Rubber resin compositions are often used to bond polyolefin and other low energy substrates

A typical acrylic pressure-sensitive adhesive is an alkyl ester monomer, a functional monomer such as acrylic acid.

Copolymers can be cross-linked with, for example, aluminum chelators. These adhesives are generally deficient for low-energy surfaces.

Lack of adhesion, but these adhesives can be improved by adding rosin esters to the low-energy surface it works. But at the same time lead to the loss of heat resistance and aging resistance. Even if it hurts well with good aging resistance, the viscosifying acrylic dispersion is also sufficient for some uses, such as most paper labels, and has actually become the dominant paper label technology. But these enhanced propenes.

Acid binders do not have sufficient resistance to degradation required for most cartographic and industrial tape applications, where acrylic solutions are commonly used.

Rubber resin compositions are often used to bond polyolefin and other low-energy substrates.

The compound is a natural rubber or styrene block copolymer with rosin esters. These compositions have advantages

It has good adhesion and bond strength but is subject to oxidation and degradation caused by ultraviolet irradiation

The use will fade and age and lose viscosity. A fully hydrogenated composition of rubber and resin, except to be added into.

In addition, basically does not have the required cohesiveness.

The United States patent once disclosed a rubber acrylic pressure-sensitive adhesive mix only good.

Good UV and aging resistance and adhesion to non-polar surfaces. In spite of the ability with these advances, improvements are still needed to prepare polymer compositions that are pressure-sensitive adhesives, such as industrial tape, transfer film, and exterior graphics, where adhesivities and chemical resistance are sufficient to work with low-energy difficult-to-bond surfaces. The invention is the solution to this need.
