Product Description
Silicone Adhesive Sealant Flammable Resistant Electronic Potting Compound HM-315
potting compound for LED display
HM-315 potting adhesive
Brief introduction
HM-315 is two parts condensation silicone sealant, we can add the third part and make it mat. It’s cure at room temperature, release ethanol element while curing, no corrosion to PC,PP,ABS,PVC,copper,etc.With excellent adhesion to many electronical material(except PP,PE).
Properties
1.Low viscosity, good leveling, suitable to used as potting adhesive for complex electronical fitting.
2. After cure, it becomes soft silicone rubber, can resist strong impact.
3.Can resist high temperature and extreme weather condition, extend lifespan of electronical fittings.
4. Condensed type,no corrosion to electronical fittings while cure.
5. Do not require coat, has excellent adhesion to PC and Epoxy.
6. Anti-humidity, water-proof.Use this product as potting adhesive for LED screen, can reach water-proof IP68 level.
7. Excellent mat effect, especially suitable for occasion which requires mat effect.
Application
Potting adhesive for LED

Mix
Before applying, mixed A and B at ratio 10:1 (Volume or weight ratio)after two components are complete mixed, use vacuum pump to release the bubble, be careful the whole volume of adhesive should not more than one third of the container, in case overflow. We can also let the adhesive stay still for about 20-30 minutes to naturally release the bubble at 25C.
Potting and cure
Pour the mixed adhesive into the potting site as soon as possible in case of any air sneak into the adhesive. At room temperature, the adhesive could be cure into elastomer,low temperature could extend the cure time, by adjusting the mixed ratio can change the cure time.
Attention
1.This adhesive condense to cure with ratio 10:1 for part A and part B completely mixed. If require shorter or longer cure time which can be reach via adjusting ratio of both components.Normally,we don’t suggest heating, which can result in generating small bubble or pinhole, which have bad effect on appearance and sealing.
2.We suggest that potting thickness should not more than 50mm,normally thickness of 20mm,can release the bubble by staying still for a while. If require thick potting area, should at least put this mixed adhesive into vacuum container and at 700mmHg for at least 5 minutes.
3. Completely mix two components
4.If require mat effect,pls add the C component, and only after 24-48h of potting, the mat effect comes out.Relatively,higher temperature can accelerate the mat effect, but keep in mind, should be lower than 50C.
5. Color depends on customer’s requirement.
Test
We suggest that customers should test this product before application and see if it could meet the demand.
Shelf life
Store under 30C and stay sealed
Shelf life of component A and B is 12 months after the date of manufacture.
