Auto Plastic Adhesive
In terms of tensile strength, the strongest adhesives are epoxy adhesives, specifically single-component heat-curing epoxy adhesives. With a tensile strength of 35-41 N / mm² (5100- 6000 psi).
The tensile strength of the adhesive is simply how strong the adhesive is once cured. It says nothing about how well they bond to different substrates. In order of tensile strength, the highest values correspond to metal-to-metal bonding cases. The best performing adhesives are:
Single-component epoxies bond well to metals and offer a good alternative to welding, providing high shear, impact and peel strength. It provides excellent resistance to chemicals and temperature extremes. Shear strength in steel can reach 41 N / mm² (6000 psi). Note that steel surface treatment and joint spacing may affect ultimate strength.
Cyanoacrylate adhesives, especially pure methyl adhesives such as Permabond 910 and impact modified adhesives such as Permabond 731, have exceptional strength on steel 30 N / mm² (4400 psi). They do not have the same chemical and thermal resistance. Epoxy adhesives and acrylic adhesives provide better impact resistance than cyanoacrylates. The advantage is that cyanoacrylate may be easier to remove. Only warm water and soap will be needed to separate the surfaces. In some cases, temperature (100-120°C) can also be used with materials that can withstand it.

Best glue for plastic
There are other glues, such as wood glue or carpenter’s glue, that do not react as expected when applied to hard, high-density synthetic surfaces. This is the case for objects such as buckets, boxes and other containers. Hard plastics are made of polyethylene (indicated with a 2 or “HDPE”) or polypropylene (indicated with a 5 or “PP”) and if we have to work with them, it will be necessary to find an adhesive that guarantees the durability and effectiveness of the fixing.
Transparent plastic glue
INDEX OF CONTENTSIn today’s market, we can find all kinds of glues that have been designed for different types of materials to be joined. In this case, we have made a comparative list with the best glues for plastics, so that, when you go to the store to buy them or buy them online, you can buy the one that will really work and give you incredible results.
Pattex transparent plastic glueSee on AmazonThis product is one of those chosen by the leading experts in this type of glue, as it has the guarantee of an excellent brand like Pattex. Among its features we can highlight that it is transparent and therefore will not be seen when applied to the pieces to be joined, and it is water resistant, something that comes in handy if it is for example an object that is usually in contact with water or that can get wet by rain.
It is a transparent product that can be bonded in record time, so it is recommended to be precise in each application. A new formula has been developed to make it more resistant to water and to temperatures ranging from -50 to 120 degrees Celsius.
