Series 290 | CRU

Below is only a summary of product data. Please download the product datasheet for complete details.

Generic Type Aliphatic Polyester Polyurethane
Common Usage Extremely hard, chemical-resistant urethane coating with excellent resistance to abrasion, washdown conditions, corrosive fumes and chemical contact. Gloss retention among the best of air dried finishes.
Colors Available in the 16 standard StrataShield colors. Special colors available, please contact your Tnemec representative. Note: Certain colors may require multiple coats depending on the method of application and finish coat color. When feasible, the preceding coat should be in the same color family (blue, gray, etc.), but noticeably different.
Finish Semi-Gloss
Primers Steel: Series 20, 27, 66, L69, L69F, N69, N69F, 90-97, 90-1K97, 104, L140, L140F, N140, N140F, 161, 205.
Concrete: Series 66, L69, L69F, N69, N69F, 104, 161, 201, 205, 237, 238, 280, 281, 287.
Intermediate Series 20, 27, 66, L69, L69F, N69, N69F, 104, L140, L140F, N140, N140F, 161, 205, 210, 237, 238, 270, 273, 275, 280, 281, 282, 287.
Note: Before topcoating with Series 290, any Tnemec epoxy exterior exposed for more than three weeks must be scarified or reprimed with itself. Mechanically abrading or power-sanding is the preferred method of scarification. The maximum recoat time for Series 210, 237, 238, 280, 281 and 282 is 24 hours. Refer to those product data sheets. Inorganic zinc-rich primers require an epoxy intermediate coat.
Volume Solids 67 ± 2.0% (mixed) †
Recommended DFT 2.0 to 3.0 mils (50 to 75 microns) per coat. Note: Number of coats will vary depending on substrate (surface) and other variables. Contact your Tnemec representative.
Curing Time
Temperature To Recoat To Service Chemical Resistance
75°F (24°C) 12-48 hours 24 hours 7 days

Curing time varies with surface temperature, air movement, humidity and film thickness.
Note: If more than 48 hours have elapsed between coats, the coated surface must be mechanically abraded before topcoating.
