Recommended Ratio (Wt%)

Remark:Users need to adjust the amount of “blue water” (Nap-Co or Iso-Co accelerator) and “white water” (MEKP curing agent) and their ratio for the right gel time according to the actual temperature. Different cobalt content of the accelerator and the effective oxygen content of the curing agent have the different curing effects, users must take the actual small test to confirm the amount of “blue and white water”. If high humidity or low temperature, the curing system by adding an appropriate amount of DMA (dimethylaniline), or the curing system by using BPO (benzoyl peroxide)&DMA are the better choice. Such as heat release of resin, gel time, “blue and white water” has special demands, please no hesitate to contact Tianhe Co.

Resin corrosion resistance
 As the corrosive mediums are too much, the detailed anti-corrosive guide data are not provided, if necessary, please contact us to demand anti-corrosion data sheet to determine how the selection or take on-site etching method with help of us.

Package&Storage and Safety Information

Package:200kg or 18kg clean and dry iron drum;

Safety suggestion:Accelerator and curing agent must be separated during the storage and transportation;

Skin and eyes should be avoided to contact with resin, and necessary protective equipment and clothing should be

worn, prohibit strictly pour into the water. For details, please see the MSDS.

Storage&Transportation: Drums-store at temperatures below 25°C/77°F, Storage life decreases with increasing storage temperature, Keep away from flames, fire and sparks, and no smoking, avoid exposure to heat sources such as direct sunlight or steam pipes, Store separately from oxidizing materials, peroxides and metal salts,Keep container closed tightly when not in use, don’t store outdoors, and avoid contamination of product with water. Should be refrigerated truck transport from May to October, at least at night, any inappropriate storage and transportation will lead to reduced resin shelf life; remove the drum top to replace the air and agitate in a period of time can extended the resin shelf life.

Particular remark:this technical data sheet and any information are our company 2008 version,they may be adjusted as technology development, we reserves the interpretation and amendment right without any Advance notice.
