Blocking Pitches/ Waxes

Mainly consisting of natural and synthetic waxes these types of blocking pitches have a very low melting point. They are suitable for gluing at reduced tension and stress as well as for sealing the edges of optical parts when those are applied on multiple substrates.

Wax-based blocking pitches are particularly suitable for fastening bright-finished and mat plano-optic components to substrates. Its low melting point requires low processing temperatures, that, subsequently, has a positive effect concerning work at reduced tension. Due to its excellent adhesion and resistance to moisture, these protection compounds can be used without any oil-containing coolants and cleaning agents. Furthermore, these blocking pitches protect the plano-optic parts contacting the substrates.
