De-lamination Solution of Processing Laminated Glass With EVA Film
By Peter Lin

De-lamination:

1)- The heating temperature is not high enough or the heating time is not long enough for the EVA FILM to melt and react totally, so the cross link reaction is not finished.
For this reason, please increase the heating temperature or prolong heating time of laminating.

2) -The EVA FILM is out of the shelf life, most EVA FILM’s self life is about one year or longer. Please use the EVA FILM within the self life. Yes, different EVA FILM manufacturers may have different self life for the EVA Film.

4)-Maybe it’s the problem of the quality of the EVA FILM. Send some film samples back to the EVA FILM manufacturer to test the EVA FILM again.

5)-The moisture of the glass or EVA FILM before lamination is too much. EVA FILM are less sensitive to moisture, but if it’s too high, it will do harm to the adhesion of EVA FILM. Please dry glasses and store EVA FILM in good way.

6)-There is some organic substance on the surface of glasses. For example oily substance will also do harm to the adhesion of EVA FILM.
Please clean the glasses if necessary. You can use clean water, industrial alcohol, Acetone to clean the glasses.

7)-When laminated with the painting papers (like PP, PVC), the printing ink is too much and not being dried.
Please dry the printing papers first before laminating with glasses and EVA FILM.

8)-If you found the de-lamination is happening in the edges of the laminated glass, maybe the workers’ hand touch the edges of the glasses, and there are oily substance in the hand, which will do harm to the adhesion of the EVA FILM.
Please ask your worker to wear gloves. And maybe its summer, and your workers work very hard, and their hands are sweaty. And the sweat will do harm to the EVA FILM.

9)-If the de-lamination happens after installation in to buildings, please remember to check the glass sealant that you use. The glass sealant should the the neutral types.

Standard Fixed Width120cm*Any Length
Standard Fixed Width150cm*Any Length
Standard Fixed Width180cm*Any Length

How To Calculate the Square Meter Quantity?
We use Standard Fixed Width to cut the right size as clients require.The quantity is based on how big of the standard size we need to cut the right size.

Example 1, if you need 110cm*80cm, we will use 120cm*80cm to cut the right size of 110cm*80cm and a waste of 10cm*80cm, so the amount will be calculated based on 120cm*80cm. And if you want, you can take all the smart films (the right size of 110cm*80cm and a waste of 10cm*80cm).

Example 2, if you only need 50cm*50cm, we will use 120cm*50cm to cut 2 pcs of 50cm*50cm and a waste of 20cm*50cm, and you will have to order 2 pcs of 50cm*50cm together at the same time, and the amount will be calculated based on 120cm*50cm. And if you want, you can take all the smart films( 2 pcs of 50cm*50cm and a waste of 20cm*50cm).

Example 3, if you need 170cm*130cm, we will use 180cm*130cm to cut the right size of 170cm*130cm and a waste of 10cm*130cm, so the amount will be calculated based on 180cm*130cm. And if you want, you can take all the smart films(the right size of 170cm*130cm and a waste of 10cm*130cm).

Electrical Transformer
Optional; Clients can offer the Electrical Transformer by themselves.

Notes:
*If you are not experienced, it’s better to let us assemble the electronic connector(busbar) for you.
*To protect the smart film, we suggest shipping by air or by express, like DHL, FEDEX, UPS, etc.
*The weight of smart film for shipping will be calculated by Dimensional Weight, because the package is light, but bigger in dimension.
