Typical substrates:
Technical data:
| Item: | NEL-6638N |
| Appearance | Colorless to pale yellow liquid in room temperature |
| Viscosity | 200~800 mpa.s(25℃) |
| Drying | 15-30s |
Instructions:
1.This product is quick-drying PU adhesive, by heating to melt after the adhesive layer is dried(the recommended mold temperature is 180℃) then bonding. If the molding temperature is too high, finished product will be easy to debond. According to the thickness of foam, setup different molding temperature and molding time.
2.This product is suitable for spraying, roller coating. The appropriate caliber of spray gun is 1.3-2.0mm and the pressure should not be less than 4kg, depending on different demands.
3.If product viscosity is too large, the proper amount of ketone solvents or banana oil can be added for dilution.
When do the spraying, choose appropriate spraying distance according to requirement. The adhesive appears punctiform if the spray gun is close to the coated surface; if far away it appears filiform.
4.If the higher bonding strength or better heating resistance is required, 2%-5% isocyanate curing agent (60% content) can be added. But it may not restore after lamination and depending on the amount of curing agent dosage.
Storage:
1.This product should be transported in well-sealed packaging to avoid intense collision and sudden hot. Store in a well ventilated place and keep it away from fire. The appropriate storage temperature should be above 5℃ in winter, crystallization may occur if below 0℃. It can be used after being heated and stirred (suggest heating by hot water but firing is not allowed), doesn’t effect the performance.
2.6 months shelf time from the production date in original package.
Package:
15kg/drum；
