First introduction of food contact grade raw material formula
It is understood that Sanshu BB paint is the first wall paint with BASF food contact grade emulsion as raw material and food contact grade formula in domestic industry. Not only passed a number of strict environmental protection certifications in Europe and America, but also passed the relevant standards testing of food contact materials of FDA in the United States. It is a high-end wall paint that meets FDA food contact level and can kiss TA. In addition, Sanshu is the exclusive supplier of official coatings for Beijing 2022 Winter Olympics and Paralympics.

FDA us food and drug administration
The full name of FDA is the FoodandDrugAdministration in the United States, and it is the most authoritative auditing organization in the international food and pharmaceutical industry at present. Its food contact standard is also called the most valuable food contact health and safety standard in the world.
Define what food contact materials are.
Food contact material refers to a kind of material that will directly, indirectly or possibly contact with food, but does not constitute the food itself, such as tableware, lunch boxes, baby products and so on. In the process of contact between ordinary materials and food, harmful substances may migrate into food, while food contact materials that meet the standard requirements can achieve a low level of harmful substances migration. Therefore, the general requirement for the detection of "food contact materials" is to see whether it reaches the safety level of low migration.
Is it reliable to test whether the paint has passed the food contact standard?
The fact that the paint has passed the standards of food contact materials sounds rather mysterious. Adhering to the principle of asking if you don't understand, we sent this Sanshu BB paint to a third-party professional testing institution for testing according to the same standards and methods as brand promotion.

0 1 detection process
Testing standard: FDA 21CFR175.300;
Sample preparation: one side of the coating sample is coated on an aluminum plate;
Detection method: The laboratory uses water, alcohol, n-heptane and other solvents as food simulants, soaks and extracts the coating at a specified temperature, and then dries and weighs it to obtain the total migration of the coating.
02 test results
The results show that the migration of Sanshu BB paint is 0.45mg/ inch, 0.35mg/ inch and 18mg/ inch, which are far below the standard limit. In other words, it does have low migration security. Meet the relevant food contact standards.
03 expert reminder
Wall paint is tested according to the standards of food contact materials, even if it passes the test, it may not be used as food contact materials. Because for this material, each country has a list of materials and additives that are allowed to be used. Only when the raw materials and additives used in coatings meet the requirements of the list can they be used as food contact materials. Of course, if the coating passes this standard test, it shows that it can reach a low migration level in this respect, so it can reduce the migration of harmful substances to a certain extent, improve the safety effect of the home environment, and ensure the safety performance to some extent.
What are the advantages compared with coatings that pass food contact standards?
0 1 flatness observation
Cement fiberboard was painted with BB paint of three trees and high-grade paint of a certain brand. After natural drying for 2 days, the surface of the paint film was observed, and the difference between the two paints was obvious. The paint film of BB paint on the three trees on the left is obviously smooth and delicate. On the other hand, the paint film of the contrast paint on the right has obvious potholes, and the feeling is obvious.
02 wet wipe test
Wet rubbing test is mainly to investigate the stability of paint film. After wiping the paint film 10s with a wet rag, feel the powder drop by hand. From the hand feel, the two paints have no obvious pulverization phenomenon, but from the residual water stains, they have different performances. The water stain of Sanshu BB paint was not obviously dyed white, while the common paint changed color, and the residual water stain was milky white.
03 immersion test
When the coating is in a humid environment for a long time, the inferior coating is easy to mold and fall off. I think friends in the south have a deep understanding. However, the performance of the two coatings compared this time is very good. Soaked in water for 24 hours, no paint came off. However, the water quality of soaking Sanshu BB paint has not changed obviously, while the water pollution of soaking ordinary high-grade paint has increased obviously.
Summary: In fact, there is also a sensory inspection of food contact coating in the national standard, which requires that the surface of the coating is flat, and it does not bubble or fall off after soaking, and the soaking solution is turbid and tasteless. The above three tests further prove that it is not easy to migrate, and it also meets the requirements of food contact material standards. The structural properties of the paint film coated with Sanshu BB paint are stable enough.
How about experiencing the daily performance that everyone is concerned about?
0 1 Easy to scrub
Three common stains in life, tea stains, soy sauce stains and ketchup stains, were selected and smeared on BB paint samples prepared according to normal construction, and then wiped with a clean cloth. The results show that these three stains can be easily wiped clean, and their ability to resist daily stains is very good. However, it should be reminded that the gap of wall paint coating is generally large. If it is stained, it is recommended to deal with it immediately. The longer it takes, the harder it is to scrub.
02 washable
The test of washability is whether the wall paint can maintain the integrity of the paint film after a long period of scrubbing. We painted the BB paint of Sanshu and another contrast wall paint on both sides of the same piece of cement fiberboard, dried it and scrubbed the paint surface at the boundary repeatedly with a wet rag. It can be seen that the surface of the comparative paint is obviously damaged, while the surface of bb paint is only slightly scratched and no damage is found, so it can be seen that this paint is. Scrubbing resistance is also beneficial.
Summarize the higher safety requirements of home improvement and recommend it!
Generally speaking, Uncle BB paint is really hard enough. Facts have proved that it can indeed pass the safety standards of food contact materials and has obvious advantages in safety, environmental protection and performance. If you have higher requirements for home improvement materials, you can really consider it. Especially if there are children at home who are easy to touch and lick by mistake, it is even more recommended.
