HK-302 A / B for various components of the potting protection. Can be deep curing, two-component mixture has a good flow, the operating time can be adjusted according to the temperature of the curing agent to add the proportion. Before use without the use of other primer, the majority of the material has a good bonding effect, its characteristics:
◆ two-component high transparency liquid silicone rubber, condensation alcohol type
◆ low viscosity, easy processing, strong operation
◆ excellent high temperature electrical insulation, stability set
◆ excellent waterproof, moisture resistance
typical application
LED waterproof drive power potting, solar components junction box, LED display, LED lighting, wall washer, bar lights and fluorescent products such as potting.

Instructions for use
1. Mixing: before use, A, B glue before mixing evenly, and then by weight to remove the clean container to stir evenly;
2. Defoaming: natural defoaming (20-30min) or vacuum defoaming (-0.08--0.1MPa, 5-10min)
3. potting: in the operation time will be finished potting pottery, the responsibility will affect the leveling. The substrate should be kept clean and dry before potting.
4. Curing: can be cured at room temperature or high temperature curing. Curing speed is greatly influenced by curing temperature and humidity.
Precautions:
Storage and transportation
1.A, B components to be protected from light, heat, sealed
2. Store at 25 ° C for 6 months
