Usage method
Instructions for use

● Before use, it is necessary to ensure that the indoor humidity is below 70% RH. Do not open the packaging before this.

● Before mixing, component A must be stirred evenly, and then proportioned according to the A: B=100:20 mass ratio. When mixing, attention must be paid not to

● Excessive air intake is recommended. It is recommended to use an automatic mixing device to accurately mix resin and curing agent in the correct proportion without introducing air.

● If not used, the containers for components A and B must be kept sealed at all times to prevent inhalation of moisture.

● After long-term storage, the filler in the adhesive will settle. Please mix evenly before use. Insufficient mixing can lead to unstable or incomplete resin performance.

● To reduce the viscosity of the mixture and facilitate subsequent sealing, component A can be heated to 50 ℃ before mixing. If the mixture is deaerated under a vacuum degree of 5-10mbar and then sealed for use, better mechanical and electrical properties can be achieved.

● Baking temperature: Bake at 60 ± 5 ℃ for at least 1 hour.


matters needing attention

● Before use, please refer to the MSDS in detail. Store away from children.

● It is recommended to use it in a well ventilated area.

● Avoid direct contact when using, and protective equipment such as gloves should be used. If it accidentally sticks to the skin, it must be immediately cleaned with soap and water. If it accidentally sticks to the eyes, it is necessary to first wash with a large amount of water and go to the hospital for examination.

● For industrial use only, please refer to MSDS for details.
