Professional Two-Part Epoxy Systems for Scale Modeling

Two-part epoxy adhesives provide superior bonding strength, gap-filling capabilities, and extended working time compared to cyanoacrylate instant adhesives, making them essential for structural assemblies, dissimilar material bonding, and applications requiring precise positioning before cure. Our collection of 24 professional epoxy formulas spans multiple cure times from fast-setting 5-minute formulas for quick assembly to slow-cure systems offering extended working time for complex alignments. Each two-part system combines resin and hardener in precise ratios, initiating chemical cross-linking that creates permanent bonds resistant to vibration, impact, and environmental stress across plastic, wood, metal, fiberglass, and composite materials.

Bob Smith Industries: Industry-Standard Epoxy Systems

Bob Smith Industries dominates professional modeling adhesives with eight precision epoxy formulas engineered for specific applications. Their Mid-Cure 5 Minute Epoxy in 4.5 oz. and 9 oz. sizes provides rapid bonding for general assembly work, offering sufficient working time for positioning while achieving handling strength within minutes. The Mid-Cure 15 Minute Epoxy extends working time for complex assemblies requiring careful alignment, perfect for multi-part structural joints and large surface area bonding. BSI's Finish Cure 20 Minute Epoxy in 4.5 oz. and 13 oz. sizes delivers extended open time for intricate work, while their Slow-Cure Epoxy in 4.5 oz. and 9 oz. formulations provides maximum working time for laminating, gap filling, and applications requiring precise positioning before cure initiation.

Deluxe Materials Speed Epoxy and Aero Tech Systems

Deluxe Materials contributes eight specialized epoxy formulas including their Speed Epoxy II series in 4-minute, 20-minute, and 60-minute cure times. The Speed Epoxy II 4 Minute formula in 28g, 71g, and 224g sizes provides rapid bonding for quick assembly operations, while the 20-minute and 60-minute variants offer progressively longer working times for complex structural work. Deluxe Materials' innovative Speed Epoxy II Syringe 28g 4 Minute delivers precise dispensing control, eliminating waste and ensuring accurate resin-to-hardener ratios. Their Aero Tech 25ml and 50ml formulas provide specialized bonding for R/C aircraft construction, offering lightweight, high-strength bonds optimized for balsa, plywood, and composite airframe materials. These formulas resist fuel exposure, vibration, and aerodynamic stress encountered in radio control aviation.

ZAP Z-Poxy and Finishing Resin Systems

ZAP offers eight epoxy products including their Z-Poxy 5 Minute formula in 1 oz. syringe, 4 oz., and 8 oz. sizes for rapid assembly work. The Z-Poxy 15 Minute 4 oz. formula provides extended working time, while their Z-Poxy 30 Minute 8 oz. system delivers maximum positioning time for complex structural assemblies. ZAP's Finishing Resin in 4 oz. and 12 oz. sizes serves dual purposes as both structural adhesive and clear coating system, providing glossy, fuel-proof finishes for R/C aircraft, boat hulls, and display models. The self-leveling formula fills weave in fiberglass cloth, seals wood grain, and creates glass-smooth surfaces ideal for high-performance applications and show-quality finishes.

Application Tools and Mixing Accessories

DU-BRO provides essential Epoxy Brushes for precise application and mixing, featuring disposable bristles that eliminate cleanup while enabling controlled spreading on large surface areas. Proper mixing technique ensures complete resin-hardener integration, critical for achieving maximum bond strength and predictable cure times. Equal parts mixing by volume or weight (depending on manufacturer specifications) activates the chemical cross-linking process, with thorough stirring for 30-60 seconds ensuring homogeneous mixture without air entrapment.

Epoxy Selection Guide and Best Practices

Selecting appropriate cure time depends on assembly complexity and required working time. Fast-setting 5-minute formulas suit simple joints requiring rapid handling strength, while 15-20 minute systems accommodate complex alignments and multi-part assemblies. Slow-cure and 30-60 minute formulas provide maximum working time for laminating, gap filling, and applications requiring extended positioning. Surface preparation through light sanding and solvent cleaning maximizes bond strength, while proper mixing ratios ensure predictable cure characteristics.
