1. Product Overview
tesa® 4244 PV0 is a flexible fineline masking tape made of soft PVC film with a natural rubber adhesive. It is designed for applications requiring extremely sharp paint edges, particularly on painted or unpainted plastic parts and in multi-colour painting. The tape offers high conformability to multi-dimensional surfaces, resists shrinking at elevated temperatures, adapts to dimensional changes during oven-drying, and can be removed cleanly without leaving residues.

2. Applications

  • Fineline masking for sharp paint edges

  • Multi-colour painting processes

  • Use on painted and unpainted plastic parts

  • High-temperature painting processes with oven-drying

  • Converting and die-cutting (also available as tesa® 4244 PV4 with paper liner)
