EVA Film FAQs

Q.
Why might glass not stick properly during lamination?

A.
This can happen due to several reasons, such as insufficient processing temperature which leads to an incomplete reaction of the EVA film, resulting in weak bonding force. It could also be due to the glass being too thick compared to the thin EVA film used, or excessive humidity which can dissolve the crosslinking agents within the EVA, reducing its adhesiveness.
Q.
How can I ensure the best adhesion when laminating glass?

A.
Ensure that the processing temperature is appropriate for the EVA film used, and that the glass thickness is compatible with the film. Also, store the film in a dry place to prevent the negative effects of humidity.
Q.
What should I do if I find bubbles in the middle of laminated glass?

A.
Extend the lamination time appropriately to allow for complete air discharge. Also, ensure that vacuuming is stopped when the temperature is below 60°C to prevent air from flowing back into the glass.
Q.
What factors can reduce the transparency of laminated glass?

A.
The presence of moisture on the EVA film and insufficient processing temperature, which leads to an incomplete film reaction, can both decrease transparency
Q.
How can I improve the transparency of my laminated glass?

A.
Store the film in a dry place to avoid moisture-related transparency issues and ensure that the processing temperature is adequate for the EVA film to fully react.

Q.
What is the ideal processing temperature for laminating glass?

A.
The ideal processing temperature varies depending on the specific EVA film used. Always refer to the manufacturer's guidelines for the recommended temperature.
Q.
How should I store EVA film to maximize its performance?

A.
Store the EVA film in a dry, cool place, away from direct sunlight and moisture, to maintain its adhesive properties and prevent degradation.
Q.
How does humidity affect the glass lamination process?

A.
You can send an email to sales@johnshen.com.cn to require a quotation. And we will have a salesman corresponding to the market contact you asap. And it will be appreciated if you can provide us your company basic information, market, and company type.
Q.
How does humidity affect the glass lamination process?

A.
High humidity can dissolve the crosslinking agents in the EVA film, leading to reduced adhesion and potential delamination. It's crucial to control the humidity during the lamination process and store the film in a dry environment.
Q.
What should I do if I suspect my EVA film is affected by humidity?

A.
If the film is suspected to be affected by humidity, it is advisable to replace it with a new, dry film to ensure proper adhesion and transparency.

Q.
How can I tell if my laminated glass has insufficient transparency?

A.
Inspect the glass for any haziness or cloudiness that was not present before the lamination process. Compare it with a standard or sample to identify any significant differences in transparency.
Q.
Is there a way to salvage laminated glass with poor transparency?

A.
If the transparency is compromised due to moisture, you may be able to salvage the glass by removing the film and reapplying a new, dry one. However, if the issue is due to insufficient processing temperature, the glass may need to be relaminates with proper temperature control.
Q.
How long does it typically take for bubbles to form in laminated glass, and can they be prevented?

A.
Bubbles can form immediately after lamination if the process is not correctly followed. By ensuring proper temperature control and vacuuming procedures, you can significantly reduce the risk of bubble formation.
Q.
What are the consequences of using glass that has not been properly laminated?

A.
Improperly laminated glass may have reduced structural integrity, lower insulation properties, and poor aesthetics due to issues like bubbles and lack of transparency
Q.
Can I perform glass lamination myself, or do I need professional help?

A.
While it is possible to laminate glass with the right equipment and knowledge, it is often recommended to seek professional help to ensure the best results and avoid common issues like poor adhesion and bubble formation.
