If no otherwise stated, all data of this Data Sheets are measured when the temperature is （ 23±2 ） ℃ and the relative humidity（50±5）％.
If no otherwise stated, the content of volatile organic comonents are calculated by formula, show as g/L.
The volume solids of a coating is the ratio of the volume of its dry film to its wet film at the prescriptive coating method and environment.All data are measured according to GB/T 9272-2007 under laboratory conditions.
The data of gloss are measured by 60°angle according to GB/T 9754-2007, the gloss data are classified as follows:
Dry Film Thickness:
The final film thickness coated on the substrate.
Wet Film Thickness:
The initial film thickness coated on the substrate.
According to dry film thickness, the theoretical coverage can be measured from the formula below:
Theoretical Coverage(m 2 / L) =
The product of this data sheets can only use Sunrui thinner. Use other thinner may affect the curing, thus affecting the performance of coatings. If not use prescriptive thinner, Sunrui company will not be responsible.
If the induction period is marked, the coating should be stired and placed some time (depending on the temperature conditions) according to the requirements of data sheets. It can help to improve the application performance of coating.
The drying time is measured according to GB/T 1728-1979 under the typical film thickness. Such as:
Touch dry: Use finger touch the film suface, if feel somewhat sticky but no paint stick to the finger, touch dry can be considered.
Hard dry: The film complete dry.
Actual application process, the dry time may be slightly different, especially when the temperature of the substrate coated varies the environment temperature greatly.
The overcoating data are under normal coditions. Under low temperatures, harsh weather conditions and/or poor ventilation conditions and requirements of higher dry film thickness, the dry time need to be appropriate extend.
The minimum curing time of epoxy coatings is based on the typical film thickness. When the thickness increased by 50%,the curing time be extended 1.5 times; the thickness increased by 100%, the curing time be extended 2.5 times.
Storage period is general more conservative, expired paint may be used, the performance did not decline. However, in actual use, the expired paint need to be conduct a review before used.
The data of flash point is measured by GB/T 5208-1985.
