Epoxite - Crystal Clear Cast

Epoxite – Crystal Clear Cast
Mix Ratio (w/w):  3:1
System Type: High-clarity epoxy system for table tops, artistic casting & decorative applications

Product Overview

Epoxite® Crystal Clear Cast is a two-component, ambient-cure epoxy system designed for transparent casting, tabletop coatings, and artistic applications. Derived from a low-viscosity, modified epoxy formulation, it offers glass-like clarity, long pot life, and minimal shrinkage, making it ideal for thick-section casting and high-gloss finishes.

Key Features

• Crystal-clear transparency with high hardness

• Excellent air release and wetting properties

• High gloss finish without "fish-eye" effect

• Long working time – perfect for deep pours

• Good chemical and water resistance

• Minimal shrinkage during cure

Typical Applications

• Clear castings and decorative resin art

• River tables and resin wood projects

• Tabletops and bar top coatings

• Jewelry and handicraft moulds

• Encapsulation and potting of decorative items

Mixing Ratio (by weight)

• 3:1 (Resin : Hardener)

Processing & Application Guidelines

• Mixing Instructions:
  1 .Measure components accurately by weight
  2. Mix manually or mechanically at slow speed to avoid air entrapment
  3. Scrape the sides and base of the container during mixing
  4. Continue mixing until the blend is fully clear and streak-free
  5. Degas under vacuum (optional) before pouring for crystal-clear results

• Application:
  1. Pour the mixture into silicone or plastic molds, or directly onto wood or flat surfaces
  2. Ideal mold materials: silicone rubber, acrylic, HDPE
  3. Use under controlled environment:

  • Temperature: 20–35°C

  • Humidity: Below 65%

  • Avoid curing below 15°C or in high humidity (>80%)

  • Recommended casting depth: Up to 30 mm per pour (deeper sections require staged pouring)

• Curing Schedule:
  1. Touch dry: ~18–24 hours at 25°C
  2. Full cure: ~48 hours at ambient temperature
  3. Post-cure (optional for high heat resistance): 50°C for 18 hours or 80°C for 3 hours

Storage & Shelf Life

• Store in tightly sealed containers away from moisture and sunlight

• Recommended storage temperature: 18°C – 30°C

• Shelf life:

  • Resin: 12 months

  • Hardener: 12 months

Safety & Handling

• Use gloves, goggles, and appropriate PPE

• Work in a well-ventilated area

• In case of skin contact, wash with soap and warm water

• Do not inhale vapors or allow prolonged skin exposure

• Hardener tends to fume – always keep sealed tightly

🌊 Using Epoxite – Crystal Clear Cast for River Tables

Why it's a good fit:

• Long pot life (300–370 minutes) — gives you enough working time for large, deep pours

• Low exotherm (max ~55°C) — minimizes risk of cracking, yellowing, or warping

• Excellent clarity and gloss — perfect for showcasing wood grains and decorative items

• Good hardness (Shore D 75–80) — durable enough for furniture surfaces

• Thick-section pouring capability — up to ~30 mm per pour

Important Notes for River Table Applications

• Maximum single-pour depth
  - Up to 30 mm per pour layer
  - For deeper sections (e.g., 50–70 mm), pour in multiple layers with 4–6 hours gap between layers (or wait for gel stage)

• Ambient temperature
  - Maintain 20–28°C throughout curing
  - Avoid high humidity (>65%) to prevent blush or cloudy finish

• Post-cure (optional)
  To boost heat resistance (for hot mugs, sun exposure, etc.), post-cure the surface at 50–60°C for 4–6 hours

• Coloring
  Compatible with epoxy pigments and transparent dyes — just make sure to mix thoroughly

• Sanding & polishing
  After full cure (48–72 hrs), surface can be sanded and polished for a glass-like finish

Final Tip
For best results, always seal the wood with a thin coat of epoxy first to prevent bubbles from escaping during deep pours.
