How to Stick Plastics

How to stick Plastics is such a challenging task to undertake that many people tend to just give up before they even get started. Before you can stick plastic to plastic, there are a few questions that have to be asked. For example, why are plastics so difficult to adhere? And why they are used so frequently as opposed to other materials such as wood, glass or fibre?

Plastics have a much longer life span than wood and are cheaper to produce. However, sticking this material is incredibly difficult for a variety of reasons. All Plastics are man-made with a completely different molecular makeup. These molecules are tightly packed together to create a ceramic like finish. The products available for bonding this material are limited in their performance, making bonding plastic to plastic that much more difficult.

Two component epoxies are traditionally used for bonding plastics where the hardener part of the epoxy etches into the material to create a strong bond. However, it still remains difficult to penetrate this tough molecular surface for a variety of reasons. For example, plastic is a very flexible material and needs a sealant that can withstand high levels of movement and vibrations. Even superglues containing cyanoacrylate will not be up for the job since it contains a high concentrate of solvent.

The perfect product for sticking Plastics is the unique CT1 construction adhesive and sealant. This is the product everybody is talking about not just for sticking Plastics but for sticking a multitude of different materials. Since it has been released, professionals in the market have named it The Snag List Eliminator.

So why is CT1 so good?

Well firstly, CT1 is composed from a unique formulation of a hybrid polymer with no petro chemicals in its makeup. This allows it to flow into the pours to create an immediate grab, perfect for adhering to even the most difficult materials to bond. The curing process starts almost instantly, resulting in a formidable bond which will remain flexible and accommodate high degrees of movement. A flexible sealant is a MUST when you want to stick plastic to plastic or plastic to any other material for that matter.

CT1 is used frequently by P.V.C. installers for fascia’s and box guttering, their comments are that “it’s the best thing since sliced bread” for bonding. Numerous sign makers are also using CT1 for bonding various signs. It is advisable before adhering this material to roughen the surface beforehand with either hard grain glass paper or a wire brush. This will provide the right kind of texture to adhere the material on a long-term basis. In addition to this, it is also advised to clean the surface with MultiSolve because despite the surface appearing clean to the naked eye, there can often be an oxide, (greasy) layer that remains invisible. Removing this will provide you with a clean surface, completely ready for bonding with CT1.
