Description
Polymer Nation U-21 is a breakthrough technology combining urethane and polyaspartic polyols to create our state-of-the-art Urespartic™. By combining our Urespartic™ resin with our proprietary Iso blend we are able to create a high-solids, clear finish that will not yellow, maintains its existing sheen and passes 2500 MEK double rubs! It is manufactured in a gloss but the sheen can be reduced using PN C-20 Sheen Reducer.
| Description | Results | Notes |
| Kit Yield in Gallons | 3, 165 | Special packaging is available based on size of order and time constraints |
| Number of Components | 2 | |
| Mix Ratio Liquids by Volume | 2:1 | It is always preferred to mix the entire kit, whenever possible, to avoid off-ratio mixtures |
| Ideal Application Temperatures | 70F-80F 40-60% RH | 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 | 700-800 | Warmer temperatures will reduce viscosity and lower temperatures will increase viscosity |
| Working Time | .75 Hours | |
| Dry to Touch | 3 Hours | Warmer temperatures will reduce time and colder temperatures will increase time. Higher RH will lengthen Dry time data |
| Through Dry | 11 Hours | Warmer temperatures will reduce time and colder temperatures will increase time. Higher RH will lengthen Dry time data |
| Dry to Walk | 12 Hours | Warmer temperatures will reduce time and colder temperatures will increase time. Higher RH will lengthen Dry time data |
| Dry to Lightly Use | 16 Hours | Warmer temperatures will reduce time and colder temperatures will increase time. Higher RH will lengthen Dry time data |
| Full Cure | 7 Days | |
| Pendulum Hardness (König) at 24 hrs. | 12 | Warmer temperatures at RH of 60% or less will increase the hardness number reported |
| Pendulum Hardness (König) at 7 days | 46 | Warmer temperatures at RH of 60% or less will increase the hardness number reported |
| Gloss @ 60 Degree Angle G/LL | 80-88 | |
| VOC’s of Mixed Material | <0 g/L | EPA Method 24 |
| Color Scale per ASTM D1500 | .5-1.0 | Clear to slightly amber |
| Solids by Volume Mixed | >65% | |
| Storage | 60F-90F | Store material between 60-90 degrees F in a protected dry location. |
| Odor | None | |
| Application Thickness in Mils | As a floor topcoat 5-8. As a wall topcoat 4-6. As a primer 4-8. Do not allow to puddle as this will have a negative effect on the finish. | |
| Disposal | Dispose of material, containers, solvents, etc., per Federal, State and local guideline, rules and laws | |
| Available Colors | This material is manufactured in clear. | |
| 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 (material can be thinned up to 10% with clean potable water). Pour material needed from the container onto the floor and spread with a 5-7 mil squeegee. Back roll perpendicular to evenly spread the material. Strike off the material in the same direction as material was squeegeed. Material can also be bucket-rolled using a 3/8″ nap roller cover. For a non-skid finish add 288 grams per 3 gallon kit of PN 1337 S (1-12 oz cup struck off at the top) or 4 lbs. of PN 1335 AO and stir to completely incorporate. Recoat within 24 hours. Clean tools with a hot soapy water or solvent similar to Xylene or Acetone. PN C-55 can be used to accelerate the cure. | |
