Problems solved by technology

[0005] The problem with existing methods is that a primer is required to create a strong bond between the adhesive and the enamel on the glass
Also, the need for high temperatures to cure the ceramic paint is undesirable
In addition, the inorganic ceramic coating fused to the glass makes it difficult to recycle the glass when defects develop during glass production or at the end of the vehicle's life

[0132] Use the following sequence of component additions: isobornyl acrylate (GENOMERTM 1121, Rahn); 12.70 g, Tripropylene glycol diacrylate (TRPGDA TM , UCB), 6.00 g, acrylic acid (from Acros Organics), 5.34 g, tetraethyl orthosilicate (SILBOND TM pure, SILBOND), 5.00 g, polyether-modified polydimethylsiloxane (BYK TM UV3510, BYK-Chemie), 0.36 g, polymerization inhibitor (ADDITIVE TM 01-468, Rahn), 0.50 g, polymeric dispersant (SOLSPERSE TM 32000, Avecia), 2.20 g, and aliphatic urethane acrylate oligomer (CN TM 985B88, Sartomer), 21.10 g. The components were added to a "Max 60 cup" from Flack Tek and mixed using a Hauschild Speed ​​Mixer (DAC 150FVZ-K) at 1000 to 1500 revolutions per minute (RPM) for 4 minutes. This mixing process was repeated for an additional 4 minutes to ensure a homogeneous formulation. The homogeneous formula was then poured into an 8 oz (237 ml) plastic NALGENE TM bottle, then add 11.00 g of carbon black pigment (MOGUL TM E, Cabot) and 32.02 gra...
