PU8018(2#) High Performance Two Component Silicone Gel

Product features and applications

PU 8018 is a two-component solvent free polyurethane gel at room temperature or heat curing, used for two component sealing and filling. The raw material does not contain heavy metals, green environmental protection, wide process operability, high physical properties of the finished product, and good adhesion to the substrate. Room temperature and heating can be cured, can be deeply cured, two components after mixing has a good fluidity, after curing hardness is very low, excellent flexibility, excellent low temperature resistance, used in communication equipment, transformers, control power, ignition controller, electronic sensors and other pouring and filling.

l Low viscosity, strong operability

l Excellent low temperature characteristics, excellent weather resistance

l Excellent electrical insulation and stability

l Good waterproof, moisture-proof, water absorption is very low

Material taking: Material A of this product contains functional resin. Pay attention to check whether the package is intact before material taking. After material taking is completed, seal the original package in time to prevent excessive contact with moisture. After the adhesive material is exposed to air for a long time, it may lead to bubbling phenomenon after AB material is mixed.
l Operation matters: Material B exposed to the atmosphere will absorb water and hydrolysis occurs, the phenomenon is cloudy until caked, material A also needs to be stored against the tide, so as not to generate too many bubbles during curing. The environment of the curing process needs to control the humidity as low as
Precautions

possible, and the relative humidity should not exceed 60%.
l Preheating: Please bake the poured device at 70~80℃ for 1~2 hours. The temperature can also be reduced to extend the heating time to remove the moisture of the device.
l Defoaming: Vacuum the A\B barrel respectively, and stir at the same time to ensure that the A\B glue is vacuum-free before mixing.
l Pouring: the mixture is poured into the device through the static mixer, and the gel time is about 360mins.
l Curing: 25 ℃ /24 hrs. Ambient humidity should be controlled at <70%, low temperature should extend the curing time as appropriate.

As a manufacturer, we would like to share with you what we have learned about the different types of potting compounds and their characteristics.
The potting compounds on the market vary in viscosity, requirements for cure conditions, among other factors. Compounds such as polyurethane, silicone, and epoxy are widely used in a variety of applications.
Silicone Potting Compounds are soft and flexible, silicone potting compounds and encapsulating materials possess a good level of elongation.Silicone potting compound can also withstand a wide range of temperatures. Most silicone materials are able to operate at temperatures between -40°C and 200°C.
Epoxy potting compounds generally perform as a better adhesive, high-temperature resistance, and chemical resistance and have better adhesion to a wide variety of substrates and typically do not need primers.
Polyurethane Potting Compounds generally have better flexibility, elongation, and abrasion resistance.
Acrylic Potting Compounds are UV and heat-hardening materials, with fast hardening, adequate chemical resistance, and clear appearance.
