Mixing Ratio Guidance for Epoxy Resin

Why Mixing Ratios Vary

Epoxy resins are typically supplied as two components: resin and hardener. The proportions needed to combine these parts can differ depending on the chemistry of each formulation. Some resins, like One-2-One, are designed for a straightforward 1:1 ratio by volume, making them user-friendly for beginners and crafters. Other specialty resins may need measurement by weight, such as 100 parts resin to 55 parts hardener, particularly for deep pour or high-performance products. Always check the product’s technical datasheet before mixing.

Practical Guidance for Mixing Epoxy Resin

Before starting, have all required tools ready: accurate measuring cups for volume-based ratios, or digital scales for weight-based ratios. Mix slowly and thoroughly, taking care to scrape the sides and bottom of your container. Incomplete mixing or incorrect proportions can lead to soft spots, poor curing, or cloudy finishes. Keep your working environment at a stable temperature for best results. For added convenience and reliability, products such as One-2-One or Trasparente come with clear ratio instructions included in the packaging.

When This Matters Most

• When switching between different epoxy resin brands or types.
• During projects requiring precise appearance and structural integrity, like jewellery, tabletops, and castings.
• If making thick pours or items that will experience regular handling.
