An adhesive system for preparing lignocellulosic composites comprising a) an aqueous primer composition and, b) a polyurethane adhesive composition, wherein said aqueous primer composition comprises: from 0 to 25 wt. %, by weight of the composition, of polyol selected from the group consisting of water soluble polyols, water dispersible polyols, water emulsifiable polyols and mixtures thereof, wherein said polyols have a molecular weight less than 5000 daltons; and, up to 10 wt. %, by weight of the composition, of surfactant selected from the group consisting of water soluble surfactants, water emulsifiable surfactants and mixtures thereof, with the proviso that the aqueous primer composition must comprise at least one of said polyol or a surfactant having hydroxyl functionality and a molecular weight of less than 5000 daltons.

Adhesive system for preparing lignocellulosic composites

A novel adhesive that finds use in a cold corrugating system has a 5 second tack at a temperature of 160&#xb0; F. of at least 50&#xb1;2 grams.

Corrugating adhesive and use thereof

The invention provides the art with an adhesive that may advantageously be used in the manufacture of water resistant paperboard products, such as laminated board and corrugated board. The adhesive has the required tack, water resistance and viscosity that allows its use at commercial speeds in a cold corrugating process.

Water resistant adhesive and methods of use

A foamable crosslinkable composition particularly useful as a foamed adhesive or coating.

Adhesive composition

Corrugating adhesives comprising a starch, an alkali, water and a surfactant allow the user to control the amount of adhesive applied, minimize warpage of the final corrugated board and allows equipment to run faster and in a more efficient manner.
