摘要:
Method for making lignocellulosic composites by adhering lignocellulosic substrates together. A first variant of the method involves using an adhesive composition that comprises a reaction product of (i) first ingredient selected from a soy protein or lignin and (ii) at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein. A second variant of the method involves using an adhesive composition that comprises a reaction product of (i) a protein or lignin, (ii) a first compound that includes at least one amine, amide, imine, imide or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the protein and (iii) a curing agent.
摘要:
A low application temperature, high heat resistant hot melt adhesive comprising an ethylene n-butyl acrylate copolymer having a melt index (MI) of 750 grams/10 minutes or higher and an ethylene vinyl acetate (EVA) polymer having a MI of 750 grams/10 minutes or higher are particularly well suited for case and carton sealing operations.
