How to calculate NCO & OH required in kg?
Someone asked me if they have Adhesive ratio of 100:55 (Dow 2 component Adhesive).
Adhesive total Quantity required 100 kg for a particular job.
It’s a Very simple and basic Calculation.
NCO : OH
100 : 55
NCO = FINAL QUANTITY X NCO RATIO ÷ ( NCO RATIO + OH RATIO)
100 X 100 ÷ (100+55) = 64.52 kg
OH = QUANTITY X OH RATIO ÷ (NCO RATIO + OH RATIO)
100 X 55 ÷ (100+55) = 35.48 kg
