Recently, national meteorological center of CMA has released clod wave yellow warning signal: it is estimated that from 20th to 24th, a gale accompanied by a drop in temperature will successively happened from north to south in most areas of mid-eastern China, average temperature will drop by 6~10 degree centigrade. On the early morning of 24th, the lowest temperature of northern areas of North China Plain will drop by about 10 degree centigrade, the lowest zero temperature line will appear between middle reaches of the Yangtze River and Yangtze River-Huaihe River. With sudden drop in temperature, unit in charge of construction in most areas of Northern China are purchasing necessary grass cover, iodine-tungsten lamp, electric furnace and other heating and heat preservation materials. On this circumstance, which matters needing attention in the construction and preservation of epoxy structural adhesive?
Epoxy structural adhesive produced by Nanjing Mankate is majorly used to paste engineering structural components, carbon fiber sheet, metallic and so on, including carbon fiber adhesive, construction structural adhesive and underwater special adhesive and so on. Adhesive manufactured by Mankate abounds in great abration-resistance, endurance, corrosion-resistance, toughness and shock-resistance, underwater special adhesive can be used in humid environment, winning customers’ general approbation.
Structural adhesives produced by Nanjing Mankate mostly are epoxy resin structural adhesive, which is very susceptible to temperature. The minor change in temperature will change its curing time and characters accordingly. In low temperature it is natural and easy for epoxy resin adhesive to crystallize. Due to the character of adhesive, it will transform from liquidity to crystalline solid. The principle of crystallization of epoxy resin adhesive is similar to that of other materials. High purity, low viscosity, impurity, extreme environment and thermocycling will increase the possibility of crystallization. Due to epoxy resin adhesive’s sensibility to temperature, under extremely cold environment or big fluctuation in temperature, it will transform from liquidity to solidity very easily, which is also called the crystallization of epoxy resin adhesive.

Nanjing Mankate epoxy structural adhesive abounds in the advantage of long-term and stable use, no matter in alpine region or humid tropic areas, it can be used safely. You do not need to worry about the adhesive agglomeration in winter, you can heat the adhesive to soften it and then it can be used as usual. As for viscosity of structural adhesive and difficulties in construction, here are several solutions:
Mankate carbon fiber epoxy impregnating adhesive
1. Heating preservation can be applied, such as using iodine lamp, infrared lamp, electric furnace and water bath and so on to preheat adhesive to 20℃~40℃. If conditions permit, heating the pasting areas for 24 hours will gain a better effect.
2. Epoxy structural adhesive can be stored in greenhouse for maintaining its heat balance and then can be took out and be used in construction.
3. Keeping distance with epoxy structural adhesive as prerequisite, the heating method such as electric radiator can be adopted to consistently heat the adhesive till it recovers to its original status.
Nanjing Mankate has passed the ISO Quality System Standards and EU CE Certification. It is the brand broadcasted on CCTV, whose products safety is approved under national high requirements and covered Ping An Insurance Company of China. There are few industries owning the same testing equipment as national inspection center, which allow customers to inspect its tensile strength, elasticity modulus and elongation on the spot, and place orders after seeing its data! So come on and take a look! High quality and great service are always our pursuit!
