Using AB Resin (Epoxy) for Craft Making

AB resin (epoxy) is a popular and highly effective material for creating transparent, glossy, and durable crafts, such as decorative items, jewelry, resin art, and models. Below is a detailed guide covering material selection, step-by-step instructions, techniques, and precautions to help you craft high-quality resin artworks.

1. Basic Properties of AB Resin

  • Composition:

    • Part A (Resin): Base component, usually a clear liquid.

    • Part B (Hardener): Curing agent that chemically reacts with Part A to solidify.

  • Features:

    • High Clarity: Ideal for crystal-clear finishes.

    • Durability: Hardens into a tough, scratch-resistant surface.

    • Customizable: Can be tinted with dyes or filled with glitter, dried flowers, etc.

    • Curing Time: Typically 24–48 hours (varies by brand).

2. Materials & Tools Required

CategoryRecommended Tools/Materials
ResinHigh-clarity AB epoxy (e.g., “Crystal Resin” or ArtResin)
MoldsSilicone molds (easy release, reusable)
Coloring AgentsResin dyes, mica powder, glow pigments
EmbellishmentsDried flowers, seashells, gold leaf, glitter
ToolsDigital scale (for precise mixing), mixing cups, stir sticks, toothpicks (for bubbles), heat gun/lighter (for bubble removal)
Safety GearGloves, mask, well-ventilated workspace

3. Step-by-Step Guide (Example: Resin Coaster/Keychain)

Step 1: Mixing the Resin (Critical!)

  • Ratio: Usually 2:1 or 3:1 (A:B) – follow manufacturer instructions strictly.

  • Method:

    1. Weigh Parts A and B separately using a digital scale.

    2. Mix slowly (3–5 minutes) to avoid air bubbles until fully blended.

Step 2: Adding Color & Decorations

  • Dyes/Pigments: Add sparingly to maintain transparency.

  • Layering: Pour a thin layer, let it partially cure, then add embeds (e.g., flowers, photos).

Step 3: Pouring into Molds

  • Slow Pour: Minimize bubbles.

  • Bubble Removal:

    • Resting: Let bubbles rise naturally.

    • Heat Gun/Lighter: Pass briefly over the surface (keep a safe distance).

Step 4: Curing

  • Environment: Keep dust-free at 20–25°C (low temperatures delay curing).

  • Demolding:

    • Soft Cure (6–12 hrs): Trim edges if needed.

    • Full Cure (24–48 hrs): Remove from mold and polish.

4. Advanced Techniques

  1. UV + AB Resin Combo:

    • Use UV resin (light-cured) for detailed layers, then seal with AB resin for strength.

  2. Faux Amber Effect:

    • Embed insects/leaves in resin for a natural amber look.

  3. Polishing:

    • Sand with progressively finer grits (800→3000), then polish with resin polish.
