Monobasic potassium phosphate → Magnesium Phosphate

Participants

Reaction Steps

This example illustrates that the coating can be applied to organic substrates. A magnesium phosphate coating composition was prepared by combining 60 grams of mono-potassium phosphate crystals (maximum size 300 microns), 20 grams of magnesium oxide powder (maximum size 100 microns), and 50 grams fine sand (maximum size 500 microns). The components were blended in high shear mixer for 1 minute and allowed to cool for 10 minutes. Water in the amount of 35 grams was added to this mixture. The components were then mixed by hand in a container to obtain a slurry. This slurry was applied to an asphalt surface using a brush and allowed to cure for about an hour. Once the slurry coating dried, the coating of Example 3 was applied.
