【 Properties and Uses】
|
it is a polyester modified polyorganosiloxane resin solution, with excellent resistance to high temperature, electric insulativity and moistureproof performance, resistance to chemical corrosion, low solidifying temperature, good drying performance and low foam when dipping, used to produce heat-resistance covering paint and used in dipping H-grade dynamo, electric appliances and transformer coil.

【 How to use】
|
Dilute with toluene, xylene or solvent-petrol;
Dip, spray or brush onto work-pieces;
Preheated at 110~140oC first for extracting solvents, then heated at 160~180oC, at last heated at 200oC;
Catalyst can be added to accelerate the process, mall amount of catalyst such as naphthalene acid will improve the process a lot. Zinc-,lead-, manganese-, cobalt-carboxylate and amine could be used also;
The amount of added catalyst is decided by experience. To avoid gelating, the resin added catalyst must be used up as soon as possible.
The silicone resin containing some amount of aluminum powder can be used at temperature as high as 300oC,even higher.
Cautions:
-
Diluent must not contain water, sulfur-containing organic stuff, pyridine and other impurities. Otherwise the adhesion would be lower, the coating film would be viscid.
-
As large amount of solvent (as toluene, etc.) will give off in the processing, workshop must be well ventilated, keep away from fire. Also, labor protection is essential.
-
Impurities, dirty powders, etc., could damage the insulating property, so the shops, equipment and tools must keep clean in the processing.
-
Acid, alkali, carboxylate and amine quickening the cure process, lowing down the resistance to the high-temperature and damaging the insulation properties, the resins must be isolated from the above stuffs.
