Product Description

504 laminating Adhesive (Metal/PET)
 
    504 isa two-component special polyurethane laminating adhesive for lamination of metal. Because of its strong adhesion to metal, it is especially suitable for bonding of metal coils (aluminum foil, iron coils and others) and polyester (PET), polypropylene (PP, CPP, BOPP), polyamide (PA) film that surface activation has been treated. Clean the surface of metal coils before bonding. Compound product coated with the adhesive is characterized by excellent strong adhesion, high transparency,excellent aging resistance, high temperature resistance,excellentsolvent resistance, non-toxic and odorless, and it can beboiled at 120℃ also.

    It is advised to use this ratio, which is 10:5:2 first. You can adjust it appropriately depending on requirements.

 

Process conditions

1.The amount of coated adhesive:coating amount(dry basis) can be chosen from 4.0g/ ㎡ to 5.0g/ ㎡, depending on the requirements.

2.Temperature of Drying Tunnel:first stage:50°C; second stage:60°C; third stage:70°C;fourth stage:90°C

3.Hot-pressing temperature: 90°C~100°C.

4.Hardening condition: keep it at 50°C~60°C for 24~48 hours.

 

 

 

Cautions

1.Cant be mix with otherAdhesives. 

2. To avoid turbidity, please clean all equipment, including plastic tank, buckets and relevant tools before using the adhesive.

3.The formulated glue should be used up within8 hours after it is ready-made. If continuing to use the remain, the mixture of the remain and new formulated glue together should not exceed 8 hours.(if exceed8 hours,solidification is likely to come out)

4. Theprocess ratio in this paper isfor reference only.Due to different manufactures are with different technology conditions, raw material conditions and equipment conditions, we recommend that manufactures confirm the pre-tests or consult with us before using. Our products are only sold according to general condition.

5. According to customer demand for products, we can make the overall design of the program, including modifying the product formulation and setting the process methods.

Quality index of compound iron sheet

Salt resistance:intrude it into solvent(concentration :5~8%) for 3 days.Two film still keep sticking together.

Hot water resistance:intrude it into hot water(temperature: 80°C~100°C) for 30 minutes.Two film still keep sticking together.

Alkali(NaOH) resistance:intrude it into solvent(pH=13,concentration:0.1mol/L) for 5 hours. Detect it with pH test paper.

Acid(H2SO4) resistance:intrude it into solvent(pH=1,concentration:0.5mol/L) for 24 hours.Detect it with pH test paper.

 

Requirements for product

Boil it in 120°C,and two film still keep sticking together in 45 minutes.
