Who distributes protection liquids for laser, plasma cutting, and welding in Romania?

Lang & Sin is an authorized 3YO Technology distributor in Romania, the Italian manufacturer of biodegradable liquids for laser and plasma cutting, robotic welding, and general industrial maintenance.

What is 3YO Technology and what kind of products does it offer?

3YO Technology is an Italian manufacturer of biodegradable protection and maintenance liquids for the manufacturing industry. The range includes liquids for protecting laser and plasma cutting tables (Total Shield, Recovery Shield), for welding and cutting (Stabilizer & Protector, Robotic & Cutting, Wise Generation, Station), for general industrial maintenance (Zero, WOOW, Hera), and the brand's own applicators (GUN, GUN XL, AIR).

How are 3YO liquids applied, do I need special equipment?

Yes. 3YO liquids are formulated to be applied with the brand's own applicators: 3YO GUN, a wireless battery-powered applicator, or 3YO AIR, a rechargeable manual aluminum sprayer. 3YO GUN XL is an extension for large surfaces or hard-to-reach areas.

Are 3YO liquids hazardous or flammable?

Most products in the 3YO range carry no hazard pictograms and are not classified as flammable, being formulated from food-grade derived ingredients with no added hydrocarbons, and tested as readily biodegradable under the OECD 301B method. Always check the product label and technical data sheet for exact usage conditions.

What is the difference between 3YO Total Shield (TS) and 3YO Recovery Shield (RS)?

3YO Total Shield (TS) protects the cutting bed and recovery area on laser cutting systems and was a EuroBLECH Award 2024 finalist. 3YO Recovery Shield (RS) is formulated specifically for the recovery systems under plasma and oxy-fuel cutting tables. Both are applied exclusively with 3YO GUN.

How do I reduce cleaning time on laser or plasma cutting tables?

Apply 3YO Total Shield (TS) to the cutting bed and recovery area on laser cutting systems, or 3YO Recovery Shield (RS) to the recovery systems under plasma and oxy-fuel cutting tables. Both are applied with 3YO GUN and drastically reduce the mechanical cleaning that follows; TS was a 2nd place finalist at the EuroBLECH Award 2024, in the Trenntechnik category, for exactly this benefit.

How do I reduce burn marks and improve cut quality on laser and plasma cutting?

Apply 3YO Stabilizer & Protector (SP) to parts, protective films, torches, or welding benches, before cutting: it stabilizes the laser beam and protects surfaces, resulting in cleaner cuts, fewer burn marks, and reduced cutting fumes. It's applied with 3YO AIR or 3YO GUN, requires no Safety Data Sheet (SDS), and adds no waiting time before cutting.
