Common 852 epoxy balance clay
Ⅰ.Description
852-2 epoxy balance clay is non-toxic,room temperature curing,curing speed is moderate;
The product after curing has high hardness, good chemical resistance, good insulation sealing, good flexibility, etc. properties.
Recommend the encapsulation used in products, such as last 30000 r/min electrical machinery rotor , motor or winding coil, etc.;
Also be used in jack-up electrical machinery , automobile electrical machinery , little electrical machinery , direct current machine ,etc.
Ⅱ. Operation method
Dust and oil on the surface should be cleaned by using cloth rubbing or organic solvents;
Mix method: Repeat most simple and most convenient way “strand -twist-fold";
Mixture ratio: A: B =100: 100 (by weight)
According to the mixture ratio by weigh, weigh it precisely and make a thoroughly mixing in order to prevent curing from being incomplete, and then used out in service time
The more glue amount mixed together is, the faster its response is, and quicker the speed of curing. Please pay attention to controlling quantity which mix the glue, and used in short-time.
Before using in a large amount, please try out in a small amount first, grasped the using skill of the products.
Using gasoline, etc. hydrocarbon solvents can clean non-cured glue.
