We have received your information , thanks again, do you think that bonding
with optical cement can be an economical solution to produce blocks of lami
nated glass  with a final width of 45 mm  with slices of laminated galss of 4 ,
6,
and  8 m.m..

Some people has recommend to use  a resin radcured name UVEKOL from
a belgium company  UCB.What do you think about this  ?
