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 راتنجات الايبوكسي and hardener correctly is essential for a strong, durable cure.
Depending on the product, the mixing ratio can be based on weight (mass) or حجم, such as 2:1, 3:1, or 1:1. This calculator prevents under-curing or over-curing issues by giving you precise قياسات 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)
مجموع الوزن = Resin Weight + Hardener Weight
2. By Volume (Volume-Based Ratio)
Hardener Volume = Resin Volume × (Hardener Ratio / Resin Ratio)
الحجم الكلي = Resin Volume + Hardener Volume
بيان تفصيلي
- Resin Ratio: This is the part of the resin in the mix (e.g., "2" in a 2:1 mix).
- Hardener Ratio: 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.
ملاحظة هامة: Always follow the manufacturer’s mix type (weight or volume), as epoxy products can have different densities and react differently if mismeasured.

| مزيج نسبة | 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, and you want to use 300 grams of resin.
- Hardener = 300 × (1 / 2) = 150 grams
- Total Mixture = 300 + 150 = 450 غرام
So, you’ll need 300 grams of resin and 150 grams of hardener to create a total mix of 450 grams.

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 سرعة up curing, while lower temperatures slow it down. Always mix in a temperature-controlled environment for best results.
