Epoxy Resin & Hardener 2:1 300g - Ultra Clear Bubble Free Art Kit

Ultra Clear Epoxy Resin and Hardener 2:1 Ratio 300g Kit for Resin Art, Casting, and Coating

This JustKraft ultra clear epoxy resin kit gives you everything to start pouring: 200g of resin and 100g of hardener in a precise 2:1 ratio, measured by weight. It cures crystal clear with a high-gloss, glass-like finish, self-levels for a smooth even surface, and resists yellowing so your work stays clear over time. The 2:1 mix cures to a durable yet slightly flexible finish (60-70 Shore A), which suits resin art, coasters, tabletops, river tables, and coating work.

Key Features

• Precise 2:1 ratio by weight: 200g resin plus 100g hardener, so mixing is simple and consistent
• Crystal clear, high-gloss finish that cures to a glass-like shine and resists yellowing over time
• Self-leveling and bubble-free formula that flows flat for a smooth, even surface with minimal effort
• About 45 minutes of working time and a full cure in 8 to 12 hours, so projects move along quickly
• Cured hardness 60-70 Shore A, giving a soft, flexible finish suited to its ratio

Where You Can Use This

• Resin art, abstract pours, geode art, and ocean-themed pieces
• Coasters, trays, bowls, and decorative castings
• Tabletops, river tables, and wood coating
• Jewellery, pendants, keychains, and small cast pieces

How to Use

• Measure by weight in a 2:1 ratio: 200g resin to 100g hardener for this pack
• Work between 25 and 45 degrees Celsius for the best flow and cure
• Stir slowly for three to five minutes, scraping the sides, to avoid whipping in air
• Let the mix rest a few minutes so bubbles rise, then pour
• Pass a heat gun or torch lightly over the surface to pop any surface bubbles
• Leave to cure undisturbed; touch-dry in a few hours, full cure in 8 to 12 hours

Frequently Asked Questions

Q: What is the mixing ratio and how do I measure it?
A: This is a 2:1 ratio kit measured by weight, 200g resin to 100g hardener for this pack. Always weigh on a scale rather than measuring by volume for an accurate cure.

Q: How long does it take to cure?
A: You get around 45 minutes of working time, and the resin reaches a full cure in 8 to 12 hours at a working temperature of 25 to 45 degrees Celsius.

Q: Will it turn yellow over time?
A: No. The formula is made to resist yellowing, so cured pieces stay clear and glossy. Keeping work out of constant direct sunlight helps preserve clarity further.

Q: What is the difference between the 2:1 and 3:1 versions?
A: The 2:1 cures slightly flexible (60-70 Shore A) and suits art, coasters, and coating. The 3:1 cures harder (80-90 Shore) and suits jewellery, keychains, and pieces needing a rigid, sharp-edged finish.

Q: Is one pack enough for my project?
A: This 300g pack covers small to medium work. For large river tables or deep pours, choose a bigger pack or pour in layers to manage heat build-up.
