Corrosion Resistant polyurethane primer
PRIMER 302 is a two component, high performance corrosion resistant primer. It combines corrosion inhibiting pigments with a crosslinking polymer resin to form a highly stable polymerpigment matrix. PRIMER 302 creates a physical and chemical bond between the substrate
and polyurethane elastomers. This superior bond strength is achieved by chemically crosslinking the polymer in the primer to the polyurethane elastomer topcoat. PRIMER 302 is manufactured in Light Gray color only.
PRIMER 302 was specifically developed to provide maximum adhesion of United¡¯s Elastuff Polyurethane Coatings to steel, stainless steel and aluminum (mill finish). PRIMER 302 can also be used beneath a United approved topcoat under constant immersion conditions. United requires that test immersion panels be installed in the actual immersion solution for a minimum of 30 days, and then the results be evaluated prior to recommending any specific primer/coating system. For priming of galvanized steel, or substrates which are to be topcoated with United¡¯s Vabar 792, refer to separate literature entitled V.B.A. Primer Technical Data & Application Instructions. Refer to United¡¯s chart entitled Primer Recommendations for ease in making a determination of which primer should be used for a particular coating systems. |
