pre-bake thermal cycles on heavy weldments to exhaust all trapped gases before applying the topcoat.
