Bonding PlasTeak

[noelH]

Stern end of the PlasTEAK trim needs repair and attention.  Starboard side has had or developed a crack on one side. Port side cracked develop on both sides of the screw by the end of last season. Noticed a slight crack on the port side a couple seasons ago. Same location.  Right where the last screw is attached. Didn't take much to totally crack off the port side today while getting Vela ready for the season.

PlasTEAK websites notes "nothing sticks", "cannot be glued..." But then they sell an adhesive to bond the deck and flooring products.  Comes in a glue "sausage". SDS sheet notes it is Lonseal 2 part epoxy.  Plan is lay down a thin coat of bedding on the broken off side and just try Loctite Plastic Bonder or a similar product applied to the break and squeezed into the crack.  Bad idea?

Update.  Internet searching.  PlasTEAK is a "low energy" plastic.  Basically like M to HDPE. So far, the only products I can find that don't require some sort of surface treatment are PermaBond TA4611 and TA4631.  "Structural acrylic polyolefin bonders".

What about plastic welding it back together...  break it off the rest of the way, heat it up with a torch, press it back together, and sand off the squeeze out?

Well, maybe the situation is trying to tell you that material isn't the best application for THAT place. Too, plastic will change it's properties with exposure to light. Direct sunlight is much more degrading. It's always something.
