PU 70
Description
Zettex PU 70 is a permanently elastic, one component windshield adhesive based on polyurethane. Zettex PU 70 is an extremly powerful adhesive for adhering most of the surfaces used in the marine, offshore, aviation, truck and trailer industry.

Chemical nature

Polyurethane

Advantages

• One-component Polyurethane
• Suitable for cold application
• Good stability/workability – non sag
• Short cut-off string
• Suitable for use with integral aerials.
• Prevents contact corrosion in aluminium-body vehicles.
​Packaging
• Cartridge 310ml
Application
• ZETTEX PU 70 is a versatile elastic Polyurethane based Adhesive for the bonding of front, side and rear glasses used in Commercial/Industrial vehicles. Suitable for elastic structural bonding (assembly of various materials which are subjected to high thermal and dynamic stress) in the Transportation Industry.

• Fit the cartridge into a manual or pneumatic air operated gun (provided with telescopic piston). 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.
