 Double Component Silicone Adhesive  KL-301(A/B)

This products is a heat curing double component silicone adhesive,It can be glued well with all kinds of materials after curing. The raw materials are characterized good flowing ability before curing and the better electrical insulating property after curing. Applied to silicone bonding with silicone to have insulation proof,moisture proof, shock absorption and sealing function.

Physical Properties：

Before curing：

Mix viscosity(25℃)，mΡa.s:             50000

Specific Gravity(g/cm³):                 1.10

Operable time(25℃),h:                  4.0

Curing time（80℃）,min.:              30-60

After curing:

Tensile strength(Mpa):                  4.0

Hardness(Shores A):                   35±5

Elongation(%):                         300

Adhesive property:             ≥2.0(A1-A1,cohesive failure )

Volume resistance(Ω • cm):             1×10

Dielectric strength(KV/mm):              20

Method of application:

•  Application ratio: A:B=1:1(weight ratio)

•  The adhesive is added by weight ratio and thoroughly mixed.

•  Before gluing,the thoroughly mixed adhesive should be degased vacuum degassing,

•  Brush the mixture glue onto the surface under the vacuum condition.

•  Curing at 170°C for 10-15 minutes.

•  Mixed with primer coating(CL-24S-3) will make the metal which glued with cured  silicone more viscosity

Note：

•  Kept in a seal place.

•  Curing time and  the size of sealant parts accordance with heat transfer efficiency under the certain temperature.

•  Testing compatibility of rubber and base material before using. Becuase the compound which contained sulfur, tin,arsenic,phosphorus,nitrogen,PB will cause of bad curing during the curing process.
