family businessExperience the legacy of NARES, the leading resin company in Portugal.

Founded in 2005, NARES is a Portuguese family business specialising in resins. Initially dedicated to providing industrial services, in 2020 it expanded its operations to include the commercialisation of metal drums.

In 2023, NARES, formerly Vieirifabril, was reborn under this name, with the aim of reviving what was once the largest resin derivatives factory in Portugal. Embracing tradition and innovation, and building a bridge between the past and the future.

As we begin a new chapter in 2024, NARES is expanding its portfolio by offering Portuguese rosin and turpentine under the renowned Costa & Irmãos brand. This is a significant step in our journey, increasing our offer with more complete solutions to meet our customers’ needs.

Vieirifabril was founded as a provider of industrial services.
