just need to share some experience with lami glass procesor about pvb film.
i ve been using dupont pvb for the past 12 years and no quality issues about it. howver recently there are alot of chinese pvb maker which offers superlow prices.
i have tried and the result seems to be ok..but not sure about long terms, ie after the glass has been on the road for more than 12 month.
any experience from anyone on this issue is welcome..
