Why is UPVC Profile coated?

Why is UPVC Profile coated? Because the strength of doors and windows processed with PVC profiles alone is not strong enough, in order to strengthen and consolidate, steel will be added to the cavity. Therefore, plastic doors and windows made by adding steel to the profile are usually called UPVC Profile. With the widespread use of plastic steel doors and windows, the PVC profiles used to make plastic steel doors and windows are customarily called UPVC Profile. So why is UPVC Profile coated? Lumei Construction Material Co., Ltd. will share with you:

First, the reason for UPVC Profile coating

1. Aging of UPVC Profile

After being exposed to strong light and rain, white things will appear yellow on the surface after a period of time, which will appear dirty and old, which will affect the aesthetic effect. The point is that this will cause the aged material of the profile to become brittle and reduce the hardness of the profile. Mainly manifested in PVC doors and windows in the family.

In response to this defect, color window films have appeared on the market. The window film coated on the surface of the PVC profile can largely resist the invasion of the PVC profile of doors and windows by the high temperature of sunlight, protect the material of the plastic doors and windows, and prolong the use time.

2. Personalized needs

The use of decorative film on the surface of UPVC Profile packaging can meet individual needs.

Second, the process of coating:

There are several processes to realize the beautification of plastic and aluminum alloy doors and windows, such as spraying, thermal transfer, color full-body, and color co-extrusion. But there is still no way to solve the problem of weather resistance of doors and windows. The emergence of UPVC Profile laminating process properly solves this problem and meets individual needs.

To put it simply, a film with extremely high weather resistance is passed through a profile coating machine, and an adhesive is added to coat the surface of the PVC or aluminum alloy profile. After the film is coated, the profile can be cured for a certain period of time, and then the secondary processing can be carried out.
