Other Silicone Additives LRA-2

short description:

Siemtcoat®, Low release force modifier for release coating system. It is active silicone polymer which could lower the release force by different dosage in the system. High performance silicone coatings and additives bring unique properties to coated paper and film for technical application. Silicone release coatings for paper and films are the perfect solution to protect your self-adhesive materials and also offer high non-stick performance for a number of applications.

Application

The LRA-2 is special design for lower the release force after release coating cured. It could be adding to release coating system (both solvent base or solventless system) during the mixing process. After cured, it could be achieved lower release force and with lower impact to the subsequence adhesive. This modifier would be efficiency for different type adhesive.

Advantage

● Active low release force additive

● Low silicone migration

● Suit for different type adhesive system.

PackageProcessing

When application LRA-2 into Siemtcoat system, please following bellow ratio and mixing process:
  1. Weight the main polymer

100p

  1. Weight low release force additive LRA-2 base on need                              0.5-4p
  2. Mix the additive even
   
  1. Weight the crosslinker
                                       0.5-5p
  1. Mix the crosslinker and make sure it was dispenser well
  2. Weight the catalyst Siemtcoat 5000 and add in during mixing                       0.7-2p
 
Attention: do not mix the crosslinker and catalyst directly as dramatic reaction would happen
  1. Mix until the catalyst even
