Henkel Granted China Patent for Two-Component Fluid Dispensing System

Henkel Adhesive Technologies is pleased to announce that the State Intellectual Property Office of the P.R.C. (SIPO) has granted China Patent No. CN 203525578 U in recognition of the company’s innovation, relating to a fluid dispensing system that provides precision ratio metering and fluid flow shut-off of a mixed fluid.

The technology, applied commercially in the portfolio of Loctite dispensing systems including Loctite 4530-HC, Loctite 5060PC, Loctite RB22 and Loctite MM20, facilitates the precise metering of two fluids to form a mixture such as an epoxy, acrylate, polyurethane or silicone to be used as an adhesive. The patented technology from Henkel provides for exact metering of the two components in precise ratios, resulting in the desired adhesive chemical composition.

Henkel’s invention solves the problems of inaccurate ratio dispensing and ‘drooling’ or dripping of the fluid when flow stops. This is achieved through the combined use of a volumetric displacement, dual rotor pump for metering two fluids, and an anti-drip valve for precisely controlling the fluid shut-off.
