Paint masking tape 4330

high temperature-resistantfor automotive applicationsfor precision work

Short description
Paper masking tape for paintworks with oven-drying up to 140 °C, combining a fine crepe paper backing with a temperature-resistant natural rubber adhesive.

Sustainable Aspects

• 48% bio-based content in total product excluding liner (by weight).

Product Features

• Fine crepe paper backing paired with a high-adhesion, temperature-resistant natural rubber adhesive.
• Suitable for demanding automotive paint jobs with subsequent oven-drying up to 140 °C (water- or solvent-based paints).
• High tack and reliable adhesion to substrates such as paint, metal, glass, rubber and plastic.
• Paint and filler systems adhere well to the reverse side, minimising flaking.
• Excellent conformability for precise cornering and edge definition; good hand-tearability and clean removal.

Application Fields

• High-requirement automotive painting and general industrial paint masking with oven-drying cycles up to 140 °C.
• Masking on substrates including painted surfaces, metals, glass, rubber and plastics.
• Corner and edge masking where conformability and reverse-side anchorage of paint/filler are required.
• Masking of circuit boards prior to plating and other process masking applications.
