At first glance it may seem that the choice of glue, the task is quite simple, especially for paper (cardboard). But, when you get feedback from both the children and their parents, whether everything turned out to be glued together, the situation turns out to be ambiguous.
The wrong choice of glue when you first meet with paper modeling, can forever discourage interest in this kind of creativity.
In order to choose the glue you need to understand:
1. What type of glue is right for us?
2. Choose a suitable glue manufacturer.
For example, glue-PVA from different manufacturers will vary greatly in price and, accordingly, in quality.
What kind of glue is suitable for gluing parts of polyhedra from the Magic Edges sets? What can you buy in the store for work?
First, we will clarify the characteristics of the material that will be glued. All parts of the Magic Edge sets are made of thick white paper (cardboard) with a thickness of 0.15 to 0.29 microns. For comparison, this is a much heavier paper, 3-4 times denser than regular office paper and even more dense than paper used in school notebooks. This characteristic immediately allows you to narrow the range of suitable types of glue. Therefore, we leave in our list only those types of glue that are suitable for gluing thick paper (cardboard). Of course, you can use more "powerful" adhesives up to epoxy, but the economic feasibility of this approach is questionable.
Secondly, among all the characteristics of glue for us the most important are two:
1. Gluing speed - pressed, held, released and everything stuck.
2. The strength of the connection after the glue dries - so that the model does not fall apart in the hands, if after a couple of days we take it from the shelf.
Glue stick (any manufacturers) - not suitable.
The reason - the glue is not designed to work with thick paper.
The strength of the connection of parts after drying is very low.
Office glue or liquid glue - not suitable (any manufacturers).
The reason - the glue is not designed to work with thick paper.
The strength of the connection of parts after drying is very low. In addition, the glue leaves a white mealy bloom, which eventually turns yellow.
