                                 Silicone glue for glass protective film 

                                 (Good air dispersing capacity) KL-9310 B


Products Description

KL-9310 B is heat and fast cured type of silicone adhesive,combine with platinum catalysts P4000, tackifier KL-298, KL -6600 used together,no primer needed.,good flowing capability before cured ,The cured silicone adhesive has a good adhesion to stick with PET base material. After cured,has good adhesion strength, excellent air dispersing capacity,high transparency, no adhesive residue, high temperature resistance, high humidity, can directly replace the same level products of Dow Corning and KCC products. 

Mainly applied to mobile phone toughened glass protective film,PET silicone protective film series products.

(for example, coated 50μm stripping force 5g/25 mm)

1.(1) Slit spraying method

Advise to use solid content is 30% of the formula ratio (weight ratio) Solvent:KL-298:9310B:6600:P4000 =100:6:70:30:1.5

 (2) Comma blade coating method

Advise to use solid content is 35% of the formula ratio (weight ratio) Solvent:KL-298:9310B:6600:P4000 =100:6:70:30:1.5

2. Taking material according to proportion, first KL - 298 and solvent mixed evenly, and then add in turn 9310B→6600→P4000 , to achieve uniform mixture stirring 20 minutes 

3. Coating uniformity of silicone adhesive on the PET film surface by coating method or rolling process.

4. Testing at laboratory coating method 10 μm baking 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 dry adhesive thickness of the coating when 30μm, glue baking time control between 90 to 100 seconds ,the dry adhesive thickness of the coating when 50μm,glue baking time should be controlled in 120 ~ 150 seconds is advisable.Please change according to the specific equipment and operation method.

*This data is for reference only, actual stripping force is related to the production process, When using need to confirm and necessary adjustments. Our company will not bear any costs after using this product with direct or indirect losses caused . Please contact our company salesman for  more information.


1,The solvent is better to choose mixed solvent,Such as xylene:butanone=80:20 or toluene:butanone=1:1

2,The application ratio should be adjusted appropriate to different materials, the thickness of coating and weather conditions

(temperature and humidness). The application ratio should be increase platinum catalysts 5%~10% based raw ratio at hot

and humid conditions.  KL - 298 is volatile,for a long time place will thicken,in use process need to adjust the adding

proportion according to the proportion of volatile,otherwise the stripping force will increase .

3,The base material surface by adhesive through corona treatment,Cleaning base materials and keep it dry, no dust and oil.

 Controlling and checking the viscosity during the coating process. Pay attention to have enough quantity for once and  make it deeply cured.

4, Keep in a good and suitable condition for coating. The working shop should be dust-free at 2535℃ and humidity

controlled in 15 ~ 60%.Too much dust will cause adverse to increase, Low over temperature will cause poor flow flat  and

adhesion strength decline , Large over humidity will cause shrinkage cavity of film. Low over humidity of the electrostatic

potential safety hazard,appear on the surface of white and ripple phenomenon.

5, The mixed silicone adhesive should be used up within 6 hours, if high viscosity happens or appear gel,should stop using.

6,The adhesive after mixture containing volatile solvent,the work place should be ventilated and workers should wear labor

 protection tools during the coating process. Away from flame, high temperature and pay attention to static electricity.

7,Please read the product safety instructions before using.
