HAA powder crosslinking agent
HAA type reactivity than TGIC powder, low temperature crosslinking (160 ℃ / 15 min), stability is better than TGIC powder storage layer, weatherability TGIC and can be used for spraying the friction, less dosage of crosslinking agent than TGIC.
However, the HAA powder was delivered with low molecular compound, the coating was too thick and easy to appear pinhole, the baking heat resistance was worse than the TGIC, the coating was yellow, the incinerator was not complete, and the corrosion resistance was poor.
As domestic polyester with the HAA gradually improve, improve sexual intercourse T105M, degassing agent and other auxiliaries, HAA type chemical resistance, heat resistance, coating pinhole and get better performance, comprehensive performance can be comparable to TGIC type completely.
Economic cooperation into yellow - appearance of product is white powder or granule, hydroxyl equivalent to 82 + 2 g/eq, non-volatile portion of 99.0% or higher, melting range 120 ~ 130 ℃.
The meaning of the HAA powder substitution. TGIC type powder, besides itself toxicity gradually restricted the powder storage stability is one of a lethal performance attenuation and fast, in the summer, long distance and long time transportation (especially export) easily in the cluster, causing powder spraying, performance attenuation; The performance attenuation is fast and the mechanical property decreases rapidly after long storage. In addition, the TGIC powder crosslinking temperature is too high in the requirement of energy saving and consumption of carbon emission, and the value of its integrated cost is gradually recognized by the powder customers.
And HAA type powder just solved the powder storage of the use of transportation problem, and the implementation of HAA type instead of TGIC type without changing any construction facilities need to decrease the temperature of drying tunnel construction, which greatly reduce the energy consumption and reduce carbon emissions, its long-term comprehensive cost and social benefit is very obvious.
As foreign strict limits on TGIC gradually, TGIC foreseeable will increasingly become the mainstream products, and the development of substitutes for HAA type varieties in China in accordance with China's national conditions, in particular, the health, saving energy and reducing consumption, and the significance of reducing carbon emissions, many users have powder in pay attention to the value of HAA type powder, the rapid development of HAA type powder is just around the corner.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
HAA environmental powder coating in home appliance application. Our country HAA type environmental protection powder coating mainly starts in the home appliance field, and becomes the mainstream home appliance powder substitute breed.
Has successfully developed a comprehensive performance with TGIC type weather resistance type powder considerable HAA hou powder, and successfully used in some large home appliance enterprises such as gree electric appliances fully implement alternative for HAA type powder 100%. Other home appliance companies have also come to recognize the importance of substitution and have begun to act.
At present, the domestic HAA environment-resistant powder varieties are more than 98% in household appliances. The home appliance USES HAA environmental protection type powder resistant powder to become the leader of our country HAA type alternative powder coating.
HAA environmental weather resistance type powder coating instead of TGIC powder coating become the inevitable trend in our country, not only is the request of environmental protection and human health, and energy saving and reduce carbon emissions is a necessary requirement.
As long as the industry chain (raw materials, manufacturing enterprises and powder) of people with lofty ideals to fully recognize HAA environmental weather resistance replace the importance and urgency of powder coating, lead to competition in the industry, leading industry and environmental protection, saving energy and reducing consumption of the standard, and promote the development of the industry better, their own responsibility for environmental protection, human health, you need to pay a practical action, upstream and downstream joint efforts, the technical problems will not be a problem. HAA environment-friendly powder coating not only blooms in the field of home appliances, but also promotes the general development of other powder areas as soon as possible.
