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.

- Hard polyurethane coating agent polyether based polyurethane foam density: 0.04 ~ 0.06g/cm3 hard polyurethane foam density: 0.03 ~ 85 0.07g/cm3 polyurethane density of about 1.2g/cm3, no filler generally around 1.1
- Q: What kind of material is the bottom of flip flops? Foam or rubber?
- Compared the two are from Brazil, but both the work is completely different. Havana is the finished cut, according to account Ipanema is a rubber injection molding. But because of technological reasons, Ipanema more colors, fashion elements more than Havana. Suggestions can be considered ipanema.
- Q: How to strengthen the adhesion between rubber and metal skeleton material
- The adhesion between reinforcing rubber and metal skeleton material was summarized from 4 aspects of rubber formulation system, rubber surface treatment, surface treatment of metal skeleton and selection of adhesive system.
- Q: What material is FPM?
- Fluorine rubber is a special synthetic elastomer, the main chain or side chain carbon atoms with a fluorine atom electronegativity strong, because the C-F bond energy (485KJ/mol), and the fluorine atom covalent radius is 0.64A, equivalent to half of the C-C bond length, so the fluorine atom can put the main chain of C-C well shield, ensure the stability of the C-C chain, which has excellent performance can not be compared with other rubber, such as oil resistance, oil resistance, chemical resistance, good mechanical properties and weathering resistance, electrical insulation and radiation resistance, in all its best performance in synthetic rubber, commonly known as "the king of rubber".
- Q: Rubber, nylon, chemical raw materials are divided into several categories?What kind of material is the automobile tyre?
- The skeleton material is the reinforcing material of the main force part of tire, carcass and buffer layer (band layer), and its performance has important influence on the mechanical properties and service life of the tire.
- Q: What are the non combustible materials?
- Gypsum board, gypsum board, fiber cement board, mineral wool acoustic board, glass wool sound-absorbing board, perlite sound-absorbing panel, flame retardant plywood, flame retardant MDF, mineral wool decorative board, burning wood, aluminum foil composite materials, flame retardant plywood, aluminum foil phenolic FRP composite materials etc.
- Q: The difference between elastomeric and incompressible rubber
