WAKNER recently presented two hydrophobic HDK-pyrogenic silicas and VAE dispersions
for adhesive dispensing at Adhesives & Sealants China 2017.
HDK?H30RY is a hydrophobic silica modified with methacrylic acid that chemically bonds into the resin network structure to improve the mechanical properties and scratch resistance of vinyl, polyester or acrylate-based systems, opening up a wide range of applications
such as coatings, adhesives and sealants.
In addition, it improves the performance of
dental fillings and nail gels.
HDK?H20RH is a high specific surface area hydrophobic silica
retreated with alkyl silanes.
As a siloxane-free additive with excellent rheological properties in polar systems, it can extend the storage time of epoxy resins and two-component adhesive curing agents, especially to improve the storage stability
of amine curing agents.
Applications include automotive adhesives, half-shell binders for wind turbine blades and chemical anchors
.
VINNAPAS? EP 6420 is WACKER's new product for the formulation of water-based adhesives for high-quality paper and paper packaging, especially for dispensing machines
.
It has excellent nozzle workability when using nozzle coating, is not easy to agglomerate, stable operation, fast drying speed, and easy
cleaning.
It is also suitable for roller coating machines and increases productivity
.
