FS-1702 black epoxy potting adhesive

Product introduction

FS-1702 is a two-component black flame retardant thermal conductivity epoxy potting adhesive with low viscosity, good fluidity and easy to enter the gap of the product. Can be cured at room temperature or temperature, curing speed is moderate; No bubbles after curing, smooth surface, luster, high hardness; The cured material has good acid and alkaline resistance, good moisture-proof, water-proof, oil-proof and dustproof performance, and resistance to humidity and heat and atmospheric aging; It has good electrical and physical characteristics of insulation, compression resistance and high bonding strength.

Product application

Widely used in circuit module, automotive electronic module, ignition coil, ignition module, power module, electronic components, PCB board and other potting protection and electronic product security.

Technical parameters before and after curing

Use technology

1, the product to be sealed needs to be kept dry and clean.

2, before mixing, first of all, the A component and B component in their respective containers fully stir.

3, accurately weigh according to the weight ratio, the ratio should be fully stirred after mixing to avoid curing.

4, generally speaking, the molding below 20mm can be natural defrosting after molding, because the high temperature causes curing speed or deep molding, so it can be defrosted according to needs. At this time, in order to remove the bubbles generated on the surface and inside of the molded, the mixture should be put into a vacuum container and defrosted at 0.8MPa for at least 5 minutes.

5. Pour the defoamed adhesive into the parts to be filled and sealed, and the products can be cured at room temperature or heated.

6, during the curing process, please keep the environment clean to avoid impurities or dust falling into the uncured adhesive surface.

Matters needing attention

1, the product will begin to gradually cure after mixing, its viscosity will gradually increase, and will release some heat.

2, the more the amount of glue mixed together, the faster the reaction, the faster the curing speed, and may be accompanied by the release of a lot of heat, please pay attention to control the amount of glue, because due to the reaction, its usable time will be shortened, the mixed glue as far as possible in a short time to use up.

3, all components should be sealed storage. The mixed rubber material should be used at one time to avoid waste.

4, this product is non-dangerous goods, but do not import and eye.

5, a small number of people contact glue for a long time will produce mild skin, mild itching, it is recommended to wear protective gloves when using, stick to the skin, please wipe with alcohol, and use detergent to clean.

Storage and transportation

1, Store in a cool and dry place, the storage period is 6 months (25℃).

2, this product is non-dangerous goods, can be transported according to general chemicals, careful in the transportation process leakage

Packing size: 25kg/ group (20kg for A component, 5kg for b component)

FS-1707 temperature resistant potting adhesive

This product is a two-component temperature curing high temperature potting material, can be used in high temperature environment for a long time, temperature resistance up to 200 degrees. The product is easy to use and fast curing speed.

Product parameters:

How to use:

1. Weigh A and B by a 1:1 volume ratio. The total mixture should not exceed 100g.

2. Mix well and pour into dispensing bottle.

3. Squeeze into the potting material through the dispensing bottle. The glue in the dispensing bottle is used up in 10 minutes.

4. The glue is initially cured within 1 hour (determined by the ambient temperature and the total amount of potting). Cure 24 hours, wipe away grease stains.

5. If the reaction speed is too fast, an appropriate amount of component C (slowing agent) can be added to extend the use time and slow down the curing speed. The recommended ratio is A:B:C= 2:2:1.

Curing conditions reference:

When the glue is at an ambient temperature of 20 degrees and the total mixing amount of AB is 10 grams, the curing time is 15 minutes. The initial solidification time in the gap is about 40-60 minutes. If the recommended ratio is followed, the use time and curing time can be about 30 minutes.

Packing, storage and precautions:
1, should be placed in a cool, dry place storage.

2. Components A, B and C of this product are separately sealed and stored for six months.
3. If the product is in contact with the skin, please wash it with soapy water.

4. This product is packed in 10kg/ set. Each set contains A component 4kg, B component 4kg, C component 2kg.

Note:

If the glue is placed for A long time, it will be stratified. If this phenomenon is found before use, it is necessary to stir A and B respectively and then mix them. Store the glue sealed after use. If the temperature rises and the operation time is not enough, C component can be added to slow down the curing speed. The specific amount needs to be adjusted according to the ambient temperature.

Package size: 10kg/ group (4kg for A component, 4kg for B component, 2kg for C component)
