贮         存
  如果正确贮存并且保存在最初密封的包装中,在室温下,保质期为1年;
  本产品应放置于通风,清洁,避光,室温的场所。
 
应         用
  用光谱测定其活性,在水中稳定性较好,低毒。SD818-1是一种多用途防腐剂。
  SD818-1的活性光谱图覆盖了细菌,包括甲醛残留物、菌类、酵母和藻类等。
  SD818-1可以在生产过程中任何阶段加入,但最好还是先加入进料液中。如果生产过程中温度大于70℃,PH大于9,就需要在最后加入。为了保护产品要注意均一地加入防腐剂。因其粘度较低,SD818-1可以不经稀释使用,当然也可以用水稀释后再使用。
 

建议添加量:0.02-0.1%
PH适用范围:1.0-8.0
使用温度:<60℃

  将SD818-1应用在新产品中或是有新的应用时,预先建立复杂的测试系统是十分有必要的。

  Composition:Aqueous, ormaldehyde-free formulation of various isothiazolinones
  Description:Clear, light yellow to pale green, almost odourless liquid
 
User
  For the preservation of aqueous coatings, polymer dispersions, filler suspensions, solutions and dispersions of adhesives and thickeners, concrete additives, oil emulsions, polishes etc.
For the preservation of surfactants, cleaners and disinfectants.
 
Specification
  (HPLC): (1.5±0.05)%
 
Storage
  If correctly stored and kept in the original sealed package at room temperature the shelf life is 1 year.
  The product should be protected from heat(temperature should not exceed 40℃)and from frost.
 
Applications
  With its broad spectrum of activity, good solubility in water and low acute toxicity, Preventol D 7 is a versatile preservative which is easy to use.
  Preventol D 7’s spectrum of activity covers bacteria, including formaldehyde-resistant species, fungi, yeast and algae.
  Preventol D 7 can be incorporated at any stage of the production process but is best added to the feedwater first. If higher Temperatures(>40℃)or pH(>9) Values are likely to occur during the manufacturing process, the product should be added at the end of the process, however. In this case take care to homogeneously distribute the preservative within the product to be protected. Because of its low viscosity, Preventol D 7 can be used undiluted or with water added.
 

The product can also be pre-dissolved in alcohols or alcohol/water mixtures. The use of Preventol D 7 in the preservation of aqueous formulations does not generally cause any undesirable side-effects. In contrast to preservatives containing active ingredients which split off formaldehyde, Preventol D 7 is highly suitable for the preservation of products which contain protein (e.g.casein).

  It is advisable to carry out compatibility tests before Preventol D 7 is used in new products or applications.
