3D-ADD Self-Heal Elastomer — Optic · Thermal-Weld · BioGen

Product description

Self-healing booster engineered for hydrophobic, oil/fuel-resistant elastomeric photopolymers for SLA, DLP and LCD printing at 385–405 nm.

It enables heat-assisted re-closure of nicks and scratches, strengthens interlayer fusion, and preserves damping behavior and chemical resistance. Three tuned versions are described: Optic, Thermal-Weld and BioGen.

Application framework

Designed for use with hydrophobic elastomeric photopolymers operating at 385–405 nm in SLA, DLP and LCD systems. Suitable for clear and pigmented systems requiring self-healing, improved interlayer fusion, damping behavior and chemical resistance.

Typical applications

• Custom gaskets and sealing lips
• Vibration and impact dampers
• Protective boots and bellows
• On-demand maintenance parts for automotive and industrial environments

Measured physical properties

• Appearance: light yellow to amber, viscous liquid
• Odor: low
• Viscosity (25 °C): ~800–1500 mPa·s
• Density (25 °C): ~0.95–1.05 g·cm⁻³
• VOC: negligible
• Recommended use level: 10–25 wt% in elastomeric resins
• Optic activation: ~60–90 °C with light pressure
• Thermal-Weld activation: ~60–90 °C under light pressure
• BioGen activation: ~60–90 °C with light pressure
• Storage: 5–25 °C, dry, protected from light
• Shelf life: 12 months unopened

Functional performance characteristics

• Moderate-heat re-closure of nicks and cuts
• High resistance to oils, fuels, greases, hydraulic fluids
• Improved interlayer fusion and fatigue tolerance
• Low bleed-out
• Sustained damping and energy absorption
• Optical-friendly behavior for Optic and BioGen
• Firmest weld response for Thermal-Weld
• Optic version: clarity-first, low-odor self-repair with minimal print re-tuning
• Thermal-Weld version: stronger heat-assisted welds for maintenance-grade parts exposed to shock and cyclic loads
• BioGen version: hydrophobic biogenic self-repair pathway that supports renewable-content narratives

Processing and handling performance

• Blend under low light to full homogeneity before printing
• Print on 385–405 nm systems
• Re-optimize initial and per-layer exposure slightly vs. baseline
• Opacity and viscosity can require minor increases
• Cool in contact to lock the interface
• Follow the host resin’s post-cure
• Designed for hydrophobic elastomeric photopolymers operating at 385–405 nm
• Suitable for clear and pigmented systems
• For highly filled or opaque matrices, validate exposure and activation windows on internal coupons
• Industrial/R&D use only
• Use standard PPE (gloves, goggles, lab coat) and adequate ventilation
• Avoid prolonged exposure to intense light during mixing and handling
• Consult SDS for this additive and for the host resin
• Additive, one graduated beaker, and one empty 250 mL black bottle to measure, mix, and protect resin from daylight are included in the kit
• Keep resins away from natural or room light to prevent unintended curing

Chemical and safety characteristics

• VOC: negligible

Testing & processing disclaimer

Activation guide and exposure settings must be validated on internal coupons. For highly filled or opaque matrices, validate exposure and activation windows on internal coupons.
