Non yellowing, antidegradation and stability additives

Choose your non-yellowing or stabilizer route

Use the routes below to navigate the collection by the type of stability or protection logic you want to introduce.

• Reduced yellowing and improved optical stability.
• Anti-aging protection and better long-term appearance depending on system.
• Improved resistance to degradation mechanisms.
• Stability enhancement for clear and colored parts.

Typical use scenarios across the collection

This collection is suitable for material systems where long-term visual appearance and degradation resistance are important selection criteria.

• Clear or appearance-critical parts: where yellowing or optical drift must be minimized.
• Long-term prototypes: where retained appearance matters over time.
• Light-exposed components: where UV-related aging is a concern.
• Optical and display applications: where clearer and more stable appearance is relevant.
• Stability-focused formulation development and validation: where additive tuning is part of the workflow.

How to choose the right non-yellowing or stabilizer additive

Select the most suitable route according to whether the project needs yellowing control, UV protection or in-can stability support.

• Need a bio-based and biocompatible non-yellowing route → choose 3D-ADD NY1 Bio
• Need clear UV protection → choose 3D-ADD UVP1
• Need black UV protection → choose 3D-ADD UVP2
• Need in-can stabilization → choose 3D-ADD STAB1 or 3D-ADD STAB2 Bio

• Prioritise optical clarity and reduced yellowing → start with NY1 Bio or UVP1
• Prioritise dark UV-shielding route → start with UVP2
• Prioritise storage and resin stability in the bottle/can → start with STAB1 or STAB2 Bio
• Prioritise bio-based and biocompatible positioning → compare NY1 Bio and STAB2 Bio

Decision tree summary

Use this simplified engineering logic before detailed formulation validation.

• Need non-yellowing → NY1 Bio
• Need clear UV protection → UVP1
• Need black UV protection → UVP2
• Need in-can stabilization → STAB1 / STAB2 Bio

Then validate the final route under the intended resin family, additive loading, exposure conditions and storage workflow.

Bio-based and biocompatible non-yellowing additive

For projects that require reduced yellowing and improved long-term appearance in clear or appearance-critical printed parts.

Clear and black UV-protection additives

For formulations that require added UV-protection logic to support long-term appearance or degradation resistance.

Stabilizer additives for resin storage stability

For workflows requiring in-can stabilization of 3D resins, including a bio-based and biocompatible route.

A stability-focused platform rather than a single appearance modifier

This collection is structured around three complementary stability logics: reduced yellowing, UV protection and in-can stabilization.

• NY1 Bio covers the non-yellowing route.
• UVP1 and UVP2 cover clear and black UV-protection routes.
• STAB1 and STAB2 Bio cover in-can stabilization routes.

The right route depends on where the stability problem appears

These additives are most useful when the stability objective is clearly defined first: reduced yellowing in the final part, UV-related protection during service life, or resin stabilization during storage before printing.

In practice, the correct path is to define the failure mode first, then validate the additive under the intended resin chemistry, loading and exposure or storage conditions.
