1. What is Epoxy Mixing?

Epoxy resins typically consist of two parts - Part A (resin) and Part B (hardener) that must be mixed in specific ratios for proper curing. The ratio varies by product formulation.

2. How Does the Calculator Work?

The calculator uses the epoxy mixing formula:

Where:

• \( \text{Part A} \) — Weight of resin component in grams
• \( \text{Part A Ratio} \) — First number in mixing ratio (e.g., 2 in 2:1 ratio)
• \( \text{Part B Ratio} \) — Second number in mixing ratio (e.g., 1 in 2:1 ratio)

Explanation: The calculator maintains the specified ratio between components to ensure proper chemical reaction and curing.

3. Importance of Proper Mixing

Details: Accurate ratio mixing is crucial for epoxy to cure properly. Incorrect ratios can lead to sticky surfaces, weak bonds, or incomplete curing.

4. Using the Calculator

Tips: Enter the weight of Part A you plan to use, then specify the mixing ratio (e.g., for 2:1 ratio, enter 2 and 1). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my epoxy has a different ratio?
A: Simply adjust the ratio values to match your product's specifications (e.g., 3:1, 4:1, etc.).

Q2: How precise do I need to be?
A: Very precise - small ratio deviations can significantly affect curing. Use digital scales for accuracy.

Q3: Can I mix by volume instead of weight?
A: Only if the manufacturer specifies volume ratios. Weight ratios are more accurate as densities differ.

Q4: What temperature is best for mixing?
A: Follow manufacturer guidelines, typically room temperature (20-25°C) is ideal.

Q5: How long should I mix the components?
A: Typically 2-3 minutes until completely homogeneous, scraping sides/bottom periodically.
