Yes, BlackTop (non-aerosol) is a single-component, moisture-cured urethane, an advanced coatings technology that gives it strong durability, flexibility, and adhesion without a separate hardener.
Aerosol is different chemistry. BlackTop Aerosol uses a professional-grade acrylic lacquer resin, not the moisture-cured urethane in the non-aerosol sizes. See the aerosol comparison page for the full breakdown.
Non-aerosol BlackTop (pint, quart, gallon, and 5-gallon pail) is a single component (1K) moisture-cured urethane. That means it needs no hardener and no mixing ratio: the resin cures by reacting with ambient moisture in the air, which is what gives it its durability, flexibility, and strong adhesion to bare metal, primed surfaces, and previously painted surfaces. This is the same resin family used across KBS's other 1K urethane topcoats.
Frequently Asked Questions: Is BlackTop Urethane Based?
Yes, non-aerosol BlackTop is a moisture-cured 1K urethane, which gives it durability, flexibility, and strong adhesion without a separate hardener.
No. BlackTop is a single component (1K) coating and cures by reacting with moisture in the air, so there is no hardener and no mixing ratio.
No. BlackTop Aerosol uses a professional-grade acrylic lacquer resin system, a different chemistry from the moisture-cured urethane in the non-aerosol sizes.
