TECHNICAL DATA SHEET
DENDRITE OR-3000 (M)
Product / : Solvent borne Polyurethane adhesive.Appearance / : Slight hazy liquid.
Viscosity at 30 ± 2°C / : 1500 – 1650 cps for summer
1200 – 1400 cps for winter
Solid Content / : 15.0 – 15.5%
Specific Gravity / : 0.85 – 0.87
Diluents / : Acetone
Application Method / : It is mandatory to use the adhesive mixed with cross linking agent like Yamadur H – 20 / Yamadur R – 22 @ of 5% by weight in order to attain better durability of bonded surfaces & resistance to higher service temperature. The bonding surfaces should be free from dust, oil and grease and if required, suitable primer should be used depending upon nature of the substrates. This primer should be dried before application of adhesive. A thin layer of hardener mixed adhesive is to be applied on the surfaces to be bonded. Allow 15 to 20min for solvent evaporation. Tack – free adhesive films on both substrates are to be heat activated at around 55-60ºC and then pressed together with adequate uniform pressure. Final peel strength will be achieved after 24 hours.
Coverage / :
Advantages / : High hot tack, required low heat activation. Good initial gripping.
Usage / : This adhesive very suitable for synthetic upper where low heat activation is required. It is also used for bonding different footwear substrates like leather, PVC sole, TPR sole, EVA etc.
Storage / : Store in a cool & dry place, keep the container away from heat, direct sunlight & naked flame.
Precaution / : Close the lid tightly after taking out required material from container.
Shelf life / : 9 months from the date of manufacturing under proper storage condition.
