About this product
ALTANA Cubic Ink Tough 2100 VP is a fast, easy-to-print functional resin with a strong balance of toughness, impact resistance and heat deflection — robust enough to drill, grind and finish into real functional parts.
Why engineers choose Tough 2100 VP
Impact resistance without the brittleness.
High impact, low brittleness
36 J/m notched and 380 J/m unnotched Izod, 12% elongation and >10% deflection at fracture. Parts absorb impact instead of cracking.
Stiff and strong
73 MPa tensile strength, 2800 MPa modulus and 118 MPa flexural strength hold load without excessive flex.
Machinable functional parts
Robust enough for post-treatment — drill, grind and finish without shattering.
Fast, colorful printing
Highly reactive with short exposure times. Available uncolored, black, cyan, magenta, yellow and clear.
Technical properties
Measured on uncolored resin (TDS v4). Post-cured 2×30 min UV, Formcure L @ 80 °C.

What is Tough 2100 VP best for?
It is a fast, easy-to-print functional resin for parts that must resist impact and handling — functional prototypes, jigs and fixtures, housings, snap-fits and end-use parts.
How tough is it?
It reaches 36 J/m notched and 380 J/m unnotched Izod impact, 12% elongation at break and over 10% deflection at fracture, so parts flex and absorb impact instead of shattering.
How does it compare to Loctite IND403?
Comparable stiffness and HDT with higher impact and elongation, at a lower price ($159.60 vs $230 per kg). Additive Plus stocks and supports both, so you can compare and choose with guidance.
What colors and printers are supported?
Available uncolored, black, cyan, magenta, yellow and clear, on LCD, DLP and mSLA systems (385/405 nm). Settings for Formlabs, Asiga, Prusa, Phrozen and Nexa are in the processing guide.
How is it processed?
Print, wash in Cubic Ink Cleaner 400 or IPA, then UV post-cure (2x30 min at 80 °C) to reach full toughness and HDT. An SDS ships with every order.
