J301 PU Based Adhesive,
ISO9001 PU Based Adhesive,
J301 2 Part PU Adhesive
J301 Polyurethane Adhesive For Automobile Manufacturing Industry
J301 is a two-component adhesive. Component A is composed of a variety of polyols, adhesion enhancers and fillers, and the appearance is light yellow red viscous fluid. Component B is composed of coarse MDI, which is brownish yellow transparent viscous liquid.
The PU adhesive is mainly used for bonding honeycomb board and corrugated board products. After bonding, honeycomb board can be sprayed through the production line, and can also be used for composite bonding for decoration of all kinds of metals, wood, porcelain chips, polished bricks, stones and so on.

3. PU Adhesive has several advantages:
• Good flexibility
• High bonding strength
• Water and heat resistant
• BEECORE Polyurethane composite adhesives are widely used in the construction industry, automobile manufacturing and shipbuilding, such as polyurethane sandwich panels, aluminum honeycomb panels, polystyrene foam panels, fiberglass panels, stone composite panels, metal plates, etc.
5. Quality control:
A very technical engineering team. The general manager has worked in the Netherlands. The core technologies are introduced from the Netherlands. Others are very young and have more than 5 years of practical experience.
Strict QC team: 8 people are responsible for PU Adhesive of quality control of parts, processing, testing, packaging, etc.

7. Company profile
1958 Besin brought honeycomb technology into China, and Besin (Suzhou) company was established.
s are widely used for railway industry, Shanghai Expo, marine furniture etc.
lant-porous aluminum honeycomb core, PU adhesive, as well as honeycomb filters.
9. Matters needing attention:
1. The amount of glue should not be too much to avoid accelerating curing and shortening the application period due to exothermic reaction.
2. There shall be absolutely no water during bonding. Grinding the bonded surface can increase the bonding strength, while epoxy primer on the bonded metal surface can increase the bonding.
The surface to be bonded and coated after pretreatment shall be dry and free of grease, dust or other dirt. If the metal surface is coated with primer or the plastic surface has discharge agent, it shall be removed; The bonded surface is polished. In some special cases, epoxy primer or anodic oxidation may be used, and the adhesion will increase significantly.
For construction and bonding J301, take an appropriate amount of glue solution according to the mass ratio a: B = 5:1, stir and mix evenly (based on the uniform mixing of the colors of glue solution a and b), and then coat, scrape and trowel the evenly stirred colloid on the required plate with a scraper, with the glue application amount of 0.35-0.5kg per square meter.
After mixing, J301 can be mixed evenly at room temperature for about 50 ~ 60 minutes, and the initial curing time at 25 ℃ is about 6 ~ 7 hours. If the temperature is low, the curing time needs to be prolonged. It can also be cured quickly by heating. Generally, it can be basically cured after 1 hour at 60 ℃.
The uncured glue can be cleaned with special cleaning agent, such as acetone. The cured glue can only be removed by mechanical method.
Afraid of freezing: Yes
Storage temperature: at room temperature (recommendation: about 25 ℃), when the storage temperature is too high, the reaction speed is fast and the operation time is short after taking and mixing; The temperature is too low, the viscosity is thickened, and the glue mixing and scraping are laborious.
Validity: 12 months after the original packaging
Barrel packing: 25kg (group A), 5kg (group B) can be packed according to the specific requirements of customers
