How do I avoid stress cracks when bonding plastics?

Stress cracks occur when the short-term mechanical strength of a plastic is subjected to adverse forces. Reducing or preventing stress cracks is accomplished with a careful design of compatible substrates and consistent manufacturing and assembly processes.

There are several areas to consider when looking for the cause of stress cracks in plastic components.

1. Manufacturing/Extruding/Molding processes
2. Thermal co-efficient compatibility of substrates
3. Adhesive chemistry & application process
4. Assembly processes

First – Examine plastic components for existing stress and where possible, eliminate causes due to machining, molding, extruding, etc.

Second – Review the substrates for differences in thermal co-efficients. A wide difference indicates a need for flexible and resilient adhesives that will move with the substrates as they undergo temperature changes.

Third – Select an adhesive recommended for the type(s) of plastic to be bonded and test thoroughly before beginning full scale production.

To further minimize or reduce stress cracks while bonding plastic substrates with adhesives:

1. Avoid solvents and solvent based adhesives.
2. If using cyanoacrylate apply the absolute minimum amount of adhesive to bond area and remove any squeeze-out from surrounding area.
3. Optimize relative humidity (40% – 60%) when using cyanoacrylates to accelerate cure time.
4. Use of an accelerator may be required to speed the cure time of cyanoacrylates.
5. Minimize or reduce the time the uncured adhesive remains on the plastic for “cure-on-demand” adhesives, such as UV and light-curable, or bead-on-bead two component formulas. The faster you cure the adhesive, the less likely stress cracking will occur

Last – Review the component assembly process and compare to design specifications.
Tapered fittings are subjected to hoop stress, for example, and over-insertion will exacerbate existing cracks in the substrate. Adhesives and solvents lubricate tapered fittings making it easy to over insert one part into the other. To avoid adding stress, control the distance that the tapered piece is inserted into the cylinder and use solvent free adhesives.

In summary, careful selection and application of adhesives to plastics can produce component assemblies that meet design specifications. Consult the manufacturer for assistance in selecting the optimum combination of plastic and adhesive to meet the application requirements.

What type of glue for ABS plastic like legos?

I want to cut and modify some lego pieces for customization purposes. Want type of glue is strong and colorless for this task?

You can use Testors "plastic cement" (available in any good model-hobby shop), but better yet would be "Pro-Weld" from Ambroid...

It is specifically formulated for ABS, Acrylic, and Styrene plastics. It's about $4 for a 2 fluid oz bottle, and I've been using it for YEARS on my model railroad and other plastic construction. It can be found in "better" model-hobby shops.
