Silicone Resin

1. Properties:

Silicone resin are mixtures of solvent (toluene or xylene) with combined hydrolyzates of methyl chlorosilanes and phenyl chlorosilanes contain some amount of hydroxyl groups. The hydroxyl can further condensed into a hard film under heating. Solid content is 50~70% on sale.

Outstanding insulation property, high-and-low-temperature resistance, corona and electric arc resistance, water-proof.

Outstanding resistance to weather-aging, ozone and chemicals.

With silicone resin, the H-grade motor, other electric appliances would be size-small, weight-light, last-long and could be used under harsh environment.

When over loaded, the motor or other electric appliance would not go out of order and would not burn heavily. The gasses giving off are not poisonous. The remains after burning is silicon dioxide.

2. How to use:

Dilute with toluene, xylene or solvent-petrol;

Dip, spray or brush onto work-pieces;

Preheated at 110~140^oC first for extracting solvents, then heated at 160~180^oC, at last heated at 200^oC;

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 300^oC,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.

5. Packing, Storage and Transportation:

Packing: 25KG,100KG net in iron drum.

Storage: Keep away from sun, acid, alkali, fire and heat source. Keep in dry, cold and well ventilated place.

Transportation: As inflammable chemicals.
