3D-ADD AA2 Bio Hydrophobic Adhesive Additive for adhesion on difficult surfaces

Product description

3D-ADD AA2 is a bio-based hydrophobic adhesion-promoting additive designed for advanced photopolymer resin systems used in SLA, DLP and LCD 3D printing technologies.

The material is formulated to improve adhesion

 on challenging substrates such as metals, glass and engineering plastics, while maintaining a safer and more biocompatible-oriented formulation compared to standard adhesion additives.

This ultra-low viscosity additive enables efficient incorporation into resin systems without significantly affecting flow behavior or printing performance.

Application framework

Designed for incorporation into vat photopolymerization systems (SLA, DLP and LCD) in professional and industrial environments requiring enhanced adhesion combined with safer material profiles.

Typical applications

• Adhesion improvement on metal, glass and plastic build platforms
• Applications requiring safer or more biocompatible-oriented formulations
• General-purpose adhesion enhancement in photopolymer resins
• Stable printing on difficult or low-energy surfaces

Measured physical properties

• Form: clear liquid additive
• Viscosity: <10 cps (ultra low viscosity)
• Appearance: transparent liquid

Formulation guidelines

• Recommended loading: ~5 wt%
• Add directly to the base resin and mix thoroughly
• Compatible with most SLA, DLP and LCD resin systems

Functional performance characteristics
