“Glue plastic? What You Need To Know About Gluing Plastics.”
There are more searches on how to glue plastic than on any other repair issue. Plastics, even poly-plastics are now easy to glue/repair. Watch our videos and you will see how easy it is to glue plastic, quickly easily and permanently.
A summary of the techniques for gluing/repairing plastics (the “Bonding Poly ProcessTM” (patent pending) appears below. One of the problems with plastics is that there are three types of plastics, poly-plastics, resin (toy, modeling) plastics and acrylics (plexiglass).
To bond/repair poly-plastics, a primer must be used. If you are unsure what type of plastics you’re dealing with, prime your plastic. Priming will not hurt the plastic if your piece is not a poly.
Once a poly-plastic (or other poly) has been primed, all plastics are treated the same and you will get a superb repair with any plastic. The “Bonding Poly ProcessTM” appears below.
For plastics, acrylic plastics (plexiglass), poly-plastics, co-polymers and polymers use the following steps, starting with step 3.. If the material is a polymer, co-polymer, or a polyolefin use the Poly-Bonding Poly Process TM (BPP) (patent pending) described below.
Poly-Bonding Poly Process TM (BPP) (patent pending)
The Poly-Bonding Process™ for poly-plastics and other polymers begins at step 1. The process for acrylics and resin plastics begins with step 3.
- Begin by saturating both edges or surfaces* of the poly item to be repaired/bonded with the Poly Prep.
- Let the Poly Prep dry.
- Spray one edge/surface of the polymer or plastic with our solvent based A/A.
- Warm both edges with a heat gun or hair dryer for 20 to 30 seconds (110 to 115 degrees Fahrenheit. Warm not hot.)
- Apply the SI adhesive to the opposite edge from where you sprayed the Activator/Accelerator.
- Press the two edges together.
- Warm the seam with a heat gun or hair dryer for 15 – 20 seconds.
- Done, though full cure with plastics takes up to seven days.
When the repair is a crack, the procedure is slightly different. Again polymer repair begins at step 1, other plastics at step 3.
- Spray the Poly Prep.
- Let the Poly Prep dry.
- Take a blow dryer or a heat gun and WARM both edges/surfaces for thirty seconds.
- Apply a structural adhesive (Usually SI Blue) to the crack.
- Align the two edges/surfaces and press for fifteen to twenty seconds.
- Spray the seam with the Activator/Accelerator.
- Take the hair dryer or heat gun and warm the seam for thirty seconds.
* If you don’t have heat available, you will still get an excellent glue join by just using the Poly Prep, a solvent based AA and an SI adhesive. If you don’t have either heat or the AA, the Poly Prep and SI adhesive will also work.
A link to the kits that will bond poly-plastics appears below.
To glue plastic that is a resin plastic (toys, models) or an acrylic plastic (plexiglass) use the following link. You need the Activator/Accelerator and heat to achieve the best results.
