The Epoxy Mix Ratio Calculator helps you accurately determine the right proportions of resin and hardener when preparing epoxy mixtures. Whether you're working on woodworking, marine repairs, resin art, or construction projects, mixing 环氧树脂 and hardener correctly is essential for a strong, durable cure.
Depending on the product, the mixing ratio can be based on weight (mass) or 体积, such as 2:1, 3:1, or 1:1. This calculator prevents under-curing or over-curing issues by giving you precise 测量 based on the manufacturer’s specified ratio.
Formula of Epoxy Mix Ratio Calculator
1. By Weight (Mass-Based Ratio)
Hardener Weight = Resin Weight × (Hardener Ratio / Resin Ratio)
总重量 = Resin Weight + Hardener Weight
2. By Volume (Volume-Based Ratio)
Hardener Volume = Resin Volume × (Hardener Ratio / Resin Ratio)
总容积 = Resin Volume + Hardener Volume
详细分类
- Resin Ratio: This is the part of the resin in the mix (e.g., "2" in a 2:1 mix).
- 硬化剂比例: This is the part of the hardener (e.g., "1" in a 2:1 mix).
- Resin Weight or Volume: The initial amount of resin you plan to use (in grams or mL).
- Hardener Weight or Volume: The correct amount of hardener to add.
重要注意事项: Always follow the manufacturer’s mix type (weight or volume), as epoxy products can have different densities and react differently if mismeasured.
快速参考表
| 混合比例 | Resin (g/mL) | Hardener (g/mL) | Total (g/mL) |
|---|---|---|---|
| 1:1 | 100 | 100 | 200 |
| 2:1 | 100 | 50 | 150 |
| 3:1 | 150 | 50 | 200 |
| 4:1 | 200 | 50 | 250 |
This table provides fast estimates based on commonly used ratios for quick project planning.
Example of Epoxy Mix Ratio Calculator
Let’s say you’re using a 2:1 mix by weight，并且您想使用 300 grams of resin.
- Hardener = 300 × (1 / 2) = 150 grams
- Total Mixture = 300 + 150 = 450克
So, you’ll need 300 grams of resin and 150 grams of hardener to create a total mix of 450 grams.
最常见的常见问题解答
Incorrect ratios can cause the epoxy to stay sticky, cure too slowly, or become brittle. Always follow the correct ratio (weight or volume).
Yes, for weight-based epoxy ratios, a digital scale is more accurate than volume measuring. For volume-based mixes, use clearly marked measuring containers.
Yes. Higher temperatures 速度 up curing, while lower temperatures slow it down. Always mix in a temperature-controlled environment for best results.
