Since 1895, Smooth-On (Macungie, Pa., U.S.) remains a dynamic, family-owned U.S. manufacturer of specialty materials — silicones, epoxies and release agents, etc. — used for a variety of applications across different industries and shipped globally. Smooth-On offers more than 80 years of materials leadership in aerospace, marine and motorsports applications and has custom formulation capabilities. 

From prototyping a lightweight UAV component to laying up high-temperature autoclave tooling, Smooth-On says it delivers every chemistry needed under one trusted roof. The company’s sprayable and brush-on silicones capture intricate details while resisting the aggressive resins and cure cycles demanded by carbon fiber, fiberglass and Kevlar layups. Step directly into production with Free-Form Air HT or EZ-Spray Silicone 20 — products that eliminate pattern-making time and extend mold life, reducing cost per part.

When strength and dimensional stability matter, Smooth-On suggests EpoxAmite laminating epoxies and EpoxAcoat gelcoat systems. These low-viscosity, low-exotherm epoxies wet out reinforcement quickly, cure bubble-free and hold tight tolerances at high service temps. Pair them with Ease Release or Price Driscoll release agents for easy demolding and a showroom-finish surfaces.

Because every program is unique, Smooth-On’s portfolio spans Shore 10A silicones to 90D epoxies, enabling customers to dial in durometer, pot life and high-temp performance. Its hands-on support team, comprising experience material experts, are available to discuss project needs.

Smooth-On has 400,000 square feet of manufacturing space, six U.S. warehouses and 160 global distributors, all aiming to cut lead times and keep critical programs on schedule.
