Product overview
KEPERCAT®-545 is strong acid type acid catalyst for baking paints,It can effectively improve the hardness and processing properties，water resistance and corrosion resistance of the paint film.
Physical data
1. Effective ingredient: Dodecylbenzene sulfonate amine salt
2. Content: 25%
3. Solvent: Isopropyl alcohol
Product features
1.Strong acid type, minimum curing temperature: 120℃, best curing temperature: 130-140℃.excellent stability, high temperature baking does not turn yellow, low temperature environment will not precipitate.
