KL-6638AB Silicone adhesives for women bras

utohension Pressure-sensitive Silicone Adhesive 

KL-6638-A/B

 

KL-6638-A/B is two components compound. Heat and fast cured type for silicone rubber. The cured silicone adhesive has a good adhesion to stick with EVA,PVC,and fabrics base material and improving the surface Stripping Resistance. 

 

The silicone adhesives are characterized by good levelling property, electrical insulating property, high grade of transparency and easy to clean with water. Mainly used for health care products   women bras and screen protector.

Application Method:

  1. ixing uniformity A and B by a weight ratio of A:B=3:300. If the surface stripping resistance need improving, tackifier KL-6638AB can be mixed appropriate. The specific ratio should according to the real condition.
  2. uniformity of silicone adhesive on the silicone or EVA,PVC ,fabric surface by coating method or rolling process.
  3. ℃ for 540 seconds

 

 

Matters need attention:

1. The application ratio should be adjusted appropriate to different materials, the thickness of coating and weather conditions (temperature and humidness). The application ratio should better increase 5%~10% based raw ratio at hot and humid conditions.

2. Cleaning base materials and keep it dry, free of dust and oil.

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

  1. Keep in a good and suitable condition for coating. The working shop should be dust-free at 25~35℃ and humidity controlled in 15 ~ 60%. Much over dust will cause NG products, Low over  temperature will cause bad levelling property and adhesion strength, Large over humidity will cause shrinkage cavity of film. Low over humidity will cause potential safety hazard and whity by static.

5 .The mixed silicone adhesive should be used up within 1 hour, if high viscosity happens, stop coating at once.

6. The work shop should be ventilated and workers should wear labour protection tools during the coating process. Away from open flame, high temperature and pay attention to static electricity.

7. Please read the product safety instructions before using.

 

Storage:  Stored at room temperature for 6 months without mixing.

 

Packing:    20KG/Barrel、50KG/Barrel
