Our mission, as a company specializing in surface treatment is to offer innovative technical solutions with a quality beyond our customer`s expectations. We offer consultancy before and after the sale, in order to develop partnerships with our customers, whilst always maintaining our target, the health and safety of our employees and respect for the environment.

Research & Development

Smaltiriva always invested a lot of resources in R&D, hiring qualified personnel and investing in sophisticated instrumentation to detect chemical-physical properties of raw materials and coatings (DSC, contact angle, infrared spettroscopy, thermogravimtry, sal spray fog cell, AFM...).

Specially in the last years, a lot of investments in new laboratories have been made in order to deeper investigate coatings and understand mechanisms which influence surface properties (at nanometric level) in terms of antistick, dry lubrication, permeation/corrosion resistance.

The development of new coatings is handled in cooperation with PST Corporate R&D, qualified Univertities and selected suppliers of raw materials.

From this activity, Smaltiriva has been able to boost product/process innovation which gives the possibility to offer to its customers more performant and fine-tuned solutions.

R&D department, furthermore, gives a constant and valuable support to quality department in the definitions of technical specifications, monitoring of environmental and food contact regulations


From the starting of its activity, when it was a family owned company, Smaltiriva considered health and safety of its employees as the core value, investing a lot of money in upgrade of equipments and individual protective devices.

When Smaltiriva merged into Praxair, this attention to safety became even higher, introducing continuous training for all employees, internal and external audits, review of every ( even small) incident in order to work as much as possible on preventive actions.

Praxair phylosophy is that every incident is preventable , safety is a “line responsibility” from the top management to the worker level : the health and safety of its workers is the main value of the company and for this reason investments in safety are major items of expenditure.

In 2013 Praxair obtained safety certification according to OHSAS 18000, an international standard for safety management which can be obtained only if safety “culture” in the company is at the highest levels.

Same attention Praxair has for compliance to environmental regulations and for this reason since many years Praxair invested in cathalythic abatement systems to reduce emissions of solvents and particulate far below existing limits.


SMALTIRIVA began its activity in 1969 as a forerunner in Europe to offer coating services for industrial application: NON STICK, EASY –TO-CLEAN, DRY LUBRICATING, ANTI-CORROSION, WITH HARD MATRIX.

In 1998 SMALTIRIVA became part of PRAXAIR SURFACE TECHNOLOGIES, fully owned by Praxair Inc. USA., and today is a division of Praxair Surface Technologies, a company specialised in surface treatments: ceramic, hard coating.

SMALTIRIVA today employs over 90 people in 2 different plants in Italy: Monte Marenzo (LC) and Mantova.

Smaltiriva processes all types of Teflon® coatings, such as PTFE, PFA, FEP and EFTE, for applications from small parts in large volumes to larger parts for one-off projects such as cylinders and vessels. In addition to large tunnel ovens for full robotic mass production, Smaltiriva can handle parts up to 10 meters in length, and weights up to 20 tons.

Anti-corrosive coatings as well as non-stick hard matrix coatings including plasma technology are also applied: in particular the unique and exclusive Plasma Coatings®, a special non-stick and wear-resistant coating.

Smaltiriva is also the leader in the research and application of the world famous SBSTM Bakeware Technologies: a range of non-stick coatings for oil-free baking.

The mission of our company is to offer in the field of surface coatings innovative technical solutions, quality above expectations and a counseling service before and after sales can develop a partnership with our customers, which ranks as the first target health and safety of workers and the environment.

As for safety, since he was a family business, Smaltiriva has always placed the health and safety of employees as its first objective by investing a lot of resources for adaptation of machinery and individual safety devices.

With the acquisition by Praxair, this attention is further enhanced through continuous training of all personnel, internal and external audits, analysis of every incident in order to be able to take preventive measures at the highest levels.

In 2013, Praxair has also obtained the OHSAS 18000 which is an international standard for the management of security that they can get only those companies that have reached a high "maturity" in the safety culture.

Already in the early '90s Smaltiriva obtained the certification of its quality system according to UNI - EN-ISO 9003 and then get to the beginning of the 2000s the UNI-EN ISO 9001 which covers all business activities and in 2008 the certification according update of the UNI-EN-ISO 9001: 2008.

As for innovation, Smaltiriva has always invested heavily in research and development, devoting highly qualified and acquiring cutting-edge equipment for the determination of the chemical-physical and structural properties of the raw materials and coatings (DSC, corner contact, infrared spectroscopy, salt spray, AFM).

In recent years there have been significant investments in laboratories Smaltiriva in order to analyze in detail the coatings, understanding the mechanisms that determine the surface characteristics (nanometer level) non-stick, dry lubrication, resistance to permeation and corrosion.

The development of new coatings collaborates with the Corporate R & D PST Indianapolis, the primary colleges / partnership with the most qualified suppliers of raw materials.

Mantova & Monte Marenzo, Italy


From early 80’s, Smaltiriva started investing in quality not only in terms of product/process, but also in terms of training to employees and interpersonal relations, as well as attention to customers and suppliers ( total quality approach ).

Early 90’s Smltiriva obtained quality certification according to UNI-EN-ISO 9003, and later on early 2000 obtained certification UNI-EN –ISO 9001 ; in 2008 obtained certification in accordance to the new ISO rules UNI-EN-ISO 9001: 2008.

Smaltiriva quality depatment operates in close cooperation with PST Corporate quality department which monthy monitors quality KPI and periodically audits quality system and requires detailed actions plans for performance improvements.

Quality department has very sophisticate instrumentation to monitor processes and product quality and they are available also for customers to check and fine tune process parameters and obtaining the best performance of the coatings ; thanks to a close cooperation with internal R&D department , it is possible to make very detailed “failure analysis “ reports.

Quality Accreditations

Food Compliance

All coatings offered by Smaltiriva for the food industry are guaranteed to the continuous contact with the food during its production phase, thus also for the temperatures that the various production processes may require (in some cases, even over 200 ° C).

The guarantee is produced, in accordance with local regulations, by means of the continuous cooperation with a specialized institute, able also to perform the required tests, the chemical-physical character, which may be from time to time required for obtaining conformity to food contact.

The reference standard for a polymer coating remains the European Regulation N ° 1935/2004, as well as all the directives that refer to it.

These Regulations must then be integrated with the laws, rules and regulations, where they exist, which, while not constituting a waiver or an alternative to the European regulation, represent an integration of the observance of which is equally compelling.

Recently, the introduction of the new regulatory body in the European Regulation No 10/2011, applies to all plastic products, has further specified the requirements that a product must undergo plastic to be compliant for food contact. Although this regulation does not apply, according to the intention of the European legislator, coatings, plastic nature, it nevertheless constitutes a useful integration, in favor of the safety of the user and the consumer, with respect to the Regulation 1935/2011. This is the reason why coatings Smaltiriva are voluntarily tested also according to the dictates of this new regulation.
