Epoxy resins are a class of thermosetting polymers known for their exceptional adhesion, chemical resistance, and mechanical strength. They are widely used in coatings, adhesives, composites, and electronics due to their versatility and durability.
| Property | Description |
|---|---|
| Chemical Structure | Contains epoxide groups (cyclic ethers with a 3-membered ring) |
| Common Types | Bisphenol-A (DGEBA), Bisphenol-F (DGEBF), Novolac, Aliphatic, and Glycidylamine |
| Appearance | Clear to amber viscous liquid or solid (depending on molecular weight) |
| Curing Mechanism | Reacts with amines, anhydrides, or phenols to form cross-linked networks |
| Density | 1.1–1.4 g/cm³ |
| Glass Transition (Tg) | 50–250°C (122–482°F) (varies with curing agent and formulation) |
| Tensile Strength | 70–90 MPa (for cured resins) |
| Chemical Resistance | Excellent against acids, alkalis, and solvents |
| Industry | Application |
|---|---|
| Coatings & Paints | Protective coatings for metal, concrete, and marine environments |
| Adhesives | Structural bonding in aerospace, automotive, and construction |
| Composites | Fiber-reinforced plastics (FRP) for wind turbines, aircraft, and sports equipment |
| Electronics | Encapsulation of circuits, PCB laminates, and insulating materials |
| Construction | Flooring, grouts, and repair mortars for high-durability applications |
| 3D Printing | High-performance photopolymer resins for additive manufacturing |
| Advantage | Limitation |
|---|---|
| Strong adhesion to metals, plastics, and ceramics | Brittleness (requires toughening modifiers) |
| Excellent chemical & moisture resistance | Long curing time (can be accelerated with heat) |
| High mechanical & thermal stability | Potential skin irritation (uncured resins) |
| Low shrinkage during curing | Higher cost than polyester/polyurethane resins |
| Parameter | Guideline |
|---|---|
| Storage | Keep in sealed containers, away from moisture and amines |
| Curing Agents | Amines (toxic; require PPE), Anhydrides (less hazardous) |
| VOC Emissions | Low in solid/high-molecular-weight epoxies |
| Biodegradability | Non-biodegradable; incineration recommended |
| Resin Type | Epoxy | Polyester | Polyurethane |
|---|---|---|---|
| Adhesion | ★★★★★ | ★★★☆☆ | ★★★★☆ |
| Chemical Resistance | ★★★★★ | ★★★☆☆ | ★★★☆☆ |
| Curing Speed | ★★☆☆☆ | ★★★★☆ | ★★★★★ |
| Cost | High | Low | Medium |
Epoxy resins are multi-purpose and high performance products developed using our own technologies. We offers broad portfolio of epoxy resins. For Bisphenol-A (BPA)-based epoxy resins (BE-series), we have solid, liquid, and solvent types, all of which are suitable for coating and composite material. We also offer brominated novolac epoxy resins (BNE-series), phenol novlac epoxy resins (PNE-series), UV masking epoxy resins (TNE-series), and other speciality novolac epoxy resins, which are tailored for special needs (i.e. high heat resistance, low absorbent, low Df, NCO modified, etc.) Our cresol novolac epoxy resins (CNE-series) are designed for semiconductors/printing ink applications.
