Tesa® 4329 crepp 50mm x 50m

tesa® 4329 PV1 crepp

Finely creped paper mask tape

tesa® 4329 is a slightly creped, easy-to-use paper mask tape that is suited to a wide range of uses. It is often used by craftsmen for carrying out varnish work, in order to safely and reliably protect individual car or motorbike components. This mask tape is watertight, resistant to temperatures of up to 70 °C and bonds with both varnishes and fillers. Thanks to the adhesive strength of its natural rubber mass, this mask tape ensures a good adhesion on various surfaces and enables precise edges during varnish work.

Processing and storage information
Surface condition
Surfaces must be dry, free from dust, oil, oxides, release agents and other contaminants.

Surface cleaning
The following cleaning agents, for example, can be used to remove dust, oil, separating agents and other impurities:

Isopropanol/water 50/50
Heptane or ethanol
Acetone or MEK
Suitable other cleaning agents that do not leave any residues and do not attack the substrate.

Temperature
The most favourable processing temperature (object and ambient temperature) is between +15°C and +25°C.

Pressure
The strength of the bond is directly dependent on the contact that the adhesive has with the surfaces to be bonded. A short, high pressure (e.g. with a squeegee, pressure roller or pressure device, etc.) ensures good surface contact. The type and amount of pressure depends on the material (thin- or thick-walled, etc.) and the geometry of the components. Rule of thumb: approx. 20 N/cm².

Storage
The rolls should be stored in their packaging protected from light at a temperature between +15°C and +25°C and a relative humidity of 50%.
