Liquid sealing compounds from epple

Epple sealing compounds are liquid and silicone-free. They are available as pastes or liquids which either remain in their liquid state (permanently plastic sealants) or cure on application (film-forming sealants). Liquid sealing compounds have crucial advantages: they conform to every surface, so saving valuable time as extensive preparatory work is not required. In short: no laborious preparation of indentations, sections or grooves – and no extensive and expensive storage of solid sealing compounds.

The spectrum stretches from non-curing, permanently plastic sealants through curing sealants to very hardening, non-flexible systems. Special types are stable to aggressive chemicals like acids or alkaline solutions, and other sealing compounds withstand extreme heat – as much as 800°C. But there are further demands: high-maintenance components require easily soluble and non-adhesive sealants, easy to clean and usually removable. 


Liquid industrial sealing compounds for all purposes

As the needs of our customers are so individual and various, we have developed special sealing compounds for virtually all types of materials, streses ans connections.

The transition from liquid to solid materials is literally a fluid one. Exactly like adhesives, sealing components are used when the exchange (leakage) of gas or liquid between two spaces must be prevented. When sealing gaps, seams, surfaces and breaches, sealing components form a “bridge” between the surfaces of parts of the same or different materials. This works by the surface adhesion of the sealant to the part, or the stability within the sealing component (cohesion).

Typical questions relating to the correct choice of liquid sealing components:

  • What materials are to be sealed?
  • Are firm components or porous parts to be joined together?
  • What thermal stress will the connection be subjected to?
  • Is a stress with aggressive chemicals to be expected?
  • Will a connection later be subjected to high tension, strong shocks, vibrations, heavy or pressure loading?

... and the correct application:

  • Must a sealing component flow into a narrow gap or crevice?
  • What size gap must be bridged?
  • Is the base rough or uneven?
  • After what time must the mechanical resilience be achieved?
  • How high is the internal pressure?
  • What are the flow conditions?
  • Can a solvent-based product be used?
