Polymer Nation L-21 is a high viscosity, nonylphenol-free, Novolac resin (not a Bis F masquerading as a Novolac). It has been designed as a chemical resistant liner for higher levels of protection than our standard Bisphenol A epoxies.

Description Results Notes
Kit Yield in Gallons 3, 15, 150 Material can be supplied in larger packaging upon request and with minimum quantities
Number of Components 2
Mix Ratio by Volume 2:1 It is always preferred to mix the entire kit, whenever possible, to avoid off-ratio mixtures
Ideal Application Temperatures 60F-90F Verify that substrate temperature is above 5 degrees of dewpoint during application and cure of material to avoid a potential amine blush
Mixed Viscosity in cP@25C/77F 1200 Warmer temperatures will reduce viscosity and lower temperatures will increase viscosity
Gel Time 45 min. Warmer temperatures will decrease gel time and lower temperatures will increase gel time
Dry to Touch 6 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Through Dry 10 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Dry to Walk 12 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Dry to Lightly Use 24 Hours Warmer temperatures will reduce time and colder temperatures will increase time
Full Cure 7 Days Warmer temperatures will reduce time and colder temperatures will increase time
Shore Hardness at 24 hours D65 Warmer temperatures will increase hardness
Shore Hardness at 7 days D85 Warmer temperatures will shorten time to reach full hardness
Gloss @ 60 Degree Angle 80-85 Applying material close to dew point will decrease gloss and may result in an amine blush
VOC’s of Mixed Material <50g/L EPA Method 24
Color Scale per ASTM D1500 N/A Clear to slightly amber before filler is introduced
Solids by Volume Mixed 100%
Storage 60F-90F Store material between 60-90 degrees F in a protected dry location.
Odor Subtle Measuring odor offensiveness is difficult so experience with chemicals has been consulted here
Application Thickness in Mils 10-16mils depending on porosity of substrate and desired purpose
Disposal Dispose of  material, containers, solvents, etc., per Federal, State and local guideline, rules and laws
Available Colors Clear and Color Packs
Mixing & Installation Combine all of part A and B into a single container, large enough to accept the entire kit. Mix at 350 RPM for 2-3 minutes using an appropriate mixing blade and making sure not to introduce excessive air into the solution. Pour the entire content from the container onto the floor and follow normal squeegee and back roll techniques. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
