Adhesive consumed – 100 kg
Laminated Meter – 50,000
Coil/Film Size – 1200 mm
Adhesive gsm = (Adhesive Consumed x 1000000) / (Coil x Meter)
Adhesive gsm = (100 x 1000000) / (1200 x 50000) = 1.66 gsm
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
