1300 series

Epoxy-based, one-pack thermosetting inks for metals, metallic coats, and glass where high adhesion and chemical resistance are critical. The one-pack system cures to deliver outstanding film performance on curable substrates.

Key Specifications

Parameter	Details
Ink Type	One-pack thermosetting epoxy inks with special synthetic resins. Contains a catalyst enabling curing at relatively lower temperatures versus conventional epoxies.
Usage	Nameplates, electrical appliances, glass parts, and components made of aluminium, zinc-plated iron, stainless steel, iron, and their coats.
Finish	Gloss finish with good leveling.
Drying Time	Heating required — standard 30 minutes at 150 °C.
Diluent	Add T-1000 (10–15 parts to 100 parts ink) to adjust viscosity.
Adhesion	Strong adhesion to metals, metallic coats, and glass (see ink film test results).
Notes / Guidance	Requires proper curing for best film performance; epoxy films can chalk with moisture, especially outdoors (signboards, direction signs). Store in a dark, cool place with minimal air exposure. Built-in catalyst shortens cure time; if performance drops (aging/exposure), add 1300 catalyst H up to 1% (w/w) after testing. For multi-layer prints, undercolors should cure below 150 °C; final layer at 150 °C to ensure stack adhesion. On glass, printed film may show lower water/moisture resistance than on metals/metal coats.
