What is the difference between Hot Melt and Low Melt?

It seems obvious, we know, but it’s a common question people are asking via Internet search engines. And it’s a question we ask our customers when they purchase a glue gun from our range. There are two options:

Hot Melt – for use with all Tecbond Glues, except Low Melt Glues

Low Melt – for use with Tecbond LM44

These guns are often referred to as High Temp and Low Temp glue guns. They have fixed settings – 195°C for high temp guns and 130°C for low. In some cases (for example the Tec 820-12 and Tec 820-15), glue guns have adjustable temperatures, from low to high melt.

Low Melt glue guns

Low melt glue guns are safe and easy to use. They carry a reduced risk of burns due to a lower temperature and are commonly used for bonding heat sensitive materials, arts and crafts and schools. We’ve even seen a customer apply a low melt adhesive (Tecbond LM44/12) directly to an inflated balloon without the balloon popping! They come with restricted glue formulations.

Hot Melt glue guns

High melt glue guns have a wider selection of adhesive formulations to choose from. These cover the bonding of more challenging materials like polypropylene, plastics, ABS, acrylics and even metals.

All of our glue guns are available in both hot melt and low melt versions.

Choosing between Hot Melt and Low Melt glue guns

You should always choose your Tec glue gun according to the kind of glue being used, the dispensing rate you need and the nature of your project. High temperature glue guns cover the majority of Tecbond glue stick formulations, which offer a wider range of options for bonding. Low Melt glue sticks operate at a lower temperature and are therefore safer to use, as risk of burns are reduced. However, Low Melt glue sticks only come in a selected range and are usually used for bonding heat sensitive materials like polystyrene.
You should never use Tecbond Low Melt glue sticks in a hot melt glue gun (or hot melt glue sticks in a low melt glue gun) unless specifically directed by a member of the GlueGunsDirect team.
