AUTHORISED APPLICATORS FOR DACROMET & GEOMET IN ROHTAK, HARYANA

Advantages & Properties

NO HYDROGEN EMBRITTLEMENT

The non-electrolytic coating process does not cause any hydrogen embrittlement because: Mechanical surface preparation (degreasing + abrasive cleaning) prevents any risk of hydrogen embrittlement during the entire process. When chemical surface cleaning is used, the curing at 300 deg C and the non-crystalline structure of the coating ensure the absence of embrittlement.


OVERALL COVERAGE

During the dipping process, all the internal surfaces of parts are protected e.g. spring pins, Nuts small assemblies, clips etc.


NO POLLUTION

The DACROMET & GEOMET is almost pollution free process.


WEATHERABILITY

Under normal atmospheric conditions, the DACROMET & GEOMET Coating provides very long life which is proportioned to the thickness of the coating itself.


CORROSION RESISTANCE

At equivalent coating weights, DACROMET & GEOMET has a corrosion resistance superior to many other systems. This resistance is due to the barrier effect created by the overall coverage of zinc and aluminum flakes and to the sacrificial protection of zinc controlled by the film


Grade A : Min. 24. g/m2 = (approx 5µ)
Grade B : Min. 36. g/m2 = (approx 8µ)
N.B. up to 25 µ can be applied if required.


RESISTANCE TO 5% NEUTRAL SALT SPARY TEST

(ASTM B117, BS 7479, DIN 50021)
DACROMET & GEOMET performance considerably exceed the requirements specified by the automobile industry :
Grade A :
Min. 250 hrs without white rust,
Min. 500 hrs without red rust,
Grade B :
Min. 250 hrs without white rust,
Min. 1000 hrs without red rust,
These performances remain unchanged after a heat treatment of 8 hours at 260ºC.


RESISTANCE TO CYCLIC TESTS

DACROMET & GEOMET conforms to the different cyclic tests used by the automobile, industry ( 3C Renault, P-VW 1210 VW / Audi, APGE, CCT1, CCT2, etc.


RESISTANCE TO KESTERNICH TEST (DIN 50018 – SFW 2.0 S)

This test is an acidic attack of the coating. Therefore, the resistance is directly proportional to the coating weight. Depending on the parts, a coating thickness to 8 to 10µ provides a resistance superior of 3 cycles or more.


RESISTANCE TO BIMETALLIC CORROSION

Excellent performances in contact with aluminum, chromium, zinc and tin; but less corrosion resistance with stainless steel, copper, nickel and lead.


HEAT RESISTANCE

Properties of DACROMET & GEOMET PARTS are maintained up to about 280ºC DACROMET & GEOMET IS THEREFORE perfectly suitable for parts in the engine compartments of vehicles.


RESISTANCE TO ORGANIC PRODUCTS

Excellent resistance to solvents, fuel and hydraulic fluids. DACROMET & GEOMET is an electrically conductive coating. The DACROMET & GEOMET film can be covered by a part form which has duriet metal adhesion (e.g. DACROKOTE)
