tesa® 4378 offers a convenient 3-in-1 system for masking large areas. It combines the slightly creped masking tape tesa® 4309 (natural rubber adhesive), a masking paper border, and a high density polyethylene (HDPE) masking film for ideal protection. This system makes it easy for a single person to cover large areas quickly.
tesa® 4309 is conformable and suitable for spray-painting applications that may require oven drying up to 248°F.
The masking paper border ensures paint absorption at the area closest to the coating spot.
The HDPE film, treated to catch paint, protects against spray particles.
