- Solubility
CYCAT 4045 catalyst is soluble in oxygenated solvents such as alcohols, glycols, glycol ethers and water. It has limited solubility in ketones, esters and hydrocarbon solvents.
- Technology
- CASE Ingredients
- Catalyst Addition
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 aciditiy 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.
- Recommended Levels
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:; (1) : % catalyst solution based on total resin solids
- Storage and Handling
At temperatures from 5 °C to 30 °C storage stability packed in original containers amounts to at least 730 days.
