Dichtol HTR HS AS (High Temperature Resistant High Solid Anti Stick) is a highly capillary-active polymer mixture based on silicone resin with non-stick properties. The low viscous system was developed to penetrate very deep into porous structures by capillary force and to shoot this gas and liquid tightness. The material is adjusted to have a very low surface energy and thus minimizes the adhesion of dirt and impurities. The capillary deep impregnation or sealing with dichtol HTR HS AS is resistant up to a maximum temperature of +500°C. Dichtol HTR HS AS is a concentrated 1 component system with a solids content of >98% and is therefore considered a solvent-free system according to VdL-RL04. The high percentage of solids promises permanent and reliable corrosion protection.


  • Temperature resistance up to +500°C
  • Base silicone resin offers good electrical insulating properties
  • Low surface energy = good non-stick properties
  • High solids content >98%
  • Fast curing at room temperature / No tempering or heating necessary!
  • solvent-free system according to VdL-RL 04
  • 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 dry, cool and frost-free 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 AS in several working steps and make sure that the surface to be sealed is covered with a liquid film for at least 5 minutes.

Injecting & Pouring

In the case of cooling ducts or threaded holes, it has proved effective to pour Dichtol HTR HS AS into the duct 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 HTR HS AS and after a reaction time of at least 2 minutes, apply Dichtol HTR HS AS. 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 from forming in undercuts or cavities.


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