- Catacure KC
- Catalyst
- GENERALINFORMATION
- Catacure KC is a blocked curing catalyst used in baking paints especially for fully alkylated melamines which need strong catalyst. It can either lower baking temperature or shorten baking time.
- PHYSICALPROPERTIES
- Composition amine salt of p-toluene sulfonic acid
- Appearance colorless to slight yellow or Slight brown liquid
- Non-volatilecontent 23- 25%
- Solvent propylene glycol mono methyl ether/propylene glycol
- Specificgravity ca.1.02
- Refractiveindex 1.436-1.446 (25℃)
- APPLICATIONS
- Solvent based and waterborne acrylic/HMMM
- Polyester/HMMM baking paints
- KEY PROPERTIES
- In general, baking paint based on fully alkylated melamine formaldehyde resin, needs higher baking temperature to ensure fully cross-linking. If lower temperature is expected or limited ,a strong acid catalyst is required to promote reactions. Catacure KC is an additive used for this purpose.
- When added in baking paint, Catacure KC, compared to unblocked P-TSA, shows better storage stability, lower viscosity, less gelation tendency.
- Catacure KC exhibit slower deblocking temperature(130-150℃) ,i.e., lower baking temperature compared to other amine salts of
- P-TSA.
- Catacure KC shows better over-baking yellowing resistance than other amine salt.
- INCORPORATION
- There activity of each back bone and amino resin combination is different, please check optimum dosage according to baking conditions.
- Before used need test coating's stability.
- LEVELS OF USE
- 1-4% based on total formulation.
- SHELFLIFE
- Catacure KC has a shelf life of 18 months from date of manufacture.
- HANDLINGANDSAFETY
- The product requires special care in handling.
