Product:Reactive Tertiary Amine Co-initiator
L-8120 is a 2-functional tertiary amine co-initiator with a special structure of acrylic acid acyloxy group with very low odor. It can provide a large amount of active hydrogen, effectively avoid oxygen inhibition, increase the curing speed, and show excellent surface drying performance when used in formulas. Compared with tertiary amine products of the same type, the appearance color is very light, and the color change is very small during storage; and compared with tertiary amine products of the same type, it shows excellent yellowing resistance.

Storage, shelf time and Packing
To prevent the product from polymerization and gelling, please keep it sealed and away from heat and light. Recommended storage temperature is not higher than 30°C. Unused products must be sealed and stored in a timely manner and cannot be stored in the open. Safe storage time is 6 months at room temperature( 25ºC) and under ventilation. 25KG/200KG/barrel.
Tips: L-8120 can increase the cross-linking density of the coating and also increase the flexibility of the coating.
