Application Instructions
1.Opening time as a reference value. The effective working time after adhesive coated will vary with adhesive temperature, operating ambient temperature, heat conduction performance of the bonding material and material temperature.
2.Please check whether the surface of adhesive is cured or not after opening the drum. If yes, please heat and remove.
3.Common adhesive quantity is about 25g/m²(due to materials differences, actual adhesive quantity subjects to confirmation of sample trial), suggest the working temperature of roller coating machine around 100-120℃.
4.Curing rate depending on the thickness of adhesive coated, environment temperature, humidity of material and permeability of material. Typically the curing takes 24 hours at 25℃, 60% relative humidity.
Package
200kg/drum
