3Dresyn CR UHT Chemical Resistant Ultra Hard Resin (Acids & mild Alkalis)

3Dresyn CR UHT is an ultra hard and tough chemically resistant photopolymer designed for SLA, DLP & LCD 3D printing.

This synthetic thermoset crosslinked network material is engineered for excellent chemical resistance to polar and non polar chemicals, including most strong chemicals such as strong alkalis, acids, oxidizing and reducing agents. It provides higher chemical resistance but more brittle behavior than 3Dresyn CR UT.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional and industrial environments requiring excellent chemical resistance, high rigidity, high temperature resistance and dimensional stability.

Chemical resistance, dimensional stability, thermal resistance and final mechanical performance depend on part design, printing parameters, post-curing conditions, exposure time, chemical environment and full workflow implementation. Final suitability must be validated by the user for the intended application.

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.

For chemical-resistant engineering applications, compare related resin routes when toughness, temperature exposure or chemical environment requirements differ.
