PRODUCT DESCRIPTION

What is dichtol AM Hydro?

dichtol AM Hydro is a ready-to-use, water-based specialty sealer for additively manufactured components. Thanks to its safe properties, it is also suitable for use in more sensitive areas.

The product permanently seals 3D-printed components against liquids and gases while providing lasting protection for the surface against external influences. Compatible with all common printing processes and filaments –from FDM and SLS to PLA, ABS, and ASA.

YOUR BENEFITS

Why dichtol AM Hydro?

Permanent sealing – designed for the demanding applications of additively manufactured parts.

💧 Waterproof sealant

Reliably seals pores and microcracks in 3D-printed parts against liquids. Ideal for containers, housings, vases, adapters, tanks, and fluid-carrying components.

💨 Gas-tight seal

Creates a gas-tight surface that remains stable even under pressure. Suitable for pneumatic applications, pumps, and pressure testing.

✨ Protected surfaces

Seals and protects the surface from external factors such as dust, grease, and bacteria. More durable and stable, and provides a long-lasting seal.

🌿 Free of hazardous substances

Water-based formula free of hazardous solvents (VOC-free). Safe to use, environmentally friendly, and suitable even for beginners.

⚡ Ready to use

No mixing, no preparation—just open, apply, and you're done. Reusable. Colorless after curing. Saves time and money and prevents application errors.

🔧 Versatile

Compatible with all common printing methods (FDM, SLA, SLS, MJF) and most printing materials. A product suitable for a wide range of applications and projects.

STEP BY STEP

Here's how to use dichtol AM Hydro

Prepare the component
Ensure the surface is clean, dry, free of grease, and free of dust.

Select the application method:

Immersion: Fully submerge the part in dichtol for 5 minutes.
Brush application or spraying: Coat or spray the surface with dichtol and keep it continuously wet during the 5-minute treatment time.
Internal sealing: Fill in dichtol, gently swirl the part for 5 minutes, then pour off the dichtol.

Remove excess (optional)
After letting it sit for a short time, wipe off or allow any excess material to drip off the surface to prevent streaks or drips from forming.

Allow to cure
Allow the component to cure for 24 hours at room temperature. Do not test for leaks or proceed with further processing until after this time.

CASE STUDIES

What is dichtol AM Hydro used for?

From prototype development to mass production—dichtol AM Hydro solves the most common problems associated with 3D-printed parts.

Liquid Containers, Housings & Tanks

3D-printed containers, housings, vases, and water tanks are permanently sealed to be liquid-tight—even when in constant contact with water and oil.

Pneumatics & Pressure Components

Hoses, adapters, and housings for pneumatic systems are sealed to be gas-tight and reliably withstand operating pressure.

Aesthetic Enhancement & Protection

Surfaces that are regularly exposed to external elements are permanently sealed and protected. In addition, the surface is easy to clean after sealing.

Weather Protection & Outdoor Use

Protects printed parts used outdoors from moisture absorption and temperature fluctuations in outdoor applications.

Medicine & Laboratory Technology

Sealed components for use in process engineering, laboratory environments, and medical settings with heightened hygiene requirements.

Mass Production & Industry Sector

Ready to use and easily scalable. Can be applied by dipping or brushing. dichtol can also be applied with spray guns.

Sealing with dichtol is suitable for all common printing processes, such as FDM, SLS, SLA, and MJF. It can be used to seal plastics, metals, and ceramics as printing materials.

Regardless of the application method, we recommend applying the treatment continuously for 5 minutes.
Then let the part dry at room temperature for 24 hours – and you’re done.

We have demonstrated drinking water compliance for dichtol AM #2567, which means that no components leach out of the sealant when it comes into contact with drinking water. We currently do not have food contact compliance for any dichtol products, as this must always be tested for the entire component. Therefore, this must be determined separately by the customer for each specific application.

dichtol AM Hydro has a temperature resistance of 130°C. A detailed list of the temperature resistance of our dichtol products can be found in our download section.

Yes. You can easily pour the oil back into the bottle and reuse it. Please make sure the bottle is securely and completely closed.

No. dichtol is completely safe for flowers and plants. Because it penetrates deep into the pores and dries out, it does not leach into the water and remains permanently effective – no flaking or porosity.

Yes. dichtol offers excellent paintability and is colorless once fully cured.
