PA - Polyurethane - These are two-component acrylic aliphatic polyurethane coatings. They are used in heavy-duty applications where extra durability, corrosion, and chemical resistance are needed.  They can be easily applied with brush or by spray and have excellent gloss retention, a characteristic not always found in epoxies.

Mixing Ratios:

PA Series Polyurethanes with PA Catalyst  

Mix 4 parts paint (mix by volume before thinning and using)

1 Part Catalyst    

One Gallon: 

            1 gallon can of paint is 80% full

            1 quart can of catalyst is 80% full

Mixed, they yield one full gallon

Five Gallons:

     1 Five gallon can of paint is 80% full (4 gallons)

     1 One gallon can of catalyst is 100% full (1 gallon)

Mixed, they yield five full gallons

Smaller Quantities:

     1 quart full of paint

     1-½ pint full of catalyst

Or any method of measurement that yields a 4 to 1 mix by volume.

Example:  

4” of paint in a coffee can

1” of catalyst in a coffee can
