DELTA FAST Fast-Drying Clear Epoxy Resin

DELTAFAST is a fast-curing, two-component epoxy system developed for all applications requiring reduced working times, high transparency, and excellent mechanical performance.

Its formulation is completely solvent- and VOC-free, characterized by low viscosity, high transparency and gloss, very low odor, and a reduced tendency to yellow. It also offers excellent chemical and mechanical resistance and good resistance to carbonation.

Thanks to its accelerated formulation, DELTAFAST is particularly suitable for applications requiring faster curing than a traditional epoxy resin. At 25 °C, with a 150 g mass, it has a pot life of approximately 15–20 minutes and a curing time of approximately 20–35 minutes; in thin layers, curing times are 12–24 hours.

Ideal for: embedding small objects, self-leveling castings, resin paintings and artistic creations, mold making, sealing, waterproofing, final polishing treatments, protective coatings and artistic flooring, fiberglass and composite fiber applications, and marine applications.

Mixing ratio

By weight: A:B = 100:50 (2:1)
By volume: A:B = 100:57

To achieve proper mixing, accurately weigh the two components in the same container and mix until obtaining a perfectly homogeneous compound, avoiding the incorporation of excessive air.

Application thickness and temperature

For thick-layer applications, a minimum temperature of 10 °C is recommended, with an indicative maximum thickness of approximately 1–1.5 cm for masses under 1 kg. For coating applications, a minimum temperature of 18 °C is recommended. The substrate must be dry, perfectly clean, and free of friable parts.

DELTAFAST is the Delta Resins solution designed for those seeking transparency, versatility, and faster working times, without compromising the performance of a professional epoxy system.
