Glue for Glass to Plastic – Buying Guide
Before we get into reviewing the best glue for bonding glass to plastic, let’s first go over some very important things that you should know.
Types of Glue for Glass to Plastic
There are a variety of glues that you may use to bond glass to plastic. Each one has its own special properties, strengths, and weaknesses too. So, let’s take a look at each to see what they have to offer.
Super Glue
This is one of the best types of glue to use for bonding glass to plastic. Super glue can be purchased in varying degrees of viscosity. Super glue tends to be one of the best options for balsa wood, as it forms a very tight bond that cannot be dissolved by adhesives once cured. They don’t have great impact strength, but they dry very quickly and work well with a variety of surfaces.
Hot Glue
Hot glue is ideal for a variety of surfaces, both porous and non-porous, which includes both glass and plastic. Hot glue sets very fast and forms a fairly strong bond. It’s also great at bonding uneven surfaces and for filling gaps.
PSA
Pressure sensitive adhesives are another option which you may choose to go with. These come in clear sheets and can be pressed onto virtually any surface. These work well for bonding various materials such as plastic, glass, wood, and more.
Spray Adhesives
Spray adhesives are very easy to use and can just be sprayed on. These are usually best for smaller and lightweight crafts. However, you can also purchase heavy duty spray on adhesive, which is designed for heavier tasks such as for gluing glass to plastic, and more.
Epoxy
Generally speaking, an epoxy style glue is going to be your best bet. These are designed for extremely tight and secure bonds, they can bond to virtually any material, and once bonded, are virtually impossible to split. These tend to come in two different parts.
Polyurethane
Another good option to go with is a polyurethane. These are multi-purpose glues designed for a very wide variety of applications. These form very strong bonds, but beware that they do take a few hours to cure and usually require clamping. Once cured, solvents cannot undo this type of glue.
How to Glue Plastic to Glass
Bonding plastic to glass with glue is not very difficult. Follow these few steps to get the job done with ease.
- Choose a type of glue that is made for bonding plastic to glass.
- Be sure that both surfaces, the glass and plastic, are perfectly clean and dry.
- Most superglues will dry very fast, so be sure to do some exact measurements before applying adhesive.
- Also, be sure to do this in a dry environment with a moderate temperature. You don’t want too much humidity or extreme temperatures involved.
- Be sure to apply adhesive sparingly. Most glues of this nature are the kind where a little goes a long way. Apply an even layer of the glue as needed.
- Apply pressure to the items being glue together to ensure that a tight bond is formed. You may have to apply pressure using a clamp depending on the type of glue you are using.
What to Look for when Buying Glass to Plastic adhesive
Before you go out and buy any kind of glue to attach plastic to glass, there are a few important purchasing factors which you should be aware of.
- Make sure the glue is in fact intended to bond glass to plastic. Not all glues can do this.
- Make sure to get a type of glue that forms a very strong bond, can deal with a lot of weight and pressure too
- Glue that has a high level of shock and impact resistance is recommended.
- Any glue you use should be totally waterproof. Having weatherproof glue is necessary if you plan on using it for outdoor applications.
- A precision applicator to make application easy is recommended. On that same note, you should go for glue that is relatively thick. Runny glue is messy glue.
- If you can find glue that is non=toxic and odor free, you are on the right track.
Gluing Plastic to Glass – Safety Tips
Now that you know what to look for, let’s quickly over a few important safety tips for gluing plastic to glass.
- Make sure to never ingest any glue, even if it is labelled as non-toxic.
- Wear gloves when using super glue. This stuff bonds skin together with ease.
- If using glue that has strong fumes, work in a well ventilated area and wear a face mask if necessary.
