KL-2610B is heated and fast cured type of silicone adhesive,combine with platinum catalysts PT4000, tackifier KL - 6600, KL - 298 used together,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 ofDow 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 displayscreen, mobile phone screen protector, PET touch screen film series.Can be coated to PET film by lamination machine.
Appearance And Component:
PT4000: platinum catalysts
KL-298:Tackifier(Increase the adhesion between PET film and silicone adhesive)
KL-6600:pressure sensitive adhesive ( increase the silicone surfacestripping force)
(for example, coated 10μmstripping force 2g/25 mm)
1.(1)Micro concave roll coating method
Advise to use solid content is 24% of the formula ratio (weight ratio) PT4000:2610B:KL-298:KL-6600:Solvent =1:200:10:40:340
(2)Comma blade coating method
Advise to use solid content is 35% of the formula ratio (weight ratio) PT4000:2610B:KL-298:KL-6600:Solvent =1:200:10:40:160
2.Taking material according to proportion, first KL - 298 and solvent mixed evenly, and then add in turnKL-6600→KL-2610B→PT4000 , to achieve uniform mixture stirring 20 minutes
3. Coating uniformity of silicone adhesive on thePET film surface by coating method or rolling process.
4. Testing at laboratory coating method 10 μmbaking for 1 minutes at 130℃.
Production coating method for reference
Set the oven temperature as from 90 ℃ to 160 ℃ to 140 ℃, The baking time and temperature is adjusted according to the coating quantity,the adhesive thickness of the coating when 10μm, glue baking time control between 50 to 60 seconds ,the adhesive thickness of the coating when 20 microns,glue baking time should be controlled in 100 ~ 120 seconds is advisable.Please change according to the specific equipment and operation method.
Storage:Stored at room temperature for 6 months without mixing.
