X-Link vinyl acrylic latices are completely self-reacting. They crosslink in a three dimensional network... require no thermosetting resins.

Films of the X-Link resins show improved resistance to water, solvent, creep, and heat. These properties re­sult from the three dimensional net­work that is set up during the curing process. A wide range of X-Links are available with film flexibility ranging from very hard to extremely soft and tacky.

Their small particle size, mechani­cal stability and high pigment binding capacity make them ideally suited for many applications, and they have been successfully field tested as coat­ings, binders and saturants. For ex­ample, in exterior coatings they have demonstrated superior durability and adhesion; in non-woven fabrics they have produced excellent washfastness and dry cleaning resistance; as paper saturants they have provided greater versatility in balancing necessary end properties such as wet tensile, stiffness and tear strength.

These are just a few of the many in­dustrial uses for X-Link resins that re­sult from the unusual combination of properties the X-Link family exhibits.

X-Link resins are easy to use As supplied, X-Link resins are low

viscosity latices that dry to clear films. The pH of the latices is approximately 4-5. The crosslinking reaction is not initiated until the film dries. This gives an added advantage of a package stable latex.

As would be expected, heat and/or catalyst accelerates the crosslinking process.

The homogeneous film forms a three dimensional network of molecules bound to one another by chemical bonds rather than just a loosely knit arrangement of crosslinked particles.

The inherent range of flexibilities available in the X-Link resin series is transferred to the final product; in other words, the soft varieties will im­part good drape and soft hand to non-woven fabrics or textile finishes. The harder X-Link resins can be used to produce rigid and semi-rigid products.
