Product description

MDEP 3005 Two-component epoxy structural adhesive is a room temperature fast curing epoxy resin adhesive. This two-component epoxy adhesive is designed to bond ceramic, metal, glass, plastic, rubber, paper, cloth and other products.

The MDEP 3005 quick-setting epoxy adhesive cures without heat. After thoroughly mixing component A and Component B at 1:1 (weight or volume ratio), the product cures in 10-30 minutes to form protection.

How to use

Precautions for operation

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.
This glue curing process is an exothermic reaction, and the amount of glue will affect the length of operation time, so the operation time under the amount of glue 2g is only a reference time.
