General Use Instructions
ZB is a good flowing,readily dispersible,high whiteness powder, which does not detract from bright colors and
pure whites.
ZB is mainly used as fire retardant, biocide/fungicide and anti corrosion.
ZB is mainly dispersed into wood, wood plastics composites (WPC), coating systems (in-can preservative and dry film fungicide), plastics and rubber as a corrosion inhibitor and biocide, So, it is incorporated during the pigment dispersion cycle in the coating preparation process.
ZB400 is standard grade that can meet most the applications of Zinc Borate.
FIRE RETARDANT
In rigid PVC, ZB can be used solely to get excellent fire retardant performance. In flexible PVC,PP, Epoxy, rubber etc polymers, ZB is one good synergistic fire retardant with Antimony Oxide,Al(OH)3,Mg(OH)3,or Bromine fire retardants
to improve fire retardant performance, it has excellent functions as smoke suppressant,char promotion and adjust the balance of flame retardant properties versus mechanical, electrical and other properties.
Normal dose in polymer as fire retardant is 1-10phr.
CORROSSION INHIBITOR
ZB can be used as a corrosion inhibitor in both organic solvent-based and water-borne coatings.ZB can have the coatings effectively be more economical, higher performance without Chromium, Lead, or Barium-based pigments.ZB can be also used effectively to replace Zinc Chromate in many formulations by equal weight.
ZB has good synergism to enhance performance when it is combined withnormal corrosion inhibitive pigments, such asZinc Phosphate,Barium Metaborate.The crystal water in ZB is not reactive form and dehydrates at up to 300ºC, so it can be used in some high temperature baking systems. Normal formulation range is 0.03-0.3g/ml.
WOOD AND WOOD PLASTICS COMPOSITES
ZB can be wood and wood composites preservative to protect from wood destroying organisms in above-ground applications.ZB is added prior to or during the blending process, it will achieve a thorough and uniform distribution throughout the composite material. ZB will control the growth of white (e.g.Trametes Versicolor) and brown (e.g.Gloeophyllum Trabeum) rot decay fungi, it also helps protect composite materials from damage
caused by wood destroying insects.
The ability of wood and wood-plastic composite to resist wood destroying organisms depends on wood species, resin type,resin and wax content, production method, exposure hazard and wood preservatives. ZB dose must not exceed 8 %( w/w). When ZB dose exceed 1.5 %( w/w) in wood composite, it may be necessary to use additional adhesive to enhance strength.
COATING SYSTEMS
In-Can Preservative:ZB has function as in-can preservative, the advised rate in formulation is 0.03-0.3g/ml.
Dry Film Fungicide: ZB has also function as a dry film fungicide. It can control mixed fungi such as Aspergillus Niger, Penicillium Funiculosum,Chaetomium Globosum,Trichoderma (Gliocladium) virens and Aureobasidium Pullulans.
The advised rate in formulation of dry film coating fungicide is 0.03-0.3g/ml.
Fertilizer
Because high content of Boron element, ZB is also used as fertilizer to improve the growth of some special trees, such aseucalyptus,heave brasiliensis.
CERAMIC FRIT
ZB can replace Zinc Oxide and Boric Acid to make composite frit without water.Composite ZB frit has high efficiency to reduce the usage quantity and can tremendously reduce the sinter temperature.At 980-1000ºC,it can sinter to kinds of low-temp glazes. Moreover, ZB frit is easy to sinter to glass phase to improve ceramic strength and the slurry performance.
Basing on ZB's property as fungicide, it will protect the ceramic surface from kinds of fungi, bacteria.
