Simacryl® ETC-401 is designed to be used in laminating and pressure sensitive adhesives formulations. In some cases it is recommended to use 5% of NaoH or Ammonia for raising the pH since it causes increase in cohesive strength. Although increasing pH can also be achieved by adding some additives like Texanol. It should be noted that prolonged storage in pH over 8, may change the color of Simactyl® ETC-401. 0.05-0.2% wetting agent is recommended to overcome wetting problems. Adhesives based on Simacryl® ETC-401 can be applied usual coating systems such as: doctor blade, wire-wound roll, air knife, reverse roll coating, reverse gravure coating, curtain coating and jet applicator. We would suggest adding preservatives to pressure sensitive adhesives formulations containing simacryl® ETC-401 to protect the system from microbial attack.
In order to prevent contamination of pressure sensitive adhesive, sure that the bulk cap, is closed perfectly after each usage and store it above 5 OC.
High resistance to shear, good peel adhesion and acceptable cohesion are the characteristics of Simacryl® ETC-401.
