Antibacterial anti-mold agent SP is an anti-bacterial and anti-mold agent developed by our company. It has the advantages of high safety, good heat resistance and good chemical stability, and can be added to all kinds of paints, emulsions, adhesives, rubber and plastics to play the role of anti-mold and anti-bacterial.
Under standard film forming conditions (=23.89℃, RH-50%), the organic acid of the drier is different, and its drier performance is similar. Only use the ring at a lower temperature (7.22℃) or a higher temperature (32.22℃). Medium oil alkyd paint with alkanoic acid soap will dry faster than oleic acid soap. The metal composition of the drier is different, which is more affected by the film-forming conditions. For example, the calcium drier is susceptible to the influence of humidity and the dryness is obviously delayed.
Depending on the oil level and oil type of alkyd resin, the dryness of the coating film is also affected by the film-forming conditions. For example, the dryness of long-oil alkyd varnishes accelerates correspondingly with the increase of temperature, at high humidity (RH=90%) The dryness is not delayed, but the dryness of the medium oil alkyd varnish at high humidity (RH=90%) is delayed.
The influence of paint components The paint components have a certain influence on the effect of the drier, especially after the long-term storage of the paint, the dryness of the drier will be significantly reduced, and the dryness of the coating film will be slowed down, which is often called “loss of drying. “.
Lead-containing pigments such as Huang Dan, Hong Dan, lead-containing zinc oxide, etc. can form lead soaps with fatty acids in paints and have drier properties. Phthalocyanine pigments also have certain drier properties, which are beneficial to drier properties. However, some pigments, such as carbon black and titanium white, have the ability to adsorb driers, which reduces their dryness.
The drier is adsorbed by the pigment, instead of forming a monomolecular carnauba wax on leather layer on its surface, it is adsorbed on the active part of the pigment surface. The strength of its adsorption capacity varies with the type and spatial configuration of the pigment, the type and acid value of the binder, and the presence of moisture impurities.
