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)

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.
