A modem PUR Adhesive is able with both a pretreatment and a post-treatment unit

Recommended Posts

A modem PUR Adhesive is able with both a pretreatment and a post-treatment unit. From the plan presented here, the afterward observations were made.

The college the activated candelabrum adeptness and the thicker the coating, the college the credible action and polarity of the low physique polyethylene (PE-LD) surface.

If a top candelabrum adeptness was activated to the coating, abandoned the arctic basal of the credible action was increased.

The credible action decreased acutely as a action of aging, but remained added or beneath connected afterwards about 2 weeks' accumulator time.

The acquaintance angles of baptize on cardboard activated able-bodied with the oxygen accommodation (determined by ESCA) and with the activated candelabrum power.

The polarities of both cardboard and paperboard added as a action of the activated candelabrum power. Candelabrum pretreatment of cardboard and paperboard bigger their adherence to PE-LD remarkably.

The adherence of the polypropylene (PP) homopolymer is based added on automated alternation than on interfacial bonding. On the added hand, the acerbic pretreatments of the Food Packaging Glue substrates decidedly answer the adherence of the PP copolymer.
