8 Tips for Using Polymer Adhesives

Polymer adhesives are high-strength glues, such as resins and epoxy glues. These adhesives are used for a variety of purposes including flooring, mosaics, engineering and packaging of materials. Polymer adhesives are available in a wide variety of forms and application strengths. You can choose from stick applicators, powders and liquid polymer adhesives, depending on your needs. Below are a few tips that will come handy when you use polymer adhesives.

1 – Choose the Correct Adhesive for Your Needs

Depending on the project you are working on, you must choose from many different varieties of polymer adhesives. If you have a large working area to cover and you need a high strength adhesive, a paste form of the adhesive may be best. Liquid polymer adhesives are more suited to small projects.

2 – Mix the Adhesive if Required

If you purchase a polymer adhesive in powered form, you will have to mix it according to the provided instructions. Keep in mind that polymer adhesives have different permissible ‘open times’, which means the interval of time for which they can be kept open as you apply the adhesive. Once you mix the adhesive, you must apply it before it dries out. Keep liquid adhesives tightly shut when not in use.

3 – Read Instructions Properly

It is important to read and understand all the mixing and usage instructions pertaining to polymer adhesives before you open the packaging. Any mistakes during the initial steps can lead to unusable adhesive or unsatisfactory results. After application, you may also have to hold the glued area together for some time to seal the bond. The instructions will give a clear idea on how to proceed.

4 – Take Necessary Safety Precautions

Always wear gloves when you open the packaging and mix the glue. Some polymer adhesives may emit toxic fumes. To be safe, wear a respiratory mask to prevent inhalation. If possible, leave windows open and work in a well-ventilated area.

5 – Keep Application Area Clean and Dry

Polymer adhesives work best on areas that are free of moisture, grease and dirt. Clean the application area well in advance.

6 – Maintain Required Temperatures in the Surroundings

Never expose polymer adhesives to cold temperatures as the polymers can break down and the glue may lose its adhesiveness. This can render the product useless for your needs.

7 – Prepare the Application Surface in Advance

If the application area is very smooth, the polymer adhesive may not adhere to its maximum potential. If possible, introduce some porosity and roughness to the surface. Scrubbing with sandpaper may be good for this purpose.

8 – Use Acetone or Isopropyl Alcohol to Remove Unwanted Adhesive

No matter how careful you are, sometimes accidents do happen and you may end up with unwanted glue on the sides or outside the boundaries. In this case, you can remove the glue when it is still wet with the application of a warm water-soap solution. If the adhesive has set, you will need to use acetone or isopropyl alcohol to remove the glue. Only use these substances on surfaces that will not be adversely affected by their application.
