DINITROL 410 UV grey one-component adhesive 300 ml

Description

DINITROL 410 UV NF is a one-component polyurethane adhesive and sealant that cures by reacting with atmospheric moisture. Once cured, it forms a flexible, strong joint with high UV stability and weather resistance.

It is used in the manufacture and repair of buses, trucks and caravans, in boatbuilding and in other industrial applications. It is suitable for bonding and sealing, including visible joints inside and outside.

UV and weather resistance Also suitable for visible joints exposed to sunlight and outdoor conditions.

Permanently flexible joint The cured material remains elastic and can absorb movement between the bonded parts.

Wide-ranging adhesion Adheres well to painted and primed metals, GFRP, rigid PVC, wood and glass.

Paintable Once cured, it can be overcoated with most common paint systems.

Bonding and sealing of structural joints

The material is suitable for combined bonding and sealing in the transport and industrial sectors. It is used, for example, for overlap and expansion joints and for visible seals inside and outside commercial vehicles.

Typical applications

• buses and trucks
• caravans and motorhomes
• boat structures
• commercial vehicle manufacture and repair
• industrial bonding and sealing

Which materials does it adhere to?

DINITROL 410 UV NF adheres well to primed and painted metals, thermosets and glass-fibre reinforced plastics (GFRP), rigid PVC, wood and glass.

On many substrates, no separate adhesion promoter is needed. On unknown, mixed or difficult surfaces, however, check adhesion beforehand.

Surface preparation determines joint quality

The surface must be clean, dry and free of dust, oil and grease. On contaminated surfaces, use a suitable cleaning or preparation product for the specific material.

You will find products for cleaning and preparing surfaces in the surface preparation before bonding category.

Application and curing

• Thoroughly clean, degrease and dry the surface
• Apply the cartridge with a standard caulking gun
• Work the material at a temperature of approximately +5 to +35 °C
• Shape or smooth the sealant before a skin forms
• On unknown substrates or for special applications, carry out an adhesion and compatibility test

At 23 °C and 50 % relative humidity, a skin forms in approximately 30 minutes. The curing rate is approximately 3 mm per 24 hours.

Higher temperature and humidity speed up curing, while lower temperature and humidity slow it down.

Painting and paint compatibility

Once cured, DINITROL 410 UV NF can be painted with most common paint systems. Check compatibility with the specific paint system beforehand.

Two-component acrylic paints can also be applied wet-on-wet. Paints containing alcohol or alkyd resins may impair curing of the material.

Resistance of the cured joint

Once cured, the material is resistant to water, salt water, dilute acids and alkalis, and water-based cleaning agents. It also withstands petrol, greases and mineral oils for short periods.
