Description
dichtol HTR macro concentrate is a specially developed, heat-resistant polymer-based impregnation system. With dichtol HTR smallest pores, up to 0.1mm, can be sealed. this enables a very high pressure tightness on components, even with difficult object structures. for locally known leaks, selective impregnation ensures efficient use of material
Characteristics
- Efficient material consumption due to selective application even with vagrant porosities
- Varied application possibilities through: dipping, brushing, injecting, spraying
- Temporary corrosion and transport protection
- Drinking water and food authorisation
Typical applications
- Impregnation of metals, impregnation of castings
- Sealing of thermally sprayed coatings (sealers for APS, HVOF, LDS, flame spraying)
- Infiltration of 3D printed components, additive manufacturing, generative manufacturing
Storage / Shelf life
Store in original, unopened container in a dry, cool and frost-free place (+5°C to +30°C). Shelf life 5 years.
Processing / Preparation
Dirt residues, foreign bodies, grease and other substances must be completely removed from the pores to be sealed. For this purpose we recommend the use of DIAMANT Cleaner #1417.
Application
The object or application temperature should not exceed +40°C, otherwise the penetration behaviour of the polymer may be reduced.
Brush & Spray
apply dichtol in 4 stages at intervals of about 1 minute and keep damp on the surface for at least 5 minutes.
Inject & Fill
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.
Dipping
Dip the component to be treated completely in dichtol. After a reaction time of at least 5 minutes, remove the component and allow to drain well.
Curing
dichtol WFT cures within a short time. Please refer to the table for the exact times. We distinguish the hardening in three stages:
Surface hardening = time from which the material is grip-resistant and can be moved
Mechanical through-hardening = time from which the material can be mechanically processed
Full through-hardening = time from which the material has reached its full chemical resistance
