Which is the best adhesive to use? 1

[dhollins]

I'm needing some insight on a project I'm working on that requires bonding or gluing a piece of fiberglass mesh insect screen to a custom frame made of 3/4" pvc pipe. I have read many forums that are using a solvent or epoxy type of glue. I need something that sets quick, and will dry clear... and not come undone on hot days like a hot glue gun will do. I have thought maybe some of the pvc snap clamps may work also... no adhesive needed, but have read these do not hold up well on windy days.

Any adhesive specialists out there...your thoughts or ideas would be helpful.

Stretch the screen over the pvc pipe frame, but not too tightly or it will really flex the sides of the frame when you release your stretching tension. Use your hot melt glue gun to lay down a bead of glue, and immediately behind the gun head drag a 90° (sector, segment?, ripped lengthwise for matching I.D.) piece of the same pipe, about 6-8" long so you can hold and move it with the gun, as you progress. You want to press the hot glue through the screen and onto the pvc pipe, to bond the two together. Might work.

Not an expert at glues but I LOVE Hoby-Poxy you can buy at any good hobby shop. It comes as a thin or thick super glue. Lay a bead down and hit it with the catalyst and in less than 5 seconds it is done. Glues anything to anything - like your fingers to your hand.

College age daughter broke the turn signal on her used Honda - the one that controls all sorts of thing. I glued it back together, wrapped the joint with a layer of fiberglass - about 1'' wide and smeared it with the glue and hit with catalyst. She drove it about 5 more years - no problem.

BTW - it is not too cheap - but not bad.

Huh. A quick google seems to indicate the brand (Hobypoxy) is no longer being produced. Would agree that a fast set epoxy would be ideal here.

I may have misspelled it or it changed names - but I buy it all the time in various hobby shops.

Try "Insta-Cure" gap filling super glues. Found it

My new best friend is 3M's ScotchWeld using a twin-tube gun and mixing nozzles. Look at Grainger for a list of the large number of adhesives available. The dispenser is about $80, and the adhesives in tubes are $30, but they go a long way.

The adhesives go from slow to fast set, and can be matched to all kinds of materials.
