EMCAT+® EC2B Catalyst is the Part-B component of the EMCAT+ EC2A Acrylic Polymer Coating System.
Composed of low pH epoxy silane compounds, EC2B Catalyst converts the acid pH Part-A resin component of the 2K polymer system into a fully cured film formation within 24-36 hours.
The addition of 10% by liquid volume of EC2B Catalyst into the specific EMCAT+ Part-A resin is required to complete the chemical reaction. Once the Part-A resin is catalyzed the A/B compound will remain functional for an average of 8-12 hours before the blend is no longer a usable viscosity. Post-24 hours of catalyzation will exhibit a solid, inert mass of the A/B blend.

Methods of Addition
Pre-measure EMCAT+ EC2B Catalyst 10% by liquid volume of EMCAT+ EC2A resin to be added into. Gently stir the EMCAT+ EC2A resin to be catalyzed while slowly adding the premeasured EC2B.
DO NOT POUR CATALYST INTO THE RESIN WITHOUT SIMULTANEOUSLY STIRRING THE RESIN AT THE SAME TIME – This will create a sandy/gritty finish if the catalyst is not stirred into the resin while adding.
Continue to stir the A/B resin mixture for 2 minutes. Allow the catalyzed resin to settle and react for a minimum of 30 minutes before using. For best results premix A/B compound 30 minutes before applying. This will ensure optimum chemical reaction time and flow/leveling performance of the coating during spray application. The minimum recommended temperature for use of catalyzed material is 65 degrees F. The optimum drying temperature for EMCAT+ A/B resin compounds is 70F-130F.
Properly catalyzed material will be functional for a maximum of 8-12 hours – after which time the catalyst will begin to gel and become a solid, inert mass. Any unused A/B EMCAT+ resin compound can be disposed of in accordance with local sanitation laws.
Clean-Up Procedures
All Target Coatings EMTECH and EMCAT+® Series finishes cleanup with water. Rinse spray gun fluid handling equipment thoroughly with water after each use. If finish dries to a hard film soak gun parts in an acetone solution to soften the film for easier removal.
Industrial Hygiene Requirements
See accompanying Safety Data Sheet (SDS). Use only in well ventilated areas. Avoid inhaling spray mist. Wear a NIOSH/MSHA approved respirator with organic vapor filter cartridge during spray applications.
Emergency First-Aid
Ingestion:
Administer large amounts of water.
DO NOT induce vomiting.
Seek immediate medical attention.
Inhalation:
Remove exposed person(s) to a well ventilated area. Treat symptomatically.
Eyes:
Flush with fresh water. Seek medical attention.
Skin:
Wash the exposed area with warm, soapy water. Seek medical attention if irritation occurs.
