Epoxy Flooring Primer Curing Agent: Overview

Epoxy flooring primer curing agents are critical components that initiate cross-linking reactions with epoxy resins, ensuring adhesion, durability, and chemical resistance. Below is a summary of key properties, types, and applications:

Category	Details
Function	Catalyzes epoxy resin polymerization, forming a rigid, chemically stable coating.
Common Types	– Polyamine – Polyamide – Amine adducts – Phenalkamines – Cycloaliphatic amines
Curing Mechanism	Exothermic reaction; forms irreversible thermosetting bonds.
Key Properties	– Fast/slow cure options – Low viscosity (enhances penetration) – Moisture tolerance – Chemical/abrasion resistance
Mix Ratio	Typically 1:1 to 5:1 (resin:curing agent) – varies by formulation.
Pot Life	20–60 minutes (adjustable with additives).
Curing Time	Touch-dry: 4–12 hrs; Full cure: 24–72 hrs (depends on temperature/humidity).
Applications	– Concrete floor priming – Industrial facilities – Warehouses – Garages – Hospitals
Advantages	– Superior adhesion – Seals porous substrates – High mechanical strength – Solvent-free options available
Limitations	– Sensitive to mixing accuracy – Temperature-dependent performance (ideal: 10–30°C).

Selection Criteria

Substrate Condition: Polyamines for humid environments; amine adducts for fast curing.

Temperature: Cold climates require low-temperature-tolerant agents (e.g., phenalkamines).

Chemical Exposure: Cycloaliphatic amines for acid/alkali resistance.

Safety & Handling

Wear PPE (gloves, goggles).

Ensure ventilation; avoid skin contact (may cause dermatitis).

Store in airtight containers (moisture-sensitive).
