LA TECNOGALVANO has over fifty years’ experience in the sectors for traditional galvanisation and surface treatment of metals and plating on plastic, offering integrated solutions for galvanic processes, systems and services for analysis, research, design and technical consultancy.
A wide range of products, in particular innovative galvanic processes with environmentally-friendly formulas, can be used in numerous fields from technical applications (valves, sanitary fitting, HVAC, devices for the food and automotive sector) to the decorative sector, plus the electronics and printed circuit industry through our subsidiary, Index 2 S.r.l.
The first revolutionary response to galvanic treatments and finishes.
Trademark, property of La Tecnogalvano. An environmentally-friendly alloy coating.
T.E.A.+® process is a valid alternative to classic nickel, nickel+chrome and electroless nickel plating for the food industry (drinking water and food) and for industrial sanitary fitting, taps and valves.
It is highly corrosion resistant in strong acidic or alkaline environments: thicknesses of 2-4 µm withstand NSS, ASS 96h and CASS 48h salt spray tests.
It fulfils the limits imposed by international standards for drinking water:
It allows semi-bright coatings to be obtained, which are extremely passive, with excellent guarantees of resistance to wear and free from micro-cracks.
|PROCESS||Tea Plus||Ni-Cr||Basic material (Brass)|
|Ni in H20 release||LOW||HIGHT||LOW|
|Pb in H20 release||LOW||HIGHT||HIGHT|
Ideal for application in the following sectors:
t is applied directly on copper, copper alloys and nickel, white bronze (T.E.A.®B), silver.
It is also used on mechanically satin-finished surfaces or with satin nickel bases.
EXCELLENT RESULTS: semi-bright coatings which maintain the colour intact, resulting in the desired decorative effects.
T.E.A.+ ® can be applied in rack and roto barrel galvanisation.
The processing stage and the parameter values vary depending on the type of application.
First stage: ultrasonic chemical degreasing - electrolytic degreasing.
Second stage: neutralisation.
Third stage: application of T.E.A.+®.
Fourth stage: final drying of article.
OPERATIVE PARAMETER RANGE::
Temperature: 50 – 60 °C
Voltage: 0.3 – 1.5 V
Current density: 0.1 – 4 A/dm2
Coating time: 20-50 minutes
In addition to supplying the process, LA TECNOGALVANO also performs T.E.A.+®.
A highly technological galvanic pilot system started up in January 2019. With fifty years’ experience in supplying galvanic treatment processes, services and consultancy, La Tecnogalvano is able to perform plating processes based on different requirements, guaranteeing quality results.
