DIAMANT dichtol AM UV protection is a very low-viscosity, polymer-based impregnating agent for additively manufactured components. The product seals additively manufactured components gas- and liquid-tight and protects the component from UV radiation. This is made possible by a very thin protective layer of a few micrometers, which wraps around the particles and absorbs the harmful UV rays. dichtol AM UV protection seals and protects the component and can thus prevent discoloration of SLS printed polyamide (PA) components such as spectacle frames, for example.
Characteristics
Efficient material consumption
Wide range of applications through: dipping, brushing, injecting
UV resistance for 3D printed parts (independent of the printing process)
Temperature resistance up to +200°C
PMMA base with good recoatability
Fast curing at room temperature / no tempering or heating required
Very good penetration behavior / depth effect for sealing against gas and liquid
Typical applications
Capillary-active deep impregnation of micropores, hairline cracks and porosities
Selective serial impregnation
Individual impregnation (of large components)
Impregnation of rapid prototyping and additive manufacturing components
Sealing of porous graphite and ceramic components
Protection of surfaces against UV radiation
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
Remove dirt residues, foreign bodies, grease, liquids and other substances. Crack testing agents can negatively affect the
negatively. We recommend DIAMANT Cleaner #1417 for cleaning soiled surfaces.
Application
The product is a 1-component system. Please observe the application temperatures specified in the technical data
application temperatures and the information in the safety data sheet. Application on surfaces that are too warm can also
too low temperatures can have a negative effect on the penetration behavior of the product.
Inject & Fill
Apply dichtol crosswise in 4 working steps at intervals of approx. 1 minute. Keep the surface moist for at least 5 minutes
to ensure sufficient time for deep penetration.
Dipping
Immerse the component to be treated in dichtol and remove after a reaction time of at least 5 minutes. Please ensure that the component drips off properly. It is recommended to move the component while dripping to prevent deposits of dichtol from forming in undercuts or cavities.
Curing
dichtol AM UV Protection dries out physically in a few hours (approx. 1 hour per mm of wall thickness). Due to the rapid drying of Dichtol, it is possible to use the components again after a short time. See table “Technical data”.
Notes for 3D printing
We have found that 3D printed components are sometimes very different in terms of microstructure and pore formation.
We can therefore only provide limited application instructions for immersion times or exposure times. In the many tests
that we have carried out ourselves have shown a tendency for the extension of the immersion or exposure time to produce positive results.
Immersion times of up to 60 minutes were tested and in some cases showed considerably better results than shorter immersion times. Repeated application also showed significant improvements in some cases. We therefore recommend for 3D printed components (especially metals and polyamide), we therefore recommend longer soaking and immersion times where possible and, if necessary, repeating the impregnation process.
Repeat the impregnation process if the components are not yet sufficiently sealed.
