1、What is the shelf
These curing agents usually have a shelf - life of about 12 to 18 months when stored under proper conditions. They are sensitive to moisture and high temperatures, so it is essential to keep them in a cool, dry place.

Performance Dependence on Curing Agents The choice of curing agent is critical to the performance of epoxy colored sand. Different curing agent types suit different application scenarios.
What is Epoxy Color Sand Curing Agent?
An epoxy color sand curing agent is a specialized additive for epoxy resin coatings, primarily designed to enhance durability, wear resistance, and aesthetics. Typically in liquid form, it must be thoroughly mixed with epoxy resin to initiate a chemical reaction that solidifies the coating.

HF-3175 is a polyamide epoxy curing agent. Low viscosity and long operating time. Excellent adhesion. Can be used in humid environments.
As a widely used material in construction, decoration, and industrial fields, the stability and quality assurance of epoxy colored sand are critical. The curing agent, an indispensable component of epoxy colored sand, directly impacts the service life and performance of the entire system. This article explores the storage duration of epoxy colored sand curing agents and analyzes the main factors affecting their shelf life.
I. Composition and Function of Epoxy Colored Sand Curing Agents
Epoxy colored sand curing agents are mixtures of various chemical substances that promote cross-linking reactions between epoxy resins and curing agents, forming hard and stable coatings. These curing agents typically consist of active diluents, hardeners, accelerators, and other components, which collectively ensure the physical and chemical properties of the cured epoxy colored sand.
II. Storage Conditions for Curing Agents
Effective storage is key to preserving the performance of curing agents. Ideal storage environments include temperature control, humidity management, and light protection.
- Temperature Conditions: Curing agents decompose easily at high temperatures. Storage should maintain low temperatures, with a recommended range of 0°C to 50°C to prevent thermal degradation.
- Humidity Control: High humidity causes curing agents to absorb moisture, reducing their effectiveness. Store them in dry conditions with relative humidity (RH) below 60%.
- Light Protection: Light accelerates photooxidation, reducing stability and lifespan. Store curing agents in opaque containers or use light-shielding materials.
III. Factors Affecting Shelf Life
- Formulation Components: The ratio of active diluents to hardeners influences shelf life. Curing agents with higher active diluent content generally last longer, while those with more hardeners are more susceptible to environmental degradation.
- Storage Conditions: Besides temperature, humidity, and light, factors like packaging seal integrity and container cleanliness also impact shelf life.
- Additive Effects: Additives such as antioxidants or UV absorbers may improve stability but could also alter shelf life depending on their formulation.
IV. Practical Case Analysis
For example, Model A epoxy colored sand curing agent from a company has a 12-month shelf life under standard conditions (25°C, 50% RH). under extreme conditions (40°C, 90% RH), its shelf life reduces to 6 months. This case highlights how environmental factors and formulation interact to affect durability.
V. Conclusions and Recommendations
The shelf life of epoxy colored sand curing agents depends on formulation, storage conditions, and additives. To ensure performance and longevity, enterprises should:
- Strictly control storage environments (temperature, humidity, light).
- Optimize formulations and consider suitable additives.
- Conduct regular inspections and tests to monitor curing agent status.
By addressing these factors, the effective storage time of curing agents can be maximized.
