Huntsman introduces water-clear SL resin
Huntsman has introduced the RenShape® SL 7870, which is a true water-clear stereolithography resin that produces ultra-durable
models and prototype parts that are ‘as clear as glass’, according to the CIELAB colour scale system.
“In addition to outstanding polycarbonate-like clarity, colourless RenShape® SL 7870 delivers prototype parts with excellent impact resistance,
higher than that of other clear SL resins currently available.”
This latest addition to Huntsman’s range of next-generation hybrid SL photopolymers, RenShape® SL 7870 can be used in producing long-lasting
parts that feature a high-quality, smooth surface finish and precise replication of complex detail. It is also suitable for building investment casting
patterns.
Parts made from RenShape® SL 7870 maintain long-term dimensional stability even after exposure to warm, humid conditions (40ºC and 90%
R/H) and elongation of 22%. It is formulated to conform to FDA USP 23 Class VI standards for use in medical modeling and prototyping. Like
RenShape® SL 7800 and RenShape® SL 7810 next-generation photopolymers, RenShape® SL 7870 resin is a low viscosity, stable liquid that is
suitable for use on solid state laser and SLA® systems.
