Additive for Rust Preventive Coating

item(s): 40616

POR-15 Dry Time Accelerator is an additive specially formulated for use with POR-15 Rust Preventive Coating. This paint drying accelerator is designed to accelerate the cure time of POR-15 Rust Preventive Coating by 30-50% without affecting the ultimate physical properties. Developed to allow for a more efficient production environment, POR-15 Dry Time Accelerator reduces recoat and dry time and enables you to move on to the next phase faster, without compromising product performance.

This paint drying accelerator is added to POR-15 Rust Preventive Coating by volume and should be thoroughly mixed. Once this quick dry additive for paint is mixed in typically the cure time of the POR-15 Rust Preventive Coating is reduced by 30-50%.

Important: Adding this paint drying additive drastically reduces the cure time (time you have to apply to your substrate) and under humid and warmer conditions the dry time is significantly quicker.

We recommend testing this dry system accelerator to ensure your specific needs are met. One 8 oz. bottle of POR-15 Dry Time Accelerator is enough for 32 quarts or 8 gallons of POR-15 Rust Preventive Coating. Check out thisquick dry paint additivetoday!

Used this in our catch pen at the dairy. The area gets manure and urinated on about 18 hours a day. Also the cow slobber is very acidic from their rumination process. Tough environment to say the least. I hit the rust off, cleaned with a wire brush, and then used the rust preventative kit (degreaser/metal prep/coating). Also added the dry accelerator due to the time sensitive nature of the milking rotation. Product worked great! Dried in time, and is holding up perfectly so far. Personally I would use this product over a rubber coating 9 out of 10 times.

gotta have it

If you are doing POR15 more than... once or twice you have to have this. Normally POR takes 2-4 hours before you can apply a second coat... how about cutting that time nearly in half? I am not sure if this next comment was coincidence or not but... I got less mini bubbles during the curing process with a drop or two of this in the mix. I did NOT have that result when reducing POR.

Saved a ton of time

This cut my wait time by more than half compared to the last time I used the POR-15 system. Definitely makes painting much faster. FYI you don't need a lot for it to work. Read the instructions before you add too much!


Directions: Add 1 ounce of POR-15 Dry Time Accelerator to 1 gallon of POR-15 Rust Preventive Coating and stir to mix thoroughly (do not shake). The dry time of POR-15 Rust Preventive Coating is dependent on temperature and humidity even with the addition of this accelerator. Spot testing is recommended.

Important: POR-15 Dry Time Accelerator is designed for use with POR-15 Rust Preventive Coating only and its use with other products is not recommended.
