Processing
Slight separation may occur in Part A during transportation and storage. Ensure that the Part A is completely homogenised before processing begins. Mix the two parts thoroughly as per mixing ratio and apply by brush or pasting knife on both parts. Make sure that the model boards are clean and free of dust, dirt and grease. For best results, it is recommended that the two components are at least 20°C before mixing.

Mixture-ratio A to B:
2 to 1 (by weight)

Curing time:
approx. 12 - 18 hours at 25°C

Processing / Application Time (100 – 300 g, 25°C):
approx. 7-12 minutes

+ - Storage Click to collapse
NECURON® K4-A and K4-B should be stored in original, unopened containers between 20 and 25°C. NECURON® K4-B may crystallise partially or completely if not stored at above 20°C. Like all polyurethanes, both components are moisture sensitive. Moisture absorption will cause excessive aeration in cast parts. KEEP THE PACKING TIGHTLY SEALED WHEN NOT IN USE.

If stored under the above conditions, will have a shelf life of 6 months, from the date of production.
