Dichtol HTR HS (High Temperature Resistant High Solid) is a highly capillary-active polymer mixture based on silicone resin. 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 capillary deep impregnation or sealing with dichtol HTR HS is resistant up to a maximum temperature of +500°C. Dichtol HTR HS 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.

Storage / Shelf life
Store in original, unopened container in a dry, cool and frost-free place (+5°C to +30°C). Shelf life 1 year.
Processing / Preparation
Dirt residues, foreign bodies, grease and other substances must be completely removed from the pores to be sealed. Crack testing agents 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.
Brush & Spray
apply sealant crosswise in 4 working steps at intervals of about 1 minute. Keep damp on the surface for at least 5 minutes to ensure sufficient time for deep penetration.
Inject & Pour
dichtol into the space to be sealed (e.g. blind hole, threaded hole, cooling channel, etc.) and allow to react for at least 5 minutes. Then, if necessary, pour off excess material.
Dip the component to be treated in dichtol and after a reaction time of at least 2 minutes, apply dichtol again. 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 cures under room conditions and hardens in the presence of humidity. Curing can be accelerated by temperature.
