3D-ADD HDT1 Bio, biocompatible Heat Deflection Temperature booster for custom increase of HDT

Product description

3D-ADD HDT1 Bio is a biocompatible Heat Deflection Temperature booster for custom rigidity refinement of 3Dresyns.

It is designed for custom boosting the HDT of 3Dresyns and is normally used at 5-10% dosage or more depending on HDT specifications for certain thickness.

Application framework

Designed for use with 3Dresyns systems to increase Heat Deflection Temperature and refine rigidity in compatible photopolymer formulations.

• Water absorption: < 0.01 % (24 h at 23°C) (ISO 62)

Functional performance characteristics

• Ultra effective booster of HDT
• Ultra fast curing
• Ultra rigid at room and at high temperature
• Excellent chemical resistance
• Durable

Processing and handling performance

• It is supplied as a kit, which contains the product, one graduated beaker and one empty 250 mL black bottle to measure, mix, keep and protect the 3D resins from daylight
• Please do not expose any 3D resins to natural or room light to prevent their curing.
• 3D-ADD HDT1 Bio is normally used up to 5-10% dosage (or more depending on HDT specifications for certain thickness)

Chemical and safety characteristics

• Biocompatible
• Organo-tin free

Testing & processing disclaimer

High Heat Deflection Temperature HDT 3D resins despite being rigid tend to be fragile and have a short lifetime, degrading thermally at high temperature.
