Range of high performance epoxy curing agents
Ark manufactures, supplies and export a wide range of Specialty Epoxy Curing Agents.
Epoxy systems for various industries, are born from a mixture of different ingredients and a convergence of organic, inorganic, polymer and surface chemistry technologies. We endeavor to realize technical innovations to develop highly functional environment-friendly epoxy hardeners for specialized applications.
Top & Floor Coat Epoxies
We offer easy-to-use, toughened, resilient, two-part specialty epoxies designed to make structural bonds that absorb the stresses of extraordinary expansion, contraction, shock, and vibration. These epoxies have excellent adhesive properties and are engineered to grip tenaciously to metals, plastics, glass, masonry, fiberglass, and wet and difficult to bond woods.
