DINITROL 501FC polyurethane adhesive 310 ml

Description

DINITROL 501 FC is a one-component polyurethane adhesive that cures with atmospheric moisture. It is designed for direct glazing of automotive glass and other bonded joints in vehicle manufacturing.

It cures quickly, adheres well to paint, has a low odour and high elasticity. It contains no solvents or PVC and resists ageing and weathering.

Safe drive-away time

A vehicle without airbags can be handed over after just 1 hour, a vehicle with passenger airbags after 3 hours — Safe-Drive-Away-Time according to FMVSS 212/208.

The values apply at 23 °C and 50 % relative humidity. In a cooler or drier workshop the time is longer.

Surface preparation

The bonding surface must be clean, dry and free of dust, oil and grease.

Thoroughly clean the ceramic edge of the new glass with DINITROL 582 Special Cleaner, which removes stubborn contamination from both the glass and the ceramic frit.

Depending on the system, this is followed by an activator or primer — for example DINITROL 520 KLEENACT or DINITROL 530 PRIME B. You will find the full range in the surface preparation category. Follow the glass replacement procedure and the pre-treatment table.

Glass without a ceramic frit or equivalent protection needs additional UV protection.

Application

• Apply the adhesive with a sufficiently powerful caulking gun
• Work with the adhesive at room temperature — it is much easier to apply. Product temperature during application 15–35 °C
• Apply a triangular bead so that the adhesive layer has an even thickness
• Fit the glass before a surface skin starts to form — within approximately 15 minutes
• Heat and higher humidity shorten the open time, cold and dry air extend it

What you will need

To dispense the cartridge, use the pneumatic and manual guns from the application equipment category. For frequent work a pneumatic gun is worth it — it doses more precisely and the bead is more even.

For removing the original glass and old adhesive residue, you will find cut-out wires, knives, scrapers and dashboard protectors in the auto glass tools category.

Wear nitrile gloves and respiratory protection — the adhesive contains isocyanates.

Which pack size to choose

The 310 ml cartridge fits a standard cartridge gun and suits individual glass replacements. For higher volumes, choose the 400 ml or 600 ml foil pack — these need a gun designed for foil packs but produce much less waste.

FAQ – When can I hand the vehicle back to the customer?

A vehicle without airbags after 1 hour, with passenger airbags after 3 hours. The values apply at 23 °C and 50 % humidity — in cold and dry conditions the time is longer.

Which cleaner, activator or primer do I need with it?

It depends on the substrate and whether you are bonding to glass, ceramic frit or paint. The products are not interchangeable — always follow the pre-treatment table for the specific substrate. You will find the full range in the surface preparation category.

Why does the adhesive set faster than last time?

The adhesive cures with atmospheric moisture. In a warm and humid workshop a skin forms sooner and the open time is shorter, while in cold and dry conditions it is longer.

Why a triangular bead?

It ensures an even adhesive layer thickness around the entire perimeter of the glass. With an irregular bead, the adhesive would be thinner in some places and the joint would not have uniform strength.
