Product Description
Sealing-grade self-healing booster for barrier and encapsulation applications in SLA/DLP/LCD resins (385–405 nm). It upgrades flexible bases to ultra-low-permeation, chemical-resistant materials that can re-close superficial cuts under mild heat and pressure. Three tuned versions: Optic (clearer look, low odor), Thermal-Weld (strongest reseal under heat), and BioGen (biogenic positioning with mild-heat activation).
Versions
Optic — Sealing performance with the clearest appearance and low odor at recommended loadings.
Thermal-Weld — Emphasizes hot-weld reseal strength for demanding barrier interfaces.
BioGen — Biogenic self-repair pathway supporting renewable-content narratives with mild-heat activation.
Key Features & Benefits
Self-sealing behavior for superficial cuts and micro-leak paths
Ultra-low gas/liquid permeation and chemical resistance
Improved interlayer cohesion for printed seals and encapsulations
Strong damping and vibration isolation; low bleed-out
Industrial durability; optical-friendly variants available (Optic/BioGen)
Typical Applications
Custom gaskets and O-rings, sealing lips and flanges, chemical-resistant bellows and boots, encapsulation and barrier geometries, fluid management components, leakage-mitigation interfaces.
Recommended Use Level
Additive mode: 20–30 wt% into a flexible base to add self-sealing and barrier performance
Matrix mode: ~50 wt% for dedicated gasket/encapsulation prints where maximum barrier and reseal are prioritized
Processing & Activation
Blend under low light until uniform before printing
Print on 385–405 nm systems; opaque/darker tones may require slightly longer layer exposures
Activation guide (validate on internal coupons): Optic ~50–80 °C with mild pressure; Thermal-Weld ~50–80 °C targeting firmer reseal; BioGen ~50–80 °C with mild pressure. Cool in contact to lock the interface. Follow the host resin’s standard post-cure.
Typical Properties (as supplied)
Appearance: amber to dark amber, high-viscosity liquid
Odor: technical, low volatility
Viscosity (25 °C): ~2000–5000 mPa·s
Density (25 °C): ~1.40–1.55 g·cm⁻³
VOC: extremely low
Compatibility
Designed for flexible, barrier-oriented photopolymers operating at 385–405 nm; suitable for clear and pigmented systems. In highly filled or opaque matrices, verify exposure settings and activation windows on internal coupons.
Safety & Handling
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 the SDS for this additive and for the host resin.
Storage & Shelf Life
Store tightly closed at 5–25 °C, dry, protected from light. Shelf life: 12 months unopened.
What’s Included (kit)
Additive, one graduated beaker, and one empty 250 mL black bottle to measure, mix, and protect the resin from daylight. Keep resins away from natural or room light to prevent unintended curing.
