Basically, there are four types of adhesives, depending on their manufacture: pure acrylate adhesives, modified acrylate adhesives, natural rubber adhesives and emulsion adhesives.

herpa print GmbH normally uses acrylate adhesives because of their higher-quality characteristics, but natural rubber adhesives and emulsion adhesives also suffice for less demanding applications. 
 
 
 
 

Advantages of acrylate adhesives

  • Suitable for adhesion onto paint, metal or plastic surfaces or for oiled backgrounds
  • Temperature-resistance of -40 to +150 degrees Celsius
  • High chemical resistance
  • High initial adhesion
  • Suitable for use outdoors
 
Acrylate adhesives are available, just like natural rubber and emulsion adhesives, with very different properties for different applications. These adhesives can therefore be distinguished from each other according to the following characteristics:
