HC-604 Polyether Amine Curing Agent for Carbon-Based Tile Adhesives
HC-604 is a polyether amine modified curing agent with a long working period at ambient temperature. Its cured products show excellent toughness and bond strength — a natural fit for carbon-based (epoxy) tile adhesives, epoxy coatings and general adhesives.

Product overview
Engineered for its duty
Large-format tile and ventilated facade systems push adhesives hard: long open times for placement, permanent bond strength, and flexibility to survive thermal cycling. HC-604 provides the long ambient pot life applicators need, then cures to a tough, tenacious network that grips dense, low-porosity substrates.
Its low viscosity also makes it easy to formulate — whether as the curing agent in two-component tile adhesives or as a flexibilising co-curing agent in epoxy coating systems.
Key benefits
Why formulators specify it
- Long ambient working period
Extended placement window for large-format tiling. - Excellent toughness
Absorbs thermal movement and shock. - Strong bond performance
Reliable adhesion to dense and smooth substrates. - Low viscosity
Easy mixing, pumping and formulation work.
Applications
Where it is used
- Carbon-based (epoxy) tile adhesives
- Epoxy coating systems
- Structural and assembly adhesives
- Bonding of stone, tile, concrete and metal

Handling & safety
Application and storage
Application
Apply at 5 – 35 °C with dry substrates. Allow full cure before water exposure or grouting over bonded areas.
Pre-test a small sample against your resin batch and project conditions before full-scale use.
Storage
Store sealed in the original container in a cool, dry, well-ventilated area away from ignition sources. Shelf life: 12 months.
Packaging
20 kg and 200 kg net steel drums.
Safety
Amine products may cause skin sensitisation. Wear gloves and eye protection; wash skin contact immediately with plenty of water.
