DENDRITE OR 3000 M PU
- Base : Polyurethane Adhesive.
- Application : 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.
- Solvent : This is composed of Ketonic and aromatic solvent combination.
- Colour : Slight hazy liquid.
- Viscosity : 1500 – 1650 cPs for summer at 30 ± 2°C,1200 – 1400 cPs for winter at 30 ± 2°C.
Method of Application
- It is mandatory to use the adhesive mixed with cross linking agent like Yamadur H – 20 / Yamadur R – 22 @ of 3-5% 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 for 45 – 60sec and then pressed together with adequate uniform pressure. Final peel strength will be achieved after 24 hours.
Caution
- It is highly inflammable. Replace lid immediately after partial use. Container should be stored in a cool and dry place. It is suggested to wear suitable protective clothing and safety goggles for protecting eyes while handling.
