Mergal®K14plus is a broad-spectrum in-can protectant that prevents degradation and deterioration of aqueous systems due to bacteria, fungi and yeast.

Mergal®K14plus is widely used for in-can protection of aqueous systems such as: paints, plasters, polymer dispersions, adhesives, sealants, inks, detergents, household cleaners, fountain solutions, colorants and other industrial applications.

 

 

 

 

 

 

 

 

 

 

 

 

An example of painting that also uses spraying. When electrostatic spraying is used, in order to improve the coating performance of the electrostatic coating on the substrate, the conductivity of the coating must be adjusted. At this time, the least impact on the coating formulation and the fastest way is Add electrostatic coating conductivity enhancer. After stirring and dispersing uniformly, the coating used for general spraying can be converted into the coating required for electrostatic spraying. The required addition amount can be measured with a conductivity meter.

The first consideration for drying and curing is the crosslinking and curing reaction mode of the resin/curing agent, the standing time after coating, and the baking conditions of the drying tunnel. The reaction mode of the base material determines the required choice of accelerator. For example: the wax powder curing accelerator of oxidative drying coatings is divided into surface drying drier and inner drying drier. The surface drying driers mainly include cobalt and manganese driers, and the inner drying driers mainly include zinc, calcium, zirconium and so on. For the curing reaction of amino resin and hydrocarbon-based resin, acid catalysts such as p-toluenesulfonic acid (and closed type), modified sulfonic acid (and closed type) and acids can be used. As for the polyurethane curing reaction coating system, various organotin, bismuth, tertiary amines and other accelerators can be used to shorten the baking or curing time. For unsaturated polyesters, peroxides are used as initiators, together with drills or organic tertiary amines. As a curing accelerator. Two-component epoxy resin systems that cure at room temperature generally choose tertiary amines, secondary amines, imidazoles and carboxylates. In addition, cationic compounds of Lewis acid and Bronsted acid can also be selected. The application of these curing accelerators depends on the additives Variety and the use of the technical instructions provided by the supplier can not only avoid affecting the storage stability of the coating, but also prevent danger from occurring.
