EP 3090 High Performance Electronic Epoxy structure adhesive

EP 3090 epoxy adhesive is a two-component room temperature curing epoxy resin. Designed for bonding ceramic, metal, glass, plastic, rubber, paper, cloth and other materials.

A and B components are thoroughly mixed 1:1 (weight ratio or volume ratio) after use, the product has a 40 min operation time, after curing to form a transparent hard protective layer, and there is a black version.

The cured adhesive has the following characteristics:

Resistance to moisture, dirt, and other atmospheric components
High strength, excellent adhesion
Good pollution resistance, low surface pretreatment requirements
No solvent, no curing byproducts
Stable mechanical and electrical properties between -50 and 120℃
It has good adhesion to plastic PC, glass fiber cloth and steel plate

50ml and double-barrel support, the use of 1:1 mixing glue gun construction, the glue of the first extrusion of the mixing tube is discharged, in order to prevent the uneven initial mixing resulting in poor bonding effect. Double barrel packaging should pay attention to the sealing of the material port, and replace the mixing hose in time. Manual use of bulk packaging, mixing adhesive materials need to be quickly weighed and stirred, this method is suitable for places with low bonding requirements; Otherwise, you need to use a two-component dispensing machine to mix and apply glue. The temperature is too low will cause the curing speed to be slow, and when the initial strength cannot be reached, it needs to be controlled at the site by constant temperature. Care needs to be taken to keep the Cartridge mouth sealed during use of cartridge packaging.
Components A and B should be kept away from light and heat and sealed (can be transported and stored as non-dangerous goods);

Storage period Component A: 1 year, Component B: 1 year (25℃);

Beyond the validity period, if you need to continue to use, please first test whether it can be cured normally.
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.
