LEO metal polymers (cold welding systems)
Areas of application
Photos of repair works
LEO metal polymers are made according to TU 2257-002-48460567-00, their properties and processing characteristics are confirmed by Quality Certificates, RF Hygiene Certificates as well as Maritime Register.
LEO metal polymers appear as the broad-functional compositions. High adhesion properties combined with structural strength, corrosion and wear resistance allow you to apply LEO metal polymers as adhesives in machine parts recovery, and as anti-corrosion and erosion coatings during replacement of surfacing welding.
Initially, LEO metal polymers represent a two-component paste which cures when mixed, forming a rigid three-dimensional structure. In a pasty state, LEO metal polymers are easily applied on any surface with a spatula. After curing, LEO metal polymers may be mechanically processed, along with metals.
Compared with traditional repair technologies, the "cold surfacing welding" method using metal polymers has the following advantages:
- the ability to recover parts made of any materials (ferrous and non-ferrous metals, non-metals);
- adhesion of dissimilar materials, including metals with non-metals;
- high chemical resistance to acids, alkalis, oils, solvents and other aggressive environments;
- no temperature and assembly stress after repairs;
- the ability to restore defects without disassembling and removal of units and mechanisms.
Internationally, the industrial production of special polymeric repair materials (including metal polymers) has got a long history. The most famous companies producing such materials are Belzona (USA), MultiMetall (Germany), Diamant (Germany), Unirep (Germany), Loctite (USA).
