Common knowledge of coating: solution to coating film embrittlement when the weather turns cold

Core tip: after coating many things, especially those used for several years, when the weather is cold, the coating film becomes very brittle, so it is easy to fall Today we're going to collect solutions for this brittle coating Generally easy to use is to add curing agent to dry naturally Note: two component self drying, not one component nitro self drying, nor paint baking This simple operation, but not very practical Change curing agent or mix curing agent For example, we have tried Deqian's 8043 polyester before, which we have folded in half for several times without cracking It's very good It costs a little more But I Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: many things on the paint, especially after a few years, when the weather is cold, the paint film becomes very brittle, so easy to fall Today we're going to collect solutions for this brittle coating Generally easy to use is to add curing agent to dry naturally Note: two component self drying, not one component nitro self drying, nor paint baking This simple operation, but not very practical Change curing agent or mix curing agent For example, we have tried Deqian's 8043 polyester before, which we have folded in half for several times without cracking It's very good It costs a little more But if I just repair paint, I can choose a resin with good adhesion, which can be acrylic or polyester, with HDI curing agent, N75 may be better than 3390 If not, it should be greatly improved if n-3800 curing agent is replaced or combined There is another one we have tested: the cost of HDI elastic curing agent with 3800 is higher than that of aromatic curing agent, which can be used in a small amount On the other hand, we should consider to further improve the flexibility of the main resin. Some plasticizers can be considered in terms of additives, but other side effects, such as decreased chemical resistance, are usually brought about Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
