UV Resin Tutorial for Beginners
UV resin is a type of resin that cures only under ultraviolet light. Its big advantages are fast curing, easy handling, and versatility,making it perfect for small accessories, jewelry pieces, and even as a strong adhesive.
To use it, simply pour UV resin into a mold, cure it under a UV lamp, and within minutes you’ll have a hardened, glossy piece in the shape you want. That said, creating flawless resin pieces takes a little practice and attention to detail. This beginner-friendly guide will walk you through the process step by step. For best results, we recommend watching the video tutorial first, it’s more intuitive and easy to follow visually.
1.Tools and Materials Preparation
- Materials: Regular UV resin
- Tools: Measuring Cup, Mixing stick, UV Lamp, 75% Alcohol (for Cleaning), Transparent Mold
- Protective Equipment: Always wear respirator, nitrile waterproof gloves, a waterproof apron for safe handling.
2.Environment Setup
- Ideal Conditions: Maintain a temperature between 73–78°F with humidity no higher than 50–60% RH.
- Ventilation: Work in a well-ventilated area, ideally near a window or use an air purifier for better airflow.
3.Step-by-step Instructions
Step 1: Choosing the Right Mold
Correct choice: Use a transparent mold. This allows light to penetrate from both sides so the resin cures evenly.
Wrong choice: Opaque molds block the UV light, leaving the bottom sticky and uncured.
Correct choice: Small molds or metal frame molds are ideal. They cure quickly, hold their shape well, and are perfect for beginners.
Wrong choice: Oversized molds (larger than 2in × 2in) or very thin, long shapes (like bookmarks). These can cure unevenly or warp at the edges after curing.
Step 2: Defoaming the Resin
Before using, turn the UV resin bottle upside down for a few minutes to help release air bubbles. You can also gently warm the bottle to reduce viscosity and speed up defoaming.
Step 3: Coloring & Mixing
Stirring Method
- How to stir: Mix the resin in one direction at a steady pace. Scrape along the cup’s walls and bottom to avoid unmixed spots.
- When to stop: At first, you’ll see stringy lines in the resin. Stir for 1–2 minutes until the texture becomes smooth and uniform.
- Tool tip: Wipe resin off mixing sticks with a tissue and reuse them.
Tips:
① Never stir under a UV lamp or direct sunlight, this can cause unexpected curing.
② Stirring too fast or in random directions creates excess bubbles.
Step 4: Removing Bubbles in the Mold
- Use dental floss to pick bubbles trapped at the bottom.
- Use a heat gun to pop bubbles floating on the surface.
Tip: Avoid using a lighter or torch - it can easily burn or damage the mold.
Step 5: Curing the Resin
- Use a UV lamp with a wavelength of 365–405nm.
- Cure both sides for 3–5 minutes each to ensure full curing.
- If the surface still feels tacky, extend the curing time.
Tip: After curing, let the piece cool for 1–2 minutes before touching. This prevents burns and fingerprints.
Handling Resin in Winter
When temperatures drop, resin thickens and becomes harder to work with. Here’s how to restore fluidity:
- Warm water bath: Soak the resin bottle in 122°F (50°C) water for 5–10 minutes.
- Preheater: Use a resin preheater until the resin flows smoothly again.
4. Coloring Your Resin
Tip: Keep additives under 5% of the resin volume. Too much can prevent proper curing. Let the mixture sit for 2 minutes before curing to release bubbles.
5. Quick Cleaning Tips
After finishing your project, cleaning up your workspace is essential. These simple tips will take care of 99% of cleanup tasks.
Hands
Wipe resin with alcohol or nail polish remover, then wash with soap and water. Orange hand soaps (like Fast Orange or Gojo Natural Orange) are great for resin residue.
Desktop Spray alcohol directly on resin spills and wipe clean.
Mold Remove dried resin particles with a piece of tape.
6. Caring for Your Finished Pieces
With the right care, resin pieces can stay beautiful for years.
Storage
Best Practices：Keep in a cool, dry, ventilated place. Protect from light to prevent UV aging.
Avoid：Don’t expose to sunlight or high heat (heaters, stoves, etc).
Cleaning
Best Practices：Wipe dust with a soft cloth or brush. Avoid：Avoid rough scrubbing, high-strength alcohol, or acetone (can cloud the resin).
Repair
Best Practices：Small scratches: coat with a thin UV resin layer.
Deep scratches: sand from 320–5000 grit, then coat with resin.
Avoid：Don’t use corrosive glues like super glue.
