1. Look at the brand. You should know that there are many putty powder brands on the market, but not all brands are good. Generally, it is recommended to choose the ones with large brands, high popularity and high cost performance ratio, so that the products can be used with complete confidence; Even if there are use problems in the future, the products of big brands are more guaranteed in terms of after-sales.
2. See certification. Generally, the external packaging of regular products will be marked with the executive standard, weight, production date, shelf life, instructions for use, storage precautions and other words, and also ISO certification. If the product you select does not have these basic information, you must not buy such a product.
3. Look at anti-counterfeiting. The putty powder manufacturers with reliable quality have a strong concept of product anti-counterfeiting awareness. In fact, it is also to prevent products from being counterfeited by some poor manufacturers, so there must be anti-counterfeiting measures. The really good products should be pasted with anti-counterfeit marks or digital anti-counterfeit stickers on the packaging. As long as you scrape off the coating and make a phone call, you can distinguish the true from the false.
So far is the method of distinguishing good putty powder from bad putty powder. I believe you have a certain understanding of this, and I hope it can help you.
