Product Description
Description
EP3108 series Clear epoxy potting adhesive is a room temperature/heat curing epoxy resin adhesive. This two-component epoxy adhesive is designed for potting, protecting electronic products that require high strength or confidentiality.
The EP3108 series of epoxy potting adhesives cure without heat. After thoroughly mixing component A and component B by weight ratio, the product cures within a certain time to form protection.
Typical Applications
Suitable for hard light strip, display module, photoelectric sensor, smart water meter and other photoelectric display devices and products
Key Features
This product is a transparent color epoxy potting material
Resistant to moisture, dirt and other atmospheric components
High strength, excellent adhesion, cracking resistance, toughness
With secret acting, no solvent, no curing byproducts
Stable mechanical and electrical properties at -45-90℃
Packing Specification
*
EP 3108 transparent epoxy Potting adhesive, order code: A: 2KEP6110; B: 2KEP6111
Component A: 10kg/ pot
Component B: 5kg/ pot
Transport &Storage
● When stored at or below25°C in the original unopened containers, this product has a usable life of 12 months from the date of production. Sampling test is necessary for products which exceed shelf life before taking use. During storage may have little settlement stratification, stirring evenly when use, does not affect performance. It’s non-dangerous goods, can be transported as normal chemicals, CAUTION leakage during transport.
Operation process Operation Matters
* Component A needs to be stirred evenly in the original package before use (precipitation may occur after a long time, and the performance will not be affected after the use of stirring evenly). * Affected by temperature, there are certain differences in the curing speed of glue in different seasons, and the curing time is longer in winter. All of the above glues can be heated to accelerate curing. You can also choose to use MAXTECH winter formula.
* The A and B components of some products may crystallize and caking under low temperature conditions, which is a normal phenomenon; Before use, put it in the oven at 80℃ to melt it, and put it to room temperature for normal use, without affecting the properties of the glue. * During the mixing process, pay attention to the glue on the inner wall of the container and stir it back to ensure the uniformity of mixing.
Use the process
* Gluing: Stir the glue component A fully in the original package, take the A and B components according to the specified mass ratio (see the table above), mix and stir well, and then potting and sealing. The operating time after mixing is shown in the table above. After the operating time is exceeded, the glue will become sticky and no longer suitable for pouring. Therefore,the amount of glue should not be too much each time to avoid waste. * Curing: curing conditions refer to the table above. The curing speed of glue is related to temperature, and the higher the temperature, the shorter the curing time. In winter, the temperature is low, the curing time will be extended, can be heated curing method, heating for 2 hours under the condition of 80℃. The glue can be assembled after curing and hardening. It is recommended to proceed to the next step after curing for 24 hours.
Q:How long can I get a quote A:The quotation can be provided no longer than 24hours on condition that we know all detailed requirement.
Q:Do you accept private Label? A:Yes. ODM & OEM are Welcome.
Q:Can I get a samle before order? A: Of course. Generally, we provide 1-3 pieces free samples for quality testing and the courier fee be born by customers. Thanks for your understanding.
Q:Do you have MOQ. A:Yes, Generally ,MOQ is 1000pcs or 1000kg.
Q: How long will finished my order? A: It’s depend on your order quantity. Generally, Our production time is 10-15 days after get the payment.
Q:How to find the suitable sealant? A: Please let me know your application purpose,substrate, application method and all your requirements. We would like give you a better recommendation.
As our suggestions of the sealant choose: 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.
