Waterborne polyurethane adhesive technology（TDS）

Product description:
This series of aquatic glue is water-based polyurethane (PUD) adhesive is one of the system.
Introduce hydrophilic group into polyurethane polymer modified copolymerization after finished glue, colloid has: water-based environmental protection, high efficiency spraying, early quick-drying glue, strong adhesive force, high solid content, good with hot, waterproof, applicability is wide and its superior performance, etc.
                                                                              
Product use:
Widely used in all kinds of tangible parts of the vacuum thermal compound, such as polyvinyl chloride (PVC materials such as software and density board, particle board, wood, etc. The vacuum.
Vacuum forming, it is mainly used for wooden door, cabinet, speakers board vacuum salt forming, computer desk, etc.Applicable to chemical fiber products, non-woven fabrics, leather/PVC leather joint, such as auto interior materials bonding.
                                                                               


Product features:
Colloidal environmental non-toxic, no smell, quick drying, strong initial adhesion, high adhesion strength, good heat resistance, with strong stability, excellent words without pitting.
Cooperate with curing agent using a sticky point strength, high heat resistance, water resistance and anti-aging.
Colloid high solid content, after curing, waterproof moisture-proof, action syndrome and resistance against shrinkage open border foaming, adhesion after frozen resistance heat resistance, no grade a.                                                                                                                                                                                                                             
Operating instructions
1, the main agent and curing agent ratio of main agent: curing agent = 100, 5 (weight ratio).
2, base material moisture content: 8-12%.
3, compound ways: dry.
4, resin content: plane 6570 g/m2, edge and recessing area is about 80100 g/m2.
5, the drying time: spray adhesive to the base material, after about 30 minutes after the start, when the room temperature is 25 ℃ C blister.
6, activation temperature;55 to 60 c.
7, operating temperature: 100-160 "c (should be according to the environment temperature and the thickness of the leather, base material complex appropriate adjustments).
8, pressure pressure: 0.40.6 MPa.
9, suck at pressure time 25 to 50 seconds (should be according to environment temperature and the thickness of the leather, complexity of base material appropriate adjustments).
10, furnishing health 24, 72 hours after unloading;(specific operations must be adjusted according to actual situation


Storage: room temperature storage period is 6 months, smothering high temperature rise will make storage Yang shorten.Winter storage temperature should not be less than 8 ℃ C, in order to prevent freezing.
Packing/net weight: 20 kg/plastic drum, 200 kg/iron drum, 1000 kg/plastic drum
