Product Identity

The 3M 983-21 ES Conspicuity Tape is a premium-grade reflective marking tape supplied in a fluorescent yellow colour. It comes in a 1 in width by 50 yd roll with an 18 mil thickness and uses an acrylic adhesive on a retroreflective microprismatic backing. This product is intended for safety marking and visibility enhancement on vehicles, equipment or structures.

Suitability

The tape suits operators who need durable, high-visibility markings that adhere to a range of substrates including fibreglass, painted panels, aluminium rail, stainless steel and degreased aluminium. Adhesion strength varies from 2.5 lb/in on FRP up to 6.0 lb/in on stainless steel, so installers should verify the target surface before committing. Buyers who require a different colour, width or a non-reflective tape should look at alternative products.

Sustained Performance

The acrylic adhesive and microprismatic construction are designed for outdoor exposure and maintain retroreflectivity over extended periods. Because adhesion values are quoted for specific substrates, long-term bond integrity depends on proper surface preparation and matching the tape to the intended material. The 50 yd roll length supports large-area or repeat applications without frequent roll changes.

Questions about this item

What surface must I already have clean and ready for the 1 in wide 983-21 ES tape to adhere properly?

The acrylic adhesive bonds to FRP, Tedlar, prepainted panels, aluminum rail, degreased aluminum and stainless steel; clean the chosen surface before applying.

Will the 18 mil thick retroreflective microprismatic material still reflect if I layer it over older non-reflective tape?

The tape is designed for direct outdoor application; covering existing tape may reduce adhesion and reflectivity, so remove old layers first.

How can I verify the fluorescent yellow 50 yd roll is performing as intended after installation?

Check nighttime visibility from a distance — the microprismatic material should return bright white light to the source when illuminated.
