Adhesion composition and textile materials and articles treated therewith
11066582 · 2021-07-20 · ·

This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.

Method for producing thermosetting phenolic resins and phenolic resins obtainable by the method

A method for producing thermosetting phenolic resins includes the step of reacting a polycondensable phenolic compound with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products. The HMF includes at least one HMF oligomer, and the reaction step is carried out at pH values greater than 7 for more than 60 minutes. Further, thermosetting phenolic resins may be used for producing a wood composite material.
