Application – Remarks

Centari® 500, Centari® 500 HB and 1200S:
421R can be used with the standard thinner and activator to give optimum balance in drying. Maximum amount of 421R is 100 % replacement of the thinner in ready-for-use.

Imron® 700:
421R can replace AU370 with maximum 50 %.

1200S and 3050S:

• Maximum amount of 421R is 10 % in volume ready-for-use.
• Do not use 421R together with 256S or XK203.
• Close container after use. This prevents the solvents to evaporate and to lose strength.
