Natural Wood Veneer Aluminum Profile PVC Wood Film Aluminum Square Tube Exterior Panle Floor

Fields of application:

For highly durable in bonding of:

• Wood based materials for in terior area

General edge banding in the furniture industry

PVC and wood based profiles with:

• PVC foils
• CPL, thick decor paper
• Veneer

Yellow chromated aluminium profiles

For interior finishing of motor vehicles:

• lamination of cloth/carpet or PVC foils to substrates made from wood based materials or plastic
• 

Advantages:

• Very high green strength with high tack
• Heat resistance more then 150 °C
• Cold resistance up to -40 °C

Application techniques:

PUR- hotmelts react with ambient air humidity. KLEIBERIT PUR-HM 702 is available in tightly closed metal containers suitable for platen melters. The package should only be open immediately before use.

The melting equipment must constructed in such a way that the adhesive is protected from ambient air humidity. It is important that the temperature can be controlled accurately.

Yellow chromated aluminium profiles must be preheated to approx. 40 °C immediately before bonding. The chrome coating must not be older then 4 weeks.

The application temperature for profile wrapping is from 140 °C to 160 °C. For edge banding the application temperature is in the range from 120 °C.

(veneer and resin paper can have higher application temperatures)

The required coat weight depends on the material: E.g. Profile wrapping:

-PVC-Foil 40 - 60 g/m²

• Decor papers

(Incl. CPL-Material and thick papers) 50 - 70 g/m2

• Veneers 80 - 120 g/m2

E.g. Edge banding onto:

• Particle board and MDF from 140 g/m2

• g/m2

Properties of the adhesive Basis: Polyurethane

Specific gravity: approx. 1.04 g/cm³

Viscosity (on the day of production) -Brookfield HBTD 10 rpm (mPa.s):

The speed, depending on the materials and the profile geometries used, is between 10-60 m/min and can be even higher. The final bond strength is reached after approx. 7 days.

Chemical cross linking of PUR hotmelts requires moisture. Therefore sufficient air humidity has to be present during processing.

Application equipment:

• Cartridge guns for manual use
• Tank melter with nitrogen blanket
• Drum melting systems for 20 and 200 litre drums
