VERTELLUS Biothane® SYSTEM 337 two-component polyurethane adhesive suitable for packaging of hemodialyzers

Products Description

Biothane™ 337 is a bio-based two-component polyurethane adhesive system, Suitable for the packaging of hemodialyzers. Compared with other similar products, this system can provide a better balance between process latitude and production efficiency, and a more suitable hardness increase. The resulting wide cutting window can cover different production rhythms , Better process adaptability makes it very convenient to adjust the process parameters. The system also has excellent bonding performance.

Operation Recommendation

1. Please read the product safety manual (MSDS) before using this material, and Evaluate and follow the recommended actions

2. Both Vorite 2050 M-1 and Polycin 2566 are sensitive to water vapor and should be kept The packaging should be sealed to prevent water vapor from intruding during the use of the material. Vorite 2050 M-1 can react with water or water vapor, making the product turbid or crusted and then ineffective. Polycin 2566 that is left open or poorly sealed can slowly absorb moisture in the air and make the final product The product produces foam.

3. Vorite 2050 M-1 must be stored indoors at 21-35°C .Below this temperature may lead to crystallization of the product. Short-term crystallization can be achieved by putting the slightly closed packaging drum into an 80-degree oven for no more than 8 hours to melt the crystals and shake the drum fully after cooling .
