I got some UV resin and UV flashlight. These were for experiments so I opted for the cheaper ones. The resin was from China and took a month. This stuff is clear and consistency of thin syrup. The catalyst is the certain UV wavelength and while the flashlight provides this so does the sun. When doing this I would add some and then walk out of the garage into the sun. Drips would stop and the stuff would heat up and harden. It takes about 5 seconds of light to change from liquid to solid and 10 sec to get hard.
Its used alot in crafts and while interesting I had in mind trying to salvage a 69 washer bottle I had. I first tested it as a glue on 2 black plastic parts but if the light does not penetrate it wont cure. It needs light so you cant drop it into a hole and hope it will harden. However the washer bottle will let light thru so I wanted to give it a try. This bottles was especially crappy as it was hit with acid and lost a big piece of it neck and turns black. It had 2 holes in the lower corners and had stress cracks almost everywhere. As I poked around the cracks I knocked more off. Dumb ***.
It was too delicate to clean right away so I added a few drops around the holes and 5 sec later it was solid. I added a few more drops and spread it out with my finger. That turned solid too. Let me explain that while it was solid it was still sticky on top. I found out its a problem with using some cheap resin and relates to curing too fast. Anyway, its fine but tacky/sticky on top but NOT soft at all. Just the surface. After solidify around the whole I added a pieces of clear saran wrap around the hole. It stuck to the stickiness. I dropped some in from top and moved it to the plastic wrap and hit it with light from the outside. Solid and completely filled the hole. It had ripples because the plastic was thin and as it cured the heat distorted the plastic. I found out later the packing tape worked better. The plastic wrap peeled right off. I did this to all the holes and the damaged neck. I'm not done the neck but I added some window screen to form a better mouth then tape could do. I also made replacement mounting tabs. Strong enough to hold the bottle by.
After doing the outside it was very sturdy and handles just fine. Nit brittle. I then put some resin inside and moved it around and back in the sun. This penetrated the hazy bottle and it solidified in 15 min. At 2 min it stopped moving around the bottle. Of course the big question is will it hold alcohol washer fluid. Now that the inside is done I will test this. I think it will but if not I may just buy some fuel tank liquid liner and add it to the inside. I think the resin was $15 (200g) and light was $5. Also i have to address how it looks. Its butt ugly - franken bottle. Because its clear you can see all the ugliness. And its tacky. After sanding I think some creamy paint will fix both. I'm not after white -
like new.
