Product Description

High Performance Optically Transparent Optically clear Waterproof Polyurethane Potting for Electronics

Description

PUR 1660A/B is a two-component-free-free room temperature or a heat-curable polyurethane gel for two-component sealing and filling. The raw material does not contain heavy metals, green environmental protection, wide process, high finished physical properties, and good binding properties. The room temperature and heating curing can be deeply cured, and the two groups have a good fluidity after mixing, the hardness is extremely low, the flexibility is excellent, and the low temperature resistance is excellent. It is used in communication equipment,transformers, control power, ignition Pouring and potting of controllers, electronic sensors, medical insoles etc.

Typical Applications

It is used in communication equipment,transformers, control power, ignition Pouring and potting of controllers, electronic
sensors, medical insoles etc.

Optical grade transparent polyurethane potting is a liquid resin used to encapsulate electronic components, particularly LEDs, for protection and aesthetic appeal.

Optical grade transparent polyurethane potting is a liquid resin used to encapsulate electronic components, particularly LEDs, for
protection and aesthetic appeal. These compounds are formulated to be optically clear, meaning they do not yellow from UV exposure, and provide protection from environmental factors like moisture, dust, chemicals, and physical impact. They are available in two-part systems that can be poured or cast to protect and stabilize electronic assemblies.

Key Features

* Low viscosity, strong operability *Low hardness and certain toughness *Excellent electrical insulation, stability * Good waterproof, moistureproof, very low water absorption * Good adhesion to most metals and plastics

* High transparency: Formulated to remain crystal clear and prevent yellowing from UV light exposure, making it suitable for applications where visibility is crucial.
* Environmental protection: Shields electronic devices from dust, moisture, chemicals, vibration, and impact.
* Mechanical stability: Enhances the mechanical stability and dielectric strength of electronic parts.
* Versatile application: Can be used for both protective and decorative purposes, such as potting and encapsulating LEDs, electronic devices, or for doming labels and badges.
* Easy processing: Often available in a simple 1:1 mix ratio with low viscosity, which aids in application and allows for excellent penetration and air release.

Packing Specification

PUU1660 A/B polyurethane potting compound Order Code: A: 2KPU2072; B: 2KPU2073 A: 18kg/ iron drum or 200kg/ iron drum B:
18kg/ drum or 200kg/ drum Other colors need to be customized Other packaging needs to be customized This glue is not dangerous and can be transported as a general chemical .

Transport &Storage

● Unused raw materials should be stored in a well-sealed bucket to avoid moisture intrusion and affect the quality of raw materials. The opened materials should be kept sealed and used up as soon as possible. ●It is recommended to store in a cool area, away from direct sunlight; ?Storage temperature: 10-30℃, A material storage period of 12 months; Material B is 6 months..

How to use a) Use: The raw material of material A contains functional resin, before taking the material, pay attention to the detection package is intact. After the filler is completed, it is sealed to prevent the original packaging to prevent excess of moisture. After the rubber is exposed to the air time, it may cause the AB material to bubbling the phenomenon. If conditions permit, the original packaging of material A can be placed in an insulated environment above 30 degrees. b) Operation: B material is exposed to water absorption in the atmosphere, and the phenomenon is turbid until agglomeration, and the A material also needs to be stored, so as not to solidify excessive bubbles. The environment in which the curing process needs to control the humidity as low as possible, and the relative humidity should not exceed 60%. c) Preheat: The cast device is taken from 70 to 80 ° C for 1 to 2 hours. It can also reduce the temperature to extend the heating time to remove the device moisture. At low temperatures The viscosity will increase. The material can be preheated to 25℃ to 45℃ for easier use. d) Defoulating: Vacher for A B buckets, simultaneously, to ensure that the A B glue is vacuum- free. e) Pouring: Put the mixture into the device through a static mixer, the gel time is approximately within 60 mins. f) Curing: 25℃ / 24 hrs. The environmental humidity should be controlled at <70%, and the temperature is low to 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. 1. 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. 2. 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. 3. Polyurethane Potting
Compounds generally have better flexibility, elongation, and abrasion resistance. 4. Acrylic Potting Compounds are UV and
heat-hardening materials, with fast hardening, adequate chemical resistance, and clear appearance.
