Product overview
DELO PHOTOBOND SJ4192 is a UV/visible-light curable, bio-based multi-purpose adhesive from DELO. The formulation contains 62% renewable raw materials (major resin precursors derived from corn and castor oil) and is designed for bonding metal, glass and a range of plastics, including polycarbonate.

Key features

• Bio-based content: 62% renewable raw materials
• High peel strength
• High flexibility across substrates
• Improved adhesion on plastics, notably polycarbonate
• Low outgassing
• Suitable for metal, glass and a variety of plastics

Application and curing
Typically dispensed by needle dispensing. Curing is achieved with UV or visible light within seconds, enabling fast processing and described as producing low CO2 emissions during curing.

Performance
Laboratory and application tests show that SJ4192 outperforms the non-bio-based predecessor in several mechanical properties, with notably improved plastic adhesion while maintaining high flexibility and peel strength across substrates.

Sustainability and development
With 62% renewable content, DELO PHOTOBOND SJ4192 is among DELO’s first products exceeding 50% bio-based raw materials. DELO continues development of additional bio-based systems, including light–moisture and light–heat curing variants.
