6. Good waterproof, moisture resistance, low water absorption 
7. Flame retardant grade up to UL94 V-1 

Operation 
1. Mixing: Stirring A component evenly in the original package, then A, B components according to the Weight ratio of 7: 1 are weighed and mixed, then start to potting after mixing evenly. 
2. The B component may appear crystal or caking during storage ( this is normal), if the crystallization Need to placed in the oven at 80° C to melt before using(the containers should be in open state, in order to avoid the gas expansion, damage container), and Then cooling to room temperature before using, It does not affect its performance. 
3. If necessary, the device with good sealing can continue to vacuumize, is helpful to increase the Electrical properties of the device. 
4. The curing conditions: 80 ° C/2hrs or 25 ° C/24hrs. 
5. For the use of glue equipment please consult our marketing department. 

Package Storage 
A component: 14kg/ plastic bucket Keep in cool and ventilative place 
B component: 1kg/ bottle Temperature≤ 25° C, humidity≤ 50%RH 
Shelf life: 12 months both of A and B

Q:What are cots for?
Fluorine rubber rollerWith high heat resistance, oil resistance, acid and alkali resistance and other properties, air permeability, electrical insulation, aging resistance, flame resistance and wear resistance is also very good, for special coating equipment. Carbon fiber rollerLight quality, high strength, high temperature resistance. It is applied to special industries such as wide film and so on.
Q:Plastic material is rubber or oil?
It can be said that plastics and rubber are usually obtained from petroleum, and some of them are natural and made of rubber trees
Q:Are rubber materials isotropic? Or is it anisotropic?
Generally, it's the same sex, but it has something to do with the direction of your calender
Q:What kind of rubber is an edible grade safety rubber?
Natural latex sterilized as condoms, natural rubber or butyl glue used in oral liquid or infusion bottle glue plug, silica gel is most commonly used in the body false organs, mainly stable, no bacteria and so on.
Q:What are the insulation materials for wires and cables?
[low density polyethylene (LDPE), density (HDPE), high density (HDPE) and linear low density (LLDPE), polyvinyl chloride (PVC)], [crosslinked polyethylene material, peroxide crosslinking of silane crosslinked material, radiation crosslinking material] (XLPE), crosslinked polyvinyl chloride (XLPVC), low smoke halogen-free polyolefin (DWPJ), low smoke and low halogen polyolefin (DDPJ), polypropylene (PP), polytetrafluoroethylene (PTFE/F-4), fluorinated ethylene propylene (FEP/F-46), polyamide (PA6), polyimide (PI) etc.;
Q:Which material has the most slippery soles?
To sum up: rubber bottom and bottom Dichotomanthes toughness, better wear antiskid effect. If you want to buy anti-skid shoes, choose shoes should be knocked on the knock, the best flexibility, if only the lines are deep, and the soles of the material is very hard, then still not slip. Similarly, the density is not slippery tendon end.
Q:How to distinguish a basketball, what kind is all PU material, what kind is pu+ rubber material?
The PU-- cortex is soft, it is common for the basketball material, the price is not expensive, more suitable for frequent field cement, in the wooden floor or plastic ground with this estimate or dribble hand sweat like feel not so good.PVC-- polymer material, PVC, one of the most common plastic products, is widely used in wire, sheath and fiber skin. They are also made of gloves, sandals, slippers, soles and the like. This should be better than PU, but also more suitable for external field, aerobics.
Q:The difference between elastomeric and incompressible rubber
Elastic rubber: refers to the nature of a reversible deformation shows a kind of polymer material with natural rubber represented under external force. The elastic rubber is entropy elasticity, high elasticity is mainly internal entropy contribution within this contribution is zero.
Q:What are the categories of foamed rubber materials?
Rubber cotton: a sponge, the main ingredient is natural latex foam material, it has the characteristics of rubber, excellent elasticity, good elasticity, no deformation of recycled cotton: recycled cotton is from waste cotton, industrial waste and textile enterprises and the yarn head made of cloth recycling, waste cotton, especially in the raw materials may also contain medical use therefore, recycled cotton will cause harm to human health, cotton and cotton are common civil regeneration is likely to cause pollution.
Q:What's the difference between asphalt oil and rubber oil?
The modified asphalt is made from Wen Liqing in china. In ordinary medium temperature asphalt, benzene insoluble BI is about 18%, quinoline insoluble fraction, QI is about 6%. When the asphalt is treated with heat, hydrogen molecules, methane and water are produced by chemical reactions in the process of thermal shrinkage of aromatic molecules in asphalt. At the same time, some of the original beta resin in the asphalt is converted into two times of alpha resin, part of the benzene dissolved into beta resin, the alpha component is greatly increased, the cohesiveness is greatly increased, and the asphalt has been modified. This kind of bitumen is called modified bitumen.
