Silicone Adhesive For cellphone screen covers KL-2620A/B/C/D

KL-2620A/B/C/D is four components compound. Heat and fast cured type of silicone adhesive,no primer needed.Good flowing capability before cured ,The cured silicone adhesive has a good adhesion to stick with PET base material and improving the surface Stripping Resistance. After cured,has good adhesion strength, excellent exhaust,high transparency, no adhesive residue, high temperature resistance, high humidity, can directly replace the same level products of Dow Corning and KCC products.


The silicone adhesives are characterized by good leveling property, electrical insulating property, and high grade of transparency and easy to clean with water. Mainly applied to the computer display screen, mobile phone screen protector, PET touch screen film series.Can be coated to PET film by lamination machine.




No foggies on PET film

No fog, No white dots, super clean

High grade transparency, Light transmission rate 94%, Screen effect is vivid

The eyes don't feel sleepy when long tem exposure to PET screens  


Customised peeling (force) adhesion

                                                                             Adjustable peeling strength at 0~ 1200g , spare from primering base 

                                                                             Precise concoction of peeling adhesion

                                                                             Low peeling adhesion easy peel, high absorbing properties


Zero silicone transfer

No adhesive residue, Zero silicone transfer in full weather

No adhesive remains 




Appearance And Component:

2620A:Transparent colloid containing platinum catalyst. 

2620B:Transparent silica gel

2620C:Tackifier(Increase the adhesion between PET film and silicone adhesive)

2620D: Pressure sensitive adhesive (increase D component ratio can increase the silicone surface stripping force)


Viscosity: <50000mpa.s

Solid Content: 60% 

Curing Condition: TC10:19S*150u2103


Stored Condition: Room temperature

Light transmission:  94%

Refractive index (sodium yellow light wavelength 5893 10 ^ - 10 meters)  : 1.48

(For example, coated 10 microns stripping force 3g/25 mm)

1. Solid content 24%, mixing uniformity with solvent by a ratio of A:B:C:D:Solvent =100:100:10:40:560

Solid content 35%, mixing uniformity with solvent by a ratio of A:B:C:D:Solvent= 100:100:10:40:300

2. Taking material according to proportion, first mix B material and C and solvent evenly, and then mixed with A material evenly for about 20 minutes.

3. Defoaming treatment with vacuum by requirements. Coating uniformity of silicone adhesive on the silicone or PET film surface by coating method.

4. Testing at laboratory baking for 2~3 minutes at 150u2103.



For producing Baking temperature depend on coating thickness. Ranging from 90u2103 to 160u2103. For 10 takes about 50~60 seconds.
