Clear AquaProof WB10™ formulation which meets meet ASTM D-4666 for exterior wood protection.
20% AquaProof WB31A™
10% AquaProof WB31B™
Ammonia to pH range 9.6 – 9.8
Add the water slowly to the AquaProof WB31A with slow mixing at ambient temperatures.
Add the metallic crosslinking agent (AquaProof WB31B) to the above mixture slowly with slow mixing.
Using ammonia (NH4OH), raise the pH to a range of 9.6 – 9.8.
The crosslinking agent has proven to be stable in the diluted compound. The above user strength formula has survived seven weeks in a 50 °C oven without diminishing its performance properties. The pH adjustment in the formula provides an ammonia blocking mechanism which insures a long shelf life.
