7001 Polyurethane Primer Steel & Concrete | 1 Hr Recoat | Exceptional Adhesion
7001 Polyurethane Primer is a high performance, versatile, single component, moisture cured, non-toxic primer for superior protection of concrete and steel. 7001 is designed for deep penetration, increased bond strength, wetting and sealing of substrates and exceptional corrosive resistance. It provides superior adhesion, toughness, abrasion resistance and flexibility in a wide range of applications.
7001 Polyurethane Primer “cross-links” with polyurea, EPDM and other materials difficult to bond to when properly applied. For applications where set times need to be shortened such as in cold weather conditions or time sensitive applications, an accelerator may be used to reduce set time. Great companion primer with the 5500 Polyaspartic Coating
The 7001 Polyurethane Primer works great as a structural steel primer when used with epoxy, polyurea or polyaspartic topcoats. When used as primer on concrete surfaces can help prevent or reduce problems associated from concrete outgassing.
Comes in 1 gallon and 5 gallon containers.
Moisture resistance underwater One coat 7001 with two coats of epoxy top coat, per SSPC SP – 10 method for prepared steel. No delamination, blistering, cracking or softening. Expected Life minimum under water – 5 years
Salt Water Exposure Less than 1/32 inch rust creepage at scribed line after 1000 hours of exposure
Available as optional concentrate for non-hazardous international shipping with solvent added at destination. Comes as a clear, honey colored product.
Where is the 7001 used?
- Great companion primer with the 5500 Polyaspartic Coating
