After the first post on Adhesives, we promised you that we would follow up on the topic of adhesive-backed fasteners, given the vastness of the subject. A promise is a promise and here, for you, is the fascinating world of artificial rubber adhesives, also known as HOT MELT adhesives.
As we’ve said many times, there’s no one adhesive for all surfaces. Hot melt adhesives, however, do their best so that they are always on top of the situation, or should we say, of the surfaces! They go well on a great many materials, BUT, there’s always a BUT:
The fastener with acrylic adhesive is resistant to UV rays and can be used outside. The temperature range is usually between -30° and 160°C.
Instead the fastener with hot melt adhesive is often not very suitable for use outside. It has a much reduced temperature range, and is ideal for use inside.
Why are they called in this way:
The words themselves tell us: “hot” and “melt”. In short they are applied on fasteners by heating them.
On which surfaces can they be applied:
In general, these adhesives have an excellent adhesive force on almost any material, in particular on metals, polyester, polycarbonate, ceramic and many plastic materials, even with low surface energy such as polypropylene or polyethylene. A fire retardant version also exists (important in the transport sector).
Why is it good and useful to know that they exist?
Because all our fasteners, whether Duotec® , Klettostar® or any other Binder product, can be supplied with this adhesive, which is suitable for solving a great many problems.
And finally: what do they look like?
Our products with hot melt adhesive are distinguished by a white liner:
