PU 75
ZETTEX PU 75 is a one-component, high viscosity, flexible and high performance
polyurethane adhesive that cures on exposure to atmospheric moisture to form a tough,
durable adhesive. Completely solvent free it is odorless and also nonconductive allowing the
correct bonding to glass incorporating radio antenna or additional electrical equipment.
Highly resistant to UV irradiation, weathering and ageing.

Chemical nature

• One-component polyurethane
• Suitable for cold application
• High viscosity – high initial tack and non-sag properties
• Short cut-off string
• Suitable for use with integral aerials.
• Prevents contact corrosion in aluminium-body vehicles.
• High UV resistance and colour stability
• Cartridge 310ml
•ZETTEX PU 75 is specifically addressed to the glass replacing and installation of front, side
and rear windshields in the sector of Bus, Truck, Railway and industrial vehicles. Thanks to
its high viscosity it guarantee a very high initial tack and is suitable for the application of
large surfaces glasses typical in the BTR. Suitable for elastic structural bonding (assembly of
various materials which are subjected to high thermal and dynamic stress) in the
transportation Industry. The product is also characterized by a very good UV resistance
and color stability making the product ideal for the sealing of exposed joints, including
joints between lateral glasses. This once cured it provide an excellent semi-matt
appearance for aesthetical purposes.

• The surfaces to be treated should be perfectly clean, dry and free from dust and grease. It is
necessary to apply a Cleaner/Activator and a Primer on glass. The adhesion on normal
vehicle varnishes generally does not require the use of Primer. It is advisable to carry out
preliminary adhesion tests on the support. Specific guidance regarding the use of Primers
may be obtained by submitting substrate samples to our Laboratories.
