TD SAND and TD SEAL HT COATINGS

Tru-Design Coating Products

TD Sand is a high-build coating designed to fill layer lines, surface imperfections, seams, and other irregularities in 3D-printed parts and tooling, creating a smooth, uniform surface ready for final finishing. TD Seal RT is our lower-temperature finishing coating engineered to seal the surface, provide vacuum integrity, and create a durable finish that can be sanded and buffed to a Class A surface. For applications requiring higher operating temperatures, TD Seal HT provides the same critical sealing and finishing capabilities in a higher-temperature formulation, delivering vacuum integrity and a high-quality finished surface for demanding tooling applications. Together, TD Sand, TD Seal RT, and TD Seal HT provide a complete finishing system for transforming rough 3D-printed surfaces into smooth, durable, production-ready parts and tooling. Tru-Design coatings are formulated for excellent adhesion to a wide range of thermoplastic and thermoset additive manufacturing materials.

High-viscosity TD Coat RT is designed to fill major surface flaws, voids, seams, and other imperfections commonly found in large-format 3D-printed parts and tooling. Its high-build formulation allows substantial defects to be filled and the surface brought back to the desired geometry without having to machine deeply into the underlying printed substrate. Once cured, TD Coat RT is easily machined, shaped, and finished, providing a significant advantage over machining many carbon-fiber-reinforced and other additive manufacturing materials directly. This can reduce machining time, tooling wear, and finishing labor while providing a smooth, dimensionally accurate surface ready for subsequent finishing operations.
