Experts in professional adhesive applications

Adhesives

We don’t simply provide off-the-shelf products, and as a result customers profit from our excellence in determining tailor-made solutions for custom applications, particularly in the field of adhesives. Every surface to be bonded has its own requirements, and WEBER & SCHAER has the experience and know-how needed to achieve the best possible result.

High-quality adhesives to suit any requirement

In order to do justice to the many requirements and individual requests that our adhesives customers have, WEBER & SCHAER is now offering a wide range of products that include various hydrocarbon and natural resins. In addition to natural rubber, our range of products includes other elastomers for this highly interesting and highly complex field of applications – from styrene block copolymers (SBC), styrene-butadiene rubbers and latices (SBR) all the way to synthetic polyisoprene rubber and isoprene latex (IR).

Once an optimum elastomer has been found, the second step is usually to combine it with a suitable tackifier resin so that the characteristics desired for custom adhesive tapes, liquid adhesives or HM adhesives can be achieved.

WEBER & SCHAER has also been particularly focused on a special field in recent years for which there is an increasingly emerging trend on the market: water-based adhesives based on natural latex.
Adhesives actually constitute a very traditional field of applications for natural rubber and natural latex products (NR) like the ones we sell. And we have succeeded in acquiring detailed expertise in needs-based formulations and establishing a wide variety of ready-made compounds for adhesive tape applications.

Various water-based antidegradants and anti-aging agents in powder form round off our adhesive portfolio. We also sell all the common rubber grades in granulate form in different size distributions and with varying partitioning agents.
