Epoxy Resin Selection Guide
Epoxy Resin is a thermosetting polymer formed from the reaction of Epichlorohydrin and Bisphenol A. It is valued in the chemical industry for its exceptional mechanical strength, chemical resistance, and strong adhesion properties. At RawChemicalMart, we offer grades that serve as direct replacements for major international brands.
Liquid vs. Solid Epoxy: Which do you need?
Epoxy resins are generally classified by their physical state at room temperature and their Epoxide Equivalent Weight (EEW).
1. Liquid Epoxy Resin (LER)
The most widely used type, typically known as "128 Grade" or "E-51".
- Characteristics: Clear, viscous liquid. High purity and low color (APHA < 50).
- Common Grades: NPEL-128, CYD-128, E-44, E-51.
- Applications: Self-leveling epoxy flooring, casting, potting, filament winding, and solvent-free coatings.
2. Solid Epoxy Resin (SER)
These are higher molecular weight resins used primarily in heat-cured applications.
- Characteristics: Yellowish flakes or granules.
- Common Grades: E-12 (604), E-20.
- Applications: Powder coatings, coil coatings, and anti-corrosion primers for steel structures.
Key Industrial Applications
| Industry | Recommended Type | Function |
|---|---|---|
| Construction (Flooring) | Liquid (128) | Provides a seamless, high-gloss, and chemical-resistant surface for warehouses and factories. |
| Paints & Coatings | Solid (E-12) / Liquid | Used in marine paints and metal primers to prevent rust and corrosion. |
| Adhesives | Liquid (128) | Forms high-strength structural bonds for metal, ceramic, and stone. |
| Electronics | Liquid (Electronic Grade) | Encapsulation and potting to protect components from moisture and shock. |
