Abstract
An adhesive mixture includes a block copolymer hot melt adhesive and particles of a vapor corrosion inhibitor mixed therein to protect products against corrosion. The adhesive is used to seal flaps of containers together, secure carpet to the floor of a vehicle, secure nonwoven fabric to a shrink film so that the additive is released when the shrink film is shrunk around a product to be protected, or used as an adhesive on a tape, so that the product is protected when the tape is wrapped around the product.
Claims11
Adhesive mixture comprising a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, said vapor corrosion inhibitor being in the form of particles suspended in said adhesive composition, said particles having a maximum dimension of less than about 30 microns.
Adhesive mixture for securing packaging components together and for delivering an additive to a product within a volume defined by the packaging components comprising a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, said vapor corrosion inhibitor being in the form of particles suspended in said adhesive composition, said particles having a maximum dimension of less than about 30 microns.
Method of manufacturing an adhesive mixture comprising the steps of reducing the particle size of the particles of a particulate vapor corrosion inhibitor to a maximum dimension of about 30 microns, and then mixing the vapor corrosion inhibitor with a block copolymer hot melt adhesive.
