This product has all the characteristics of the 3000 Series, but is designed to hold up to twice the over-spray before changing is required. This double service life makes this series ideal for high production applications wherever a large volume of coating is applied in a relatively small booth space. This longer service life results in less down time, fewer changeovers and greater economy. Rolls or pads are used in tandem. The product is ideal for heavy, tacky coatings or slower drying finishes, but is not recommended for quick dry lacquer type coatings.
