| Bonding Polycarbonate / Lexan Windows Into Steel Panels? |
| << < (2/5) > >> |

I did a simple bond test between a polycarbonate off cut and a sample of Zintec that had been painted with the chassis paint I'm using. I used the vinegar smelling version of silicone bath sealant ('acetoxy') and let it set for 12 hours - probably not long enough as it still smelt vinegary this morning - I suspect due to the very small air exposure channel. It worked pretty well - If I still needed to bond the window in the lathe I'd be happy to use it, but I've managed to glaze the door using conventional rubber moulding strip. I did however do a pretty aggressive peel test as per second picture. The bond area is 30 x 80 mm and the lead weight is 3500 grams. It stood the test for a good 25 minutes This "Acetoxy" type of sanitary sealant was what I had to hand, but reading up on it is is not the best for bonding polycarbonate, however in this application I think that it would have been fine. |

I use acetone to weld poly together but I don't think that would make it stick to steel. To weld poly pieces together just clean the pieces well and then dribble a little acetone on the poly and put the pieces together and let set for a few hours. |

This will glue it to itself & steel, best all around adhesive I've found http://www.sashco.com/products/through-the-roof/ |

Hi flylo welcome to the forum. Would you like to post in the Introductions section to tell us all about you? |

I have used clear 3M VHB tape for this purpose before. It was very easy to apply and worked extremely well but was a bit expensive compared to other glues. |
