Mixing:
Shake both A and B sides vigorously.
Measure out equal parts, by volume, of A and B into clean plastic or metal containers.
Combine both sides into a third clean mixing container and mix vigorously for at least one minute, taking care to scrape the sides and bottom of the mixing container with your mixing utensil, until the product is one uniform color.

 

 

Tips:
Always wear a respirator or self –contained breathing apparatus when working with urethanes.
Use between 65F and 75F in a humidity-controlled environment.
AeroMarine Products Concrete Molding and Stamping Rubber 75A Urethane is moisture sensitive.
Use only clean plastic and/or metal mixing utensils and containers.
Do not use paper or wood.
Re-cap the bottles immediately after use.
Extend-It aerosol nitrogen blanket can be used to protect the product from moisture contamination.
Never mix less than about 3 ounces of product, as this ratio is hard to measure and will take longer to cure as the exothermic reaction does not generate much heat at this volume.
Avoid mixing with drill motors because of the friction they generate, mixing with electric drills can start the exothermic cure process and cause the product to cure in the mixing container.
It is always best to mix the material by hand, with a plastic or metal mixing utensil.
Don’t vary the mix ratio. Unlike some polyester resins, altering the mix ratio to vary the cure cycle will not work with urethanes.
Mix in clean plastic containers. Paper cups and wooden mixing utensils may contain moisture which can adversely affect the urethane rubber. Avoid waxed paper cups because the wax may melt and contaminate the rubber.
Air bubbles in urethanes are almost always caused by moisture. Do everything possible to avoid moisture getting into the mix. Replace the lids onto the containers promptly after use. Do not use the urethane rubber during rainy days or times of high humidity. Avoid pouring against an unsealed water based product such as plaster or hydrocal. Seal plaster or hydrocal with a product like Krylon Clear Acrylic.
Avoid mixing a large batch- The larger the batch, the more exotherm or heat is generated in the cure cycle. If you are making a large mold, mix small batches to make the process more manageable.
Shake or stir well before use- The liquid components may settle in the containers during storage. Shake or stir the components separately and thoroughly before mixing. Let it sit a few minutes to let any bubbles rise to the surface after shaking the container.
