A lot of artists, craftsmen, and hobbyists struggle to make the difference between the epoxy resin and acrylic resin. Even though both are used extensively in fine arts and industry, both different in their properties, behavior, and use.
Epoxy resin is a thermosetting polymer that made a solid and hard form when cured. Resin is a plant-based chemical that is present in tree sap. It includes solid and thick substances. The term resin usually refers to liquids that harden with heat, light, or other agents.
Resin is typically Available into two categories: synthetic and natural. The mostly resin use in our daily life or fine Art is synthetic. Besides synthetic and natural, synthetic resin comes in two forms: thermosetting plastics and thermoplastics. Thermosetting plastics include polyester and epoxy resin. Thermoplastics include acrylic. They are made on a similar principle i.e. Hordern from a fluid.
Acrylic epoxy resin is a thermoplastic polymer with flexibility, UV stability, and easy moldability for Art Molds. Choosing an incorrect resin has unanticipated results from poor adhesion to discoloration. This guide will analyze their scientific properties and practical uses so you can make an informed decision.
Understanding the Chemical Composition
In order to comprehend their differences fully, let’s consider their molecular structures and what occurs when they react when curing.
Acrylic Resin Formula: The Science
Acrylic resin
Chemical Structure: (C5O2H8)n (Polymethyl Methacrylate – PMMA)
- Thermoplastic: May be softened and re-molded by applying heat
- Used in: Paints, adhesives, transparent sheets, and coatings.
- Provides: Better UV stability and is consequently well suited for outdoor use.
Formula of Epoxy Resin: The Strength Backbone
Chemical Structure: (C21H25ClO5)n (Bisphenol A and Epichlorohydrin reaction)
- Thermosetting: Once cured, it cannot be remolded
- Requires: A hardener (curing agent) in order to form a rigid crosslinked structure.
- Generally employed in: Adhesives, coatings, epoxy resin art that is deep-pour, and Best for Waterproofing Surface.
Example in real life: Acrylic epoxy resin is more suitable if you are creating a flexible plastic display. If you are looking for a hard finish that is both glossy and long-lasting for a table, epoxy resin is what you need.
Comparison of Physical & Chemical Properties
Physical Properties
| Property | Acrylic Resin | Epoxy Resin |
|---|---|---|
| Color | Transparent by design, can be colored | Clear, available in tinted variants |
| Density | Lower density, lightweight | Increased density, heavier |
| Hardness | Softer, more impact-resistant | Hard and very resilient and stiff |
| Melting & Boiling Points | Lower melting point and remoldable | Heat resistant, will not melt when cured |
| Appearance | Glossy or matte finish based on additives. | Naturally glassy and glossy. |
| Texture | Smooth, flexible | Hard; glassy; and sometimes brittle |
| Shape | Can be remolded and reshaped multiple times | Remains in permanent form after curing |
| Solubility | Can be dissolved in certain solvents. | Insolubility after curing |
| Viscosity | Less viscosity; flows well. | Thickening varies depending on formulation |
| Malleability | Can be reshaped with heat. | Turns hard on curing |
| Ductility | Versatile yet susceptible to cracking under pressure | Hard and unyielding at very high pressure |
Chemical Properties
| Property | Acrylic Resin | Epoxy Resin |
| Flammability | Burning at very high temperatures. | Less combustible; some fireproof types |
| Reactivity | Less reactive and hardens through evaporation or thermal curing. | Highly reactive with hardeners and undergoes chemical crosslinking. |
| Heat Resistance | Firm can be softened by heat. | High, withstanding extreme temperatures |
| Chemical Resistance | Resistant to certain chemicals but vulnerable to strong acids and bases | High chemical and solvent resistance |
| UV Resistance | Very good and doesn’t yellow easily. | Yellow over a period without UV stabilizers |
Practical Tip: Acrylic epoxy resin is a better choice for making outdoor signs because it resists UV damage. Best Epoxy resin is superior when you are creating a river table in terms of durability and self-leveling.
Applications: Where Are They Used?
Applications of Acrylic Resin in Fine Arts and Crafts
- Used in paints and varnishes and transparent coatings.
- Used in 3D printing materials, adhesives, and decorative displays.
Uses of Epoxy Resin in Fine Arts and DIY Projects
Epoxy resin
- Ideal for thick pours, epoxy resin art, jewelry making, tabletops, and coatings.
- Used in high-strength adhesives, floorings, and in boat applications.
A jewelry maker can use epoxy resin to create a crystal-clear pendant, while a painter who is painting large works can use acrylic epoxy resin because it dry very quickly.
