What is VeroGray?
VeroGray (RGD850) is a rigid, opaque gray acrylic photopolymer for PolyJet material jetting, supplied in glossy and matte surface modes. It is a general-purpose choice for concept and appearance models where fine detail resolution and moderate strength are sufficient, with 57 MPa tensile strength, 17 % elongation and Shore D 84 hardness. The cured resin is a notch-sensitive thermoset, is neither weldable nor thermoformable, and yellows under UV, so it belongs in presentation and fit work rather than service parts. VeroBlackPlus covers the same duty in deep black. VeroGray has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 53°C (127 °F). VeroGray has a tensile strength of 57 MPa (8.27 ksi), stronger than 65% of polymer grades. Elongation at break is 17% and the elastic modulus is 2.5 GPa (0.363 Msi).
What is VeroGray used for?
- concept modeling
- form and fit prototypes
- presentation models
Limitations
- Limited service temperature — 45°C (113 °F), worse than 98% of polymer grades
- Absorbs moisture — dry before molding — 1.3%, worse than 88% of polymer grades
- Degrades in UV without stabilisers — 25/100, worse than 76% of polymer grades

Physical3
VeroGray has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 53°C (127 °F).
Mechanical9
VeroGray has a tensile strength of 57 MPa (8.27 ksi), stronger than 65% of polymer grades. Elongation at break is 17% and the elastic modulus is 2.5 GPa (0.363 Msi).
Thermal8
VeroGray is rated for continuous service to 45°C (113 °F). It conducts heat at 0.2 W/m·K (0.116 BTU/hr·ft·°F), worse than 56% of polymer grades. Thermal expansion is 80 µm/m·K (44.4 µin/in·°F).
Chemical & Environmental2
UV resistance is poor.
Sustainability3
Producing a kilogram of VeroGray takes about 120 MJ of energy and emits 6 kg of CO₂ — more than 73% of polymer grades. Typical recycled content is 0%.
Manufacturability2
VeroGray's machinability is good (55/100, worse than 64% of polymer grades).

Working with VeroGray
Is VeroGray easy to machine?
Drilling, tapping and light milling are possible with sharp tools and low feed, but the cured resin is notch-sensitive — avoid thin webs and coolant that contains ketones.
Can VeroGray be welded?
Thermoset, not weldable; join with cyanoacrylate or epoxy adhesives.
Can VeroGray be formed, bent or molded?
Not mouldable or thermoformable — geometry is fixed by the jetting process; keep walls ≥1 mm and avoid long unsupported spans.
VeroGray chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

| isobornyl acrylatereactive monomer | 15 – 30 | 22 |
| acrylic monomer (mixed) | 15 – 30 | 22 |

What surface finishes work on VeroGray?
Support gel removed by water-jet/NaOH bath, then sand from 400→1000 grit, prime and paint or vapour/clear-coat; UV-blocking clear coat is recommended to slow yellowing.

VeroGray — frequently asked
What is VeroGray used for?
VeroGray is typically used for concept modeling, form and fit prototypes and presentation models. In short: general-purpose PolyJet rigid; neutral grey for painting; concept-model workhorse.
What is the tensile strength of VeroGray?
VeroGray has a typical tensile strength of 57 MPa (8.27 ksi) — stronger than 65% of polymer grades.
Is VeroGray easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drilling, tapping and light milling are possible with sharp tools and low feed, but the cured resin is notch-sensitive — avoid thin webs and coolant that contains ketones.
Can VeroGray be welded?
Thermoset, not weldable; join with cyanoacrylate or epoxy adhesives.

Can VeroGray be formed, bent or molded?
Not mouldable or thermoformable — geometry is fixed by the jetting process; keep walls ≥1 mm and avoid long unsupported spans.
What is the maximum service temperature of VeroGray?
VeroGray is rated for continuous use to about 45°C (113 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
