Seal 'n Lock Bio-Strip®

Seal’n Lock’s Bio-Strip® stripper is a novel blend of environmentally friendly compounds formulated into a non-toxic, highly effective paint stripping system. This unique product contains 15% bio-renewable carbon and its high loading capacity gives it the ability to strip surfaces in one application. It is an excellent alternative to hazardous low flash point materials such as methylene chloride, NMP, and acetone; which are commonly used for stripping applications.

Seal n Lock Bio Strip Paver Stripper

Performance Characteristics

  • Ideal for removing acrylics, enamels, epoxies, lacquers, latex's, moisture-cured coatings and urethane's from most substrates.
  • High flash point
  • High loading capacity makes stripper last longer.
  • Low evaporation rate allows for long stripper on substrate dwell times and lower volume use due to fewer reapplications resulting from solvent evaporation before the coating is removed.
  • Will not harm aluminum, composites, concrete, metal, steel or wood

Toxicological & Environmental Profile

  • Contains no carcinogenic or toxic compounds
  • Contains no peroxides, methylene chloride, NMP or other dangerous chemicals
  • Contains no ozone depleting chemicals, no hazardous air pollutants (HAPs) and no global warming compounds
  • No SARA reportable components
  • Readily bio-degradable
  • VOC compliant per EPA, AQMD, and CARB regulations

Bio-Strip® Safety Data Sheet

Application and use

Because these products are bio-solvent blends they strip differently from industry standard strippers like methylene chloride or NMP. Bio-strippers need time to work as the stripping mechanism is different from petroleum-based solvents. Bio-solvents penetrate paints and coatings and work by breaking the bond between the coating and the substrate, whereas petroleum-based solvents work by dissolving coatings. As a result, it is important to give the bio-stripper time to work. For 2 part urethane/epoxies and/or thicker coatings, we recommend 2 Mils stripping to substrate followed by covering the area with plastic cover for 12 hours and then pressure washing the stripper from the surface. We believe in letting the chemicals do the work.

Flat or vertical surfaces

Apply 1 - 2 mils of stripper to substrate. Allow sufficient time to lift paint. Remove with a plastic paint scraper. Typically a dwell time of 45 to 60 minutes is sufficient for a waterborne 2 part urethane's and other coatings. Dwell times needed to remove coatings are dependent on the coating thickness, type, and age as well as the porosity of the surface. A second stripper application may be necessary.

Performance Data

The data below outlines typical performance for removing various types of coatings. Coating time will vary depending on coating thickness and surface temperature.

Acrylic coating (12mils) Strip time = 20 to 30 minutes
Acrylic (12 mils) over elastomeric (8 mils) Strip time = 3 hours
Moisture-cured epox Strip time = 10 to 20 minutes
2 Part waterborne epoxy Strip time = 45 to 60 minutes
Oil & water stains, transparent or pigmented Strip time = 20 to 30 minutes
Oil Based Enamel Strip time = 20 to 30 minutes
Polyurethane Strip time = 45 to 60 minutes
