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

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.

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

• 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

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
• Appearance: transparent liquid
• Viscosity: <10 cps (ultra low viscosity)
• Ultra low viscosity for easy mixing and homogeneous dispersion
• Form: clear liquid additive

• Promotes strong adhesion on metals, glass and plastics
• Improves wetting and surface interaction
• Reduces delamination and first-layer failure
• Maintains rigid, non-flexible material behavior
• Safer and bio-based formulation approach

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

• Compatible with SLA, DLP and LCD printing technologies
• Minimal impact on standard printing parameters
• Suitable for open material systems and custom formulations

• Organo-tin free formulation
• Bio-based and safer formulation approach
• Designed for reduced toxicity compared to conventional adhesion additives

Material performance depends on the base resin composition, printer type, exposure conditions and substrate characteristics. Adhesion and safety-related performance must be validated in the final formulation and application.

This product is supplied as a formulation additive for professional use in photopolymer engineering and additive manufacturing workflows. It is not a standalone printable material. Final performance and suitability must be validated by the user according to the intended application.

This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
