Main Agent Composition: Thermoplastic Resin
Promoter Composition: Flexibilizer
Bonding Function: Structural Adhesive
Application: Automobile, Construction, Woodworking, Footwear & Leather, Fiber & Garment, Packing
Classification: Hot Melt
Composition: Organic Material
Envirnment Proof: Reactive
HS Code: 35069190
Rohs Approved Reactive hot melt adhesives(PUR)
Pur melt 9305
APPLICATION: Bonding of leather, wooden material, metal, glass, textiles, PUR-foams, numerous membrane
films and plastics like PVC, ABS, PC etc.
Properties Pur melt 9305 has middle open time and bonds fast.
After curing there is high cold and heat resistance. Bonding are resistant to water and fairly good to solvents. The cured bonding has high mechanical properties.
Technical Data: Base: Polyurethane-based reactive hotmelt

Melt Viscosity (Brookfield Thermosol-SP 29) at 160oC: approx. 15 000-25000 mpa.s
Application temperature: 160-175 oC
Bond Strength: 2-8 N/ mm2,
(Testing of tensile transverse depending on substrates (break materials)
Resistance-beech wood sheets 100*20*5mm)
Working time: 3-5 minutes@25oC
Storage life: approx. 9 months
Sensitive to cold: no
Sensitive to humidity: yes
Instructions for Use:
The surface of the substrates must be clean dry and free from oil and grease. The temperature of the substrates must not be below 20 oC during coating as lower temperature deteriorate spreading of glue and shorten open time.
Metals should be heated to about 40oC to get better adhesion.
After physical curing, bonded parts are quickly ready for further processing.
The adhesive can be applied by nozzle, roller and spray equipment.
As a matter of principle, care has to be taken the melting and application equipment is protected against incoming moisture. This can be reached by applying dry nitrogen or dry air.
Final strength is achieved after 5-7 days depending on availability of moisture and temperature.
Remarks: Please care for exhaust of vapors occurring during application.
Advice: For cleaning of melting and application equipment from not cured adhesive, we offer CLEANER JL-CA101-blue; Cured adhesive can only be removed mechanically.
