U-20 Urespartic™ Pigmented Hybrid WB
U-20
Product Overview
U-20 is a breakthrough technology combining urethane and polyaspartic polyols to create our state-of-the-art Urespartic™. By combining our Urespartic™ polyol with our proprietary Iso blend we are able to create a high-solids, pigmented finish that will not yellow, maintains its established 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.
Uses
U-20 Urespartic™ is primarily used as a pigmented topcoat due to its unsurpassed UV, mar and abrasion resistance. It can be applied to floors and walls and adheres well to many substrates including concrete, gypsum, cement board, metals, vinyl, PVC and fiberglass. It can also be applied direct to concrete as a primer and topcoat.
Preparation
The preparation method for each project is determined by a full understanding of the substrate to be coated, the chemistry of the coating system being used, the coating system thickness, and numerous other factors. The coating installer should fully read and understand ICRI Guideline NO.03732 and OSHA 29 CFR 1926.1153 before starting preparatory work. The aim, of preparing a substrate for coating applications, is to roughen the surface, remove weak layers, contaminants, dirt, debris and present a solid, clean, dry substrate for the primer. If unsure as to the level of preparation needed contact Polymer Nation at Lab@polymerNation.com.
The data below represents the most pertinent information needed by a professional installer to understand and efficiently install this material. The data was gathered at temperatures of 72-75 F and 30-50% RH. A wide array of independent and company test data has been compiled on this product but is too large to place on this Technical Data Sheet.

| 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 | 950-1200 | 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 | 75-80 | |
| VOC’s of Mixed Material | 0 g/L | EPA Method 24 |
| Color Scale per ASTM D1500 | N/A | |
| Solids by Volume Mixed | >70% | |
| 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 4-6. 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 | White, Light Gray, Warm Sun | |
| 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. | |
