DINITROL 410 UV black one-component adhesive 600 ml

Description

DINITROL 410 UV NF is a one-component polyurethane adhesive and sealant that cures with atmospheric moisture. It cures quickly, stays flexible and has high resistance to UV radiation and weathering.

It is used in bus, truck and caravan building and in boatbuilding — for bonding and for sealing overlap and expansion joints, inside and outside.

No primer needed on many substrates

It adheres well to primed and painted metals, GRP, rigid PVC, wood and glass — and on many of these it needs no adhesion promoter. That saves you a work step, waiting time for the primer to dry and material costs.

On more demanding substrates, always test adhesion on a small area first.

Painting

Once cured, it can be painted with most paints. 2K acrylic paints can also be applied wet-on-wet, so you do not have to wait for the sealant to cure fully.

Beware of paints containing alcohol or alkyd resin

These paints prevent the sealant from curing. Always check the paint composition before painting and test on a small area.

Resistance of the cured joint

The cured material resists water, salt water, dilute acids and alkalis, and water-based cleaning agents. It also withstands petrol, greases and mineral oils for short periods.

The temperature range is −40 to +90 °C, and up to 120 °C for short periods.

Surface preparation and application

• The surface must be clean, dry and free of dust, oil and grease. Clean contaminated substrates with DINITROL 582
• Insert the foil pack into a gun designed for sausage packs and cut it according to the gun instructions
• Work with the material at room temperature. Application temperature +5 to +35 °C
• A skin begins to form after 30 minutes and the surface is touch-dry after approximately 2.5 hours
• Remove uncured material with white spirit. Once cured, it can only be removed mechanically

What you will need

For the foil pack, you need a gun with a sufficiently long barrel — choose one in the application equipment category.

Products for cleaning the substrate and removing fresh residue are in the surface preparation and cleaning and wipes categories.

Wear nitrile gloves and eye protection — the material contains isocyanates.

You will find more sealants in the sealants category and adhesives in the structural adhesives category. Materials for caravan building are in the caravan building category.

FAQ – Do I need to use a primer before bonding?

On many substrates, no — that is the main time saving compared with other polyurethanes. On more demanding or unusual materials, test adhesion on a small area first.

Why did the sealant not cure under the paint?

Most likely because of a paint containing alcohol or alkyd resin — these prevent curing. 2K acrylic paints do not cause this problem and can also be applied wet-on-wet.

Can an exterior joint withstand sunlight?

Yes. The material has high UV stability and weather resistance, so you can leave it exposed on visible exterior joints.

How do I remove excess material?

Wipe off fresh material with white spirit. Once cured, it can only be removed mechanically, so it is best to mask the area around the joint beforehand.
