503 Compound Adhesive (PVC/PET)
503 is the special double-component polyurethane adhesive for compounding of PVC film. Because of its high permeability to PVC, it is especially suitable to bond for PVC film with polyester (PET), polyethylene(PE), polypropylene (PP, CPP, BOPP) and polyamide (PA) film that the surface activation has been treated. It is notable feature that no need to surface treatment of PVC film before bonding. Compound product coated with the adhesive is characterized by excellent strong adhesion, high transparency, good aging resistance, good solvent resistance, non-toxic and odorless.

Process conditions
1.The adhesive should be coated on PET film or other films only. (note: not coated on PVC film which is for the cover film only.
2.The amount of coated adhesive:coating amount(dry basis) can be chosen from 3.0g/ ㎡ to 5.0g/ ㎡, depending on the requirements.
3.Temperature of Drying Tunnel:first stage:50℃;second stage:60℃;third stage:70℃.
4.Hot-pressing temperature:60℃ above.
5.Curing condition:put it in 40℃-50℃,or keep it for 24~48 hours at normal temperature.
Cautions
1.Can’t be mix with other Adhesives.
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 within 5 hours after it is ready-made. If continuing to use the remain, first mix the remain and the new formulated glue together, and then the mixed glue should not exceed 5 hours. (if exceed, solidification is likely to come out)
4. The process ratio in this paper is for 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.
