SP-20 SL Flexible Urethane Membrane Slurry
SP-20 SL
Product Overview
SP-20 SL is a flexible aromatic urethane slurry that has extreme tensile strength with an A shore hardness of 75. It is easy to install, has little odor and has elongation of over 1000%. It creates a soft walking surface as a component in Polymer Nation floor systems.
Uses
SP-20 SL is is primarily used as a basecoat for soft surface applications. It can also be bulked up using fumed silica to make a flexible patching paste.
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.

| Number of Components | 3 | |
| Mix Ratio Liquids by Volume | Not Provided | Do not split kits. |
| 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 | 2000 A & B | Warmer temperatures will reduce viscosity and lower temperatures will increase viscosity |
| Gel Time | 23 min. | Warmer temperatures will decrease gel time and lower temperatures will increase gel time |
| Dry to Touch | 2.5 Hours | Warmer temperatures will reduce time and colder temperatures will increase time |
| Through Dry | 4 Hours | Warmer temperatures will reduce time and colder temperatures will increase time |
| Dry to Walk | 8 Hours | Warmer temperatures will reduce time and colder temperatures will increase time |
| Dry to Lightly Use | 12 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 | A 40 | Warmer temperatures will increase hardness |
| Shore Hardness at 7 days | A 75 | Warmer temperatures will shorten time to reach full hardness |
| Gloss @ 60 Degree Angle | 75-80 | Applying material close to dew point will decrease gloss and may result in an amine blush |

| Color Scale per ASTM D1500 | N/A | |
| Solids by Volume Mixed | 100% | |
| Storage | 60F-90F | Store material between 60-90 degrees F in a protected dry location. |
| Odor | Very Subtle | |
| Application Thickness in Mils | A 1 mix kit consists of 4.30 gal A and .70 gal B and 22 pounds of 1620 SL | |
| Disposal | Dispose of material, containers, solvents, etc.per Federal, State and local guideline, rules and laws | |
| Available Colors | Light Gray | |
| Mixing & Installation | Combine part A and B into a single container, large enough to accept the entire kit (1 mix equals 6 gallons when Part C is added). Premix liquids at 350 RPM for 1 minutes using an appropriate mixing blade or mixing machine. Pour material on to floor and spread to desired thickness using a screed rake and back roll techniques. If a broadcast has been selected, begin broadcasting evenly across the floor, following the same order in which the coating was installed. Whenever possible, work the shorter distance not the longer as this will help keep a fresh edge and make for easier blending. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone. | |
