Description
Rubber Paint Protections for Industrial Masking
Barbieri Rubber rubber paint protections are catalog parts specifically designed for masking on industrial painting lines. They cover threads, holes, studs, threaded pins, through-holes and blind holes during paint cycles, preventing paint deposit on technical surfaces to be preserved. Designed to withstand oven cycles and to be reused multiple times, reducing consumable cost and masking time.

What rubber paint protections are for
Paint protections shield technical parts from paint: threads, assembly seats, reference holes, mating surfaces, electrical contacts, studs and locking nuts. Silicone rubber resists oven cycles and keeps enough elasticity for fast removal at end of process. The range includes round caps, cone caps, square caps, hood-style protections, cap protections for nuts, studs and threaded pins.
Available compounds
Standard compound for paint protections is VMQ silicone, chosen for high-temperature resistance and reuse over multiple cycles. Typical hardness is 50-70 Shore A.
| Compound | Temperature range | Feature | Typical applications |
| EPDM | -40 / +100 °C | Water, steam, ozone resistance | Painting, outdoor |
| NBR (Nitrile) | -40 / +130 °C | Mineral oil resistance | Workshops, hydraulics |
| VMQ (Silicone) | -60 / +200 °C | High-T resistance, reusable | Oven painting, high-T |
| FKM (Viton®) | -10 / +180 °C | Aggressive oils, solvents | Chemical, automotive |
| NR / SBR | -50 / +90 °C | Good mechanical elasticity | General caps, masking |
Catalog standard version and custom designs
The standard range of paint protections includes a wide series of caps and protections, with active tooling at Barbieri Rubber and no tooling cost for the customer. For special protections (dedicated caps for custom geometries, marked protections, special compounds, dedicated colors) we produce custom items: at least a preliminary drawing from the customer is required. The dedicated mold is manufactured in cooperation with our trusted toolmaking partners.
Industrial applications
Paint protections are used on industrial painting lines for automotive, vehicle service equipment, metal fabrication, technical furniture, frames and metal structures, appliances, fixtures and plants. They are also requested by manufacturers of agricultural machinery, pump units, compressors and any company with internal paint cycles. They reduce masking time and paint waste.
Frequently asked questions
Are paint protections reusable?
Yes. In VMQ silicone, protections can be reused over multiple oven cycles. Lifespan depends on oven temperature and history of previous cycles.
Which compound should I choose?
VMQ silicone is the technical choice for high-temperature oven cycles and for maximum protection life. We assess oven conditions case by case for precise advice.
Are they available from stock?
Yes, an extensive range of paint protections is standard catalog with no tooling cost for the customer. For protections with custom geometries the custom-design version applies.
Can I order colored protections?
Yes. Paint protections are often supplied in bright colors (red, orange, yellow) to ease visual detection and full removal at end of cycle. Coloring is agreed at order stage.
Can I request protections with special geometries?
Yes. For dedicated caps on pins, nuts or custom components we produce protections with a dedicated mold, manufactured in cooperation with our trusted toolmaking partners. At least a preliminary drawing from the customer is required.
