Common Mixing Ratios for Two Part Systems by Volume

Common Mixing Ratios for Two Part Systems by Volume

One to One (1:1)

Part A= 100%

Part B= 100%

If you were ordering a pint kit, this means you would be receiving one full pint of Part A and one full pint of Part B. After mixing Part A and Part B together, you will have 2 full pints of material.

Sizing options featuring a 1:1 mix ratio:

½ Pint Kit = 1 pint of material

Pint Kit= 2 pints of material

Quart Kit= 2 quarts of material

Gallon Kit= 2 gallons of material

5 Gallon Kit= 10 gallons of material

Two to One (2:1)

Part A= 100%

Part B= 50%

If you were ordering a pint kit, this means you would be receiving one full pint of Part A and half a pint of Part B. After mixing Part A and Part B together, you will have 1.5 pints of material.

Sizing options featuring a 2:1 mix ratio:

½ Pint Kit = 0.75 pint of material

Pint Kit= 1.5 pints of material

Quart Kit= 1.5 quarts of material

Gallon Kit= 1.5 gallons of material

5 Gallon Kit= 7.5 gallons of material

Four to One (4:1)

Part A= 100%

Part B= 25%

If you were ordering a pint kit, this means you would be receiving one full pint of Part A and a quarter pint of Part B. After mixing Part A and Part B together, you will have 1.25 pints of material.

Sizing options featuring a 4:1 mix ratio:

½ Pint Kit = 0.63 pint of material

Pint Kit= 1.25 pints of material

Quart Kit= 1.25 quarts of material

Gallon Kit= 1.25 gallons of material

5 Gallon Kit= 6.25 gallons of material

Ten to One (10:1)

Part A= 100%

Part B= 10%

If you were ordering a pint kit, this means you would be receiving one full pint of Part A and 1/10 of a pint of Part B. After mixing Part A and Part B together, you will have 1.1 full pints of material.

Sizing options featuring a 10:1 mix ratio:

½ Pint Kit= 0.6 pint of material

Pint Kit= 1.1 pints of material

Quart Kit= 1.1 quarts of material

Gallon Kit= 1.1 gallons of material

5 Gallon Kit= 5.5 gallons of material

Less Common Mixing Ratios

One to Four (1:4)

Part A= 25%

Part B= 100%

If you were ordering a pint kit, this means you would be receiving one full pint of Part B and a quarter pint of Part A. After mixing Part A and Part B together, you will have 1.25 pints of material.

Sizing options featuring a 1:4 mix ratio:

½ Pint Kit = 0.63 pint of material

Pint Kit= 1.25 pints of material

Quart Kit= 1.25 quarts of material

Gallon Kit= 1.25 gallons of material

5 Gallon Kit= 6.25 gallons of material

 

Mixing Ratio—Special Notice:

Master Bond recommends all its customers to be accurate and precise in mixing (by weight or volume) the two components of a two part epoxy system. Special precautions must be taken when very small quantities of the epoxy are being mixed (like a few grams), or when mixing a system with a difficult mix ratio (like 10:1). If the two components are not mixed thoroughly, or if there is a significant error in the mix ratio, the epoxy may cure soft and not develop all the required physical properties. Master Bond also recommends its customers to mix the two parts in a contamination free container for best results. It should be noted that for many two component systems involving difficult mix ratios, Master Bond offers applicators (like gun kit), wherein the user does not have to worry about measuring and mixing.
