PRODUCT DESCRIPTION
tesa® 4959 is a double-sided non-woven industrial mounting and splicing tape with a highly tackified acrylic adhesive. The premium non-woven tape is, for instance, used for mounting signs and nameplates or other mounting and high-performance lamination applications. tesa® 4959 is especially designed to connect flexible materials to one another. The mounting and splicing tape is able to withstand numerous environmental factors such as humidity, UV light, and temperatures of up to 200°C for limited periods of time. The tackified acrylic adhesive offers excellent hold on various surfaces, very high tack, and good shear strength. The adhesive is coated on a flexible and conformable cellulose non-woven backing that even conforms to difficult 3D shapes.
FEATURES of tesa® 4959
- Skin contact certification according to ISO 10993-5 and ISO 10993-10
- Reliable bond, often also on low surface energy surfaces
- Light and aging-resistant acrylic adhesive for long-term applications
- Excellent initial tack and peel adhesion
- Good converting and die-cutting properties
- Highly conformable to follow difficult 3D shapes due to non-woven backing
APPLICATIONS of tesa® 4959
- tesa® 4959 is ideally used for industrial mounting, high-performance lamination, and splicing applications
- Mounting signs, covers and nameplates
- Laminating insulation materials and foams for HVAC (heating, ventilation, and air conditioning) seals
- Mounting plastic bags, dispatch bags, continuous stationery, posters, etc.
- Splicing of paper and film webs
