CYCAT® 4045

CYCAT® 4045 CATALYST is an amine blocked para-toluene sulfonic acid catalyst. It is recommended for accelerating the cure response of amino crosslinking resins while providing improved formulation package stability compared with the un-blocked para-toluene sulfonic acid CYCAT® 4045 CATALYST It is especially recommended for use with highly alkylated amino crosslinking resins. It provides excellent stability in high solids and waterborne systems, and in the latter it can be added without causing binder precipitation, which can often occur due to a drop in pH.

Applications & Uses

Dosage Information
  • CYCAT® 4045 CATALYST contains 20% active acid and has an equivalent acid number of 60-70.
  • Therefore, it is 50% less active than the un-blocked CYCAT 4040 catalyst.
  • Therefore, in comparison with CYCAT 4040 catalyst it is recommended that twice the level of CYCAT® 4045 CATALYST be used to provide approximately the same cure response.
  • In systems containing highly alkylated amino crosslinking resins such as CYMEL® 303 LF resin in combination with hydroxyl or carboxy functional acrylic or polyester resins, the following starting point levels of CYCAT® 4045 CATALYST are recommended:
Polymer type Cure Temperature (°C) Catalyst Level (% catalyst solution based on total resin solids)

Typical Coating Characteristics
  • System: White high solids acrylic enamel, 73% NV by wt, Pigment/Binder=80/100
  • Binder:: Acryloid AT-400 (Product of Rohm & Haas) acrylic resin/CYMEL 303 resin= 80/20 (solids wt ratio)
  • Catalyst: Equivalent to 1% CYCAT 4040 catalyst on TRS
  • Cure: 20 minutes at 125°C

Properties

Technical Details & Test Data

Catalysis Information
  • In order to prevent recrystallization of the acid, a sufficiently high level of alcohol should be present in the total solvent system of the formulation.
  • Recrystallized acid can cause a reduction in cure response and may create local areas of high acidity that could cause the formation of gel structures.
  • Therefore, it is suggested that CYCAT® 4045 CATALYST be diluted approximately 1:1 with an alcohol before adding to the final formulation.
