„Can I have that in a writing form please?“
When the telephone rings in our application technology laboratory, the caller isn't always asking about the best way to bond materials. Sometimes the caller simply says: "Could you please send us a verification that your glue is vegan?" – or halal or kosher or something else. Things which only put a hint of a smile on someone's face can make an important competitive difference for a packaging manufacturer.
Polyamide hot melt adhesives on the basis of renewable raw materials
Polyamide hot melt adhesives on the basis of renewable raw materials
Resource-caring handling and sustainability of products used are possible even when using melt adhesives. Manufactured from renewable raw materials such as Diemer fatty acids from castor oil and rapeseed oil, polyamides (PA) show the characteristics of excellent melt adhesives even when unformulated. PA melt adhesives are mostly used in sectors with high requirements: for example when assembling technical components, electronics assembly, automobile construction and shoe production.Many polyamides have an extremely high heat resistance (up to 180°C) depending on their viscosity, and all this at excellent low-temperature resistance. Specially developed types pass the tests carried out in the automobile sector at temperatures of between -35 and +135°C.
Surface pre-treatment
Surface pre-treatment
In terms of adhesion technology there are requirements on the surfaces to be bonded to ensure successful bonding. This is because even the "greatest and best" adhesive can only carry out its task if it can set up sufficient adhesion. To do this, the service may need to be specially pre-treated which would include two important steps:- Preparation

Energy savings through better insulation connected with bead increased safety
Energy savings through better insulation connected with bead increased safety
We have been supplying all our Type HB 20 applicator heads for bead application with additional insulation since 2015. Applicator heads are used for automatic processes. If you want to reduce piece costs at large item quantities, if precision during manual application using a manual gun is not sufficient, if space availability does not allow manual application, or if the adhesive application has to be monitored, applicator heads of various types can be used.
The main body of an applicator head is made of metal, which has good thermal conductivity. However, without insulation the applicator head also gives off heat into the environment. This means that heating up the applicator head at the beginning of work takes longer, and more energy is required to retain the set temperature during work.
