Functional Benefits
-
Superior Adhesion:
Designed for surfaces where standard acrylate adhesion fails — particularly metals and inorganic substrates.
Catalytic Activation for Vitrimers:
Provides latent catalytic activity in polymer networks, enabling dynamic bond exchange in vitrimers (thermal activation).
Enhances stress relaxation and reprocessability without sacrificing cured properties.
-
UV/DLP/SLA Compatible:
Efficiently incorporates into light-curable systems without significantly altering cure depth or exposure requirements at optimized loadings.
Suggested Usage
| Base 3D resin type | Recommended range |
|---|---|
| Standard 3D resins | 1–5 wt% |
| Filled composites (glass/metal) | 3–8 wt% |
| Advanced vitrimers / dynamic networks | 3–10 wt% |
| High-adhesion structural systems | 5–10 wt% |
Start at low loading and increase to balance adhesion and cure performance.
Performance Attributes
Adhesion
-
Improves wetting and chemical bonding to polar and inorganic substrates.
-
Reduces delamination and edge lift in prints.
Reactivity
-
Compatible with typical photoinitiators (radical or hybrid systems).
-
Acidic component may moderate cure speed — adjust photoinitiator accordingly.
-
Acts as a latent catalyst for dynamic exchange in vitrimer systems when activated thermally.
Mechanical Properties
-
Adds adhesion without dramatically increasing stiffness or brittleness.
-
Does not significantly alter baseline network crosslink density when used at recommended loadings.
Formulation Considerations
-
For vitrimers, pair with appropriate dissociative/linkable components to maximize exchange efficiency.
-
High acidic character may influence:
-
photoinitiator efficiency
-
filler surface interactions
-
surface tension
Adjust formulations accordingly.
-
Storage & Handling
-
Store in a cool, dry place away from direct light.
-
Typical shelf life: 6–12 months under recommended conditions.

Typical Formulation Example (Guide)
For a high-performance SLA resin targeting adhesion on metal and advanced interchangeability:
-
Base 3D resin: 82–88 wt%
-
3D-ADD AA3: 4–7 wt%
-
Optional fillers: 5–25 wt%
Adjust exposure and post-cure to balance surface activation and cured network dynamics.
It is supplied as a kit, which contains the product, one graduated beaker and one empty 250 mL black bottle to measure, mix, keep and protect the 3D resins from daylight. Please do not expose any 3D resins to natural or room light to prevent their curing.
