Curing agents

  Modified cycloaliphatic amines curing agents
Grades: TH7301 | TH7302 | TH7303 | TH7304 | TH7305 | TH7306 | TH7307 | TH7308 | TH7901| TH7902

Modified Cycloaliphatic Amines are room temperature curing agents. Excellent color and lower corrosiveness makes them the preferred choice for self-leveling floorings, primers, top coats, mortars and water-wipeable tile grouts. These Epotec® Curing Agents posses low yellowing tendency and offer good early water spotting resistance.
