Dichtol HTR HS 50S (High Temperature Resistant High Solid) is a highly capillary-active polymer mixture based on silicone resin. The low viscous system was designed to penetrate very deep into porous structures by capillary force and seal this gas and liquid tightness. The capillary deep impregnation or sealing with dichtol HTR HS 50S is resistant up to a maximum temperature of +500°C. Dichtol HTR HS 50S is a diluted 1-component system with a solids content of >50%. The high percentage of solids promises permanent and reliable corrosion protection. Diluted version of HTR HS #2530 with improved penetration for very fine pores.


  • Temperature resistance up to +500°C
  • Base silicone resin offers good electrical insulating properties
  • High solids content >50%
  • Fast curing at room temperature / No tempering or heating necessary!
  • Easy application, ready to use
  • Very good penetration behaviour (proven up to 80% in LDS layers)

Typical applications

  • Capillary deep impregnation of porous structures as well as micropores and hair cracks
  • Impregnation of leaking castings and metallic structures
  • Sealing of thermal coatings (LDS, APS, HVOF, etc.)
  • Sealing of porous graphite and ceramic components

Storage / Shelf life

Store in original, unopened container in a cool, dry place (+5°C to +20°C). Shelf life 1 year.

Processing / Preparation

The pores to be sealed must be clean and dry. It must be ensured that there are no dirt residues or foreign bodies (e.g. crack detection agents) in the pores, as these can have a negative effect on the penetration behaviour of the sealer. For cleaning dirty surfaces we recommend DIAMANT Cleaner #1417.


The product is a 1-component system. Please observe the application temperatures specified in the technical data. Application on too warm surfaces as well as application at too low temperatures can negatively influence the penetration behaviour of the sealer.

Brushing & Spraying

apply Dichtol HTR HS 50S in several operations, making sure that the surface to be sealed is covered with a film of liquid for at least 5 minutes.

Injecting & Pouring

For cooling channels or threaded holes, it has proven effective to pour Dichtol into the channel and leave it there for at least 2 minutes. Leave on for 5 minutes. If necessary, remove excess material after the exposure time.


Dip the component to be treated in Dichtol and after a reaction time of at least 2 minutes, apply Dichtol. Remove again after 5 minutes. Please make sure to drain the component properly. It is recommended to move the component during dripping to prevent deposits of Dichtol from forming in undercuts or cavities.


Dichtol HTR HS 50S dries under room conditions and cures in the presence of atmospheric humidity. Curing can be accelerated by temperature.
