Aliphatic Pure Polyurea is 100% solids, state of the art, spray applied pure polyurea elastomeric surfacing membrane. This seamless system is an aliphatic polyurea which is color fast and resists yellowing. Aliphatic Polyurea is tack free in 3 minutes which facilitates short down times. This membrane achieves an extremely tough, flexible, chemical and abuse resistant finish for a wide range of applications. Aliphatic Polyurea has no VOC's.

Application
Correct equipment is critical to the installation. Use only 1:1 ratio, heated plural component equipment, similar to the H-2000, H-3500, and the new H-20/35 series with a GX7, GX7-400, consult a EPC representative for more information. Polyurea must be sprayed at a minimum of 2000 psi and 160 F at the gun.
Installation
Consult EPC, for an approved applicator and for job specific Specifications.. Apply to clean dry sound surfaces free of loose particles or other foreign matter. Consult EPC for surface preparation and repair procedures.
Limitations
- Intended for industrial use
- Mix B component THOROUGHLY with a collapsible drum mixer before use.
- Bond to weak substrates is limited to the strength of the substrate.
- EPC for Chemical Resistance
- Do not install in moisture/vapor conditions>3 Lbs. MVT>5%. Moisture content.
- Primer may be required.
- Refer to MSDS, Instruction Sheet and Product Labels.
- Avoid moisture contamination in containers.
