Epoxy Calculator for Polymer Clay
Here's a comprehensive table comparing epoxy resin and UV resin for use with polymer clay:
| Aspect | Epoxy Resin | UV Resin |
|---|---|---|
| Types of Resin | 2-part, needs mixing | Single component, no mixing |
| Application Process | Mix parts A and B, pour over clay | Pour and apply under UV light |
| Curing Time | 12-36 hours | 8-10 minutes |
| Strength & Durability | Creates a strong bond, resistant to impact | Less durable than epoxy, but quicker |
| Finish Appearance | Hard, clear, glass-like finish | Glossy, shiny finish |
| Tips | Ensure proper mixing ratios | Use under UV light for curing |
Key Points to Remember
Compatibility and Preparation
Epoxy resin and UV resin are both compatible with polymer clay, but proper preparation is crucial1:
- Ensure the clay is fully cured before applying resin
- Rough up the clay surface for better adhesion
- Use a release agent when casting resin into molds with polymer clay
- Work in a clean, dust-free environment to avoid imperfections
Application Process
- For epoxy resin:
- Mix parts A and B according to manufacturer instructions
- Apply in thin layers to prevent cracking or cloudiness
- Allow 12-36 hours for curing3
- For UV resin:
- Pour directly onto the clay surface
- Spread evenly with a silicone brush
- Cure under UV light for 8-10 minutes3
Advantages and Disadvantages
Epoxy Resin:
- Pros: Strong bond, impact-resistant, glass-like finish
- Cons: Longer curing time, requires mixing, may yellow over time3
UV Resin:
- Pros: Quick curing, easy application, glossy finish
- Cons: Less durable, may leave a tacky feel, tends to yellow over time3
Safety Precautions
- Wear proper personal protective equipment when working with resins
- Work in a well-ventilated area
- Be aware of potential allergic reactions to resin3
Finishing Touches
- Use a heat gun or lighter to remove bubbles from the resin surface
- Sand and polish the cured resin for a smooth, professional finish1
By considering these factors, you can choose the most suitable resin for your polymer clay projects and achieve excellent results
