Xylylene Amine（XDA）

Compounded by the ammoxidation of xylene and adding hydrogen, xylylene amine is a sort of chemical material, used as a curing agent of epoxy resin and is one of the best curing agents of low toxicity and normal temperature.It has not only the flexibility of fatty amine,but also all the features of aromatic amine.It is widely used in aerospace war industry,electronic and electrical appliances, instrument,mechanical and chemical industry,plastic mold,the manufacture of vehicle and ship,insulating material,antisepsis material, coating, bonder and sealing agent;at the same time, it can also be used as rubber and ionic adjuvants. Besides, it is an important raw material for synthetic materials like aromatic polyaimde,isocyanate and polyurethane.

SFL antifogging paint

As a new and special coating,antifogging paint is used in humid environment to prevent or delay the fogging phenomenon on the surface of an object. Developed in our institute,SFL antifogging paint can match with the same type of foreign products so as to replace imported antifogging paint. Apart from preventing fogging, it has good antisepsis effect.

With the finishing of SFL antifogging paint ,the equipment will have less corrosion and longer service life,which is advantageous to safe production. Finishing the workshop and walls of the storehouse with this paint can avoid pollution on the products caused by wall mildew. When used in civil residence and office, this paint can purify the living and working environment,which is good to the health.

This paint can be widely used in various fields of both industry and civil. At present, it is mainly used in the following places:

1.Buildings: factory,shop,storehouse,office building,civil dwelling,traffic tunnel,underground building,etc.

2.Equipments: power installations,communication facilities,underwater facilities,aviation instruments,cabins of warship or ship,water or oil pipelines,etc.
