HM-EP5921

Fast-curing epoxy AB sealant


Description

This product is composed of two components A and B. After mixing at a volume ratio of 1:1, it will react quickly for initial curing in 5 minutes at room temperature. It will reach 70% strength (210pa) in 1 hour and reach the best after 24 hours (25Mipa).


Typical Application

Plastic, single glass, marble, cement, sunken porcelain, wood and other rigid materials, suitable for bonding automobile interior parts, nameplates, bumpers, fuel tanks, water tanks and motorcycle windshields, as well as marble, cultural relics, electronic components and processes Jewelry bonding and repair, etc.

Not suitable for bonding elastic or soft materials.


Product performance characteristics

Fast curing speed, strong initial adhesion, good toughness, high strength. The cured product has good acid and water resistance, water and moisture resistance, oil and dust resistance, humidity and heat resistance and atmospheric aging resistance. At the same time, it has good electrical and physical properties such as insulation, pressure resistance, and high bonding strength. The curing speed can be adjusted, and slow curing (30min to 3h) has higher strength (≧30MPa) and is suitable for repairing cylinders, guide rails and impellers, and plugging trachoma.

Usage Guidelines

1. During the curing process, please clean used containers and utensils in time to prevent glue from solidifying on the product.

2. According to the proportion, after mixing agents A and B, they should be stirred thoroughly to avoid incomplete curing.

3. The parts to be bonded and sealed must be kept dry and clean.

4. After mixing evenly, please inject glue in time and use the mixed glue within the initial solidification time.

5. It will start to solidify after mixing, its viscosity will increase rapidly and it will release heat.


Storage method and shelf life

Store sealed in a cool, dry place away from light. The shelf life is 24 months.


Precautions

1. The product solidifies quickly, so please reduce the amount of glue at one time as much as possible! The more glue that is put together, the faster the reaction and the faster the curing speed, which may be accompanied by a lot of heat. Please pay attention to the amount of glue applied at one time, as the usable time will be shortened due to the faster reaction. Mixed glue should be used as soon as possible within a short period of time;

2. Prolonged contact with glue may cause slight skin irritation and slight itching. It is recommended to wear protective gloves when using to avoid direct contact with the skin. You can use medical alcohol to wipe and clean with detergent.

3. Before using a large amount, please try to use a small amount and master the skills of using the product to avoid making mistakes.
