DEWEIT both manufactures and supplies a variety of screen pastes:
— dielectric, protective
— conductive (resistive)
The conductive pastes’ compositions without the use of precious metals have been developed by us, which made it possible to make products available for use not only in industrial but also in domestic heating equipment.
The whole DEWEIT composite materials’ complex was created for thick-film technology being a set of dielectric pastes with firing temperatures T = 800 – 840 oC and conductive – based on metal borides (MexBy) with firing temperatures T = 770 – 800 oC, which are applied to both metal or ceramic basics.
DEWEIT screen printing dielectric and protective pastes are used in a protective dielectric layer based on aluminosilicate oxides (Al-SiхОy). The insulating layer resistance is not less than 50 MOhm, with a thickness of 150 μm, the breakdown voltage at this thickness is not less than 2000 V.
Low resistance screen printing pastes with the specific resistance of 0.01 – 0.03 Ohm / cm2, are used for single-level and multi-level patch boards on both ceramic and metal bases with a protective coating, ceramics’ metallization, including piezoceramics;
Resistive pastes, screen pastes, the specific resistance of which is 0.1 – 20 Ohm / cm2, are used for the resistive elements of hybrid integrated circuits’ manufacture;
Resistive pastes, screen pastes, the specific resistance of which is 0.05 – 50 Ohm / cm2, are used to make heating elements with a specific heat dissipation power of up to 50 W / cm2 and a supply voltage of 1.5 to 750 V.
DEWEIT screen pastes for screen printing are used to connect wire and ribbon leads to produce elements by sintering in electric furnaces, adhesion of at least 50 kg / cm2.

DEWEIT pastes combine a distinctive property – they have a slight diffusion of atoms in the functional environment of resistors at elevated temperatures. This property makes it possible to use these composites in difficult conditions of radiation pollution.
