How do different types of surfaces affect the adhesion of glue and tape? (Science Fair)

Abstract

This science fair project was conducted to compare the adhesive strength of different types of adhesive tapes on a smooth surface. The tests were done with the use of a steel plate and cellophane tape, duct tape, scotch tape, electrical tape and masking tape.

Hypothesis

The duct tape is the stickiest, and will require the greatest amount of force to pull it off the steel surface.

Background

Adhesive tapes

There are many types of adhesive tapes available for us to choose from. They are available in many sizes and colors. Adhesive tapes can also be transparent, colored, single side, double sided or in the form of adhesive foam strips. Depending on the application for which they are intended, these tapes are made of different types of materials and adhesives. Some of the common types of tapes are cellophane tape, duct tape, scotch tape, electrical tape and masking tape.

Duct tape is one of the most versatile tapes and they can be used for many applications like holding carpets in place, repairing hoses, binding books and even holding together parts of a broken window. They are normally used in places where long-lasting, flexible and strong adhesive is required.

Electrical tape is normally used in homes or automobiles to insulate electrical wiring. In homes, they are normally used for installing electrical fixtures such as lights and fans. Their purpose is to insulate wire joints and terminate exposed live wires to prevent short circuits or electrocution in case someone accidentally touches the exposed wire.

The most common type of tape found in all homes is the transparent scotch tape and the cellophane tape. These are multipurpose tapes and they are used to gift-wrap presents, stick paper together and to seal plastic bags.
