[Submit an inquiry for this product]
1. Synonyms:
2. 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.
3. Main Applications:
Relatively high resistance to heat, soft, relatively high
insulation, damp proof. Suitable for the wrapping of coil, soft mica bands,
soft mica boards, coating on jacket for fiberglass, heat resistant coating,
and protective sealant for transistors. Soft mica-sheet, soft mica-belt,
soft glass fabric, glass fabric tube, moisture-proof condenser, dipping and
paper treatment.

5. 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.
6. 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.
