Elastic adhesive | Designed for polypropylene (PP) materialsSX-PPK1000(EXP)

Features

  1. Designed for polypropylene (PP) materials
    Excellent adhesion to polypropylene resin, which is normally adhesive-resistant.

  2. One-part type
    Does not require primer application ,improving the work environment and increasing work efficiency.

  3. Adhesive for bonding different types of materials
    Excellent adhesion to polypropylene resin and various other materials. This is an elastic adhesive which can ease thermal stress caused by a difference in thermal expansion coefficient among different types of materials.

  4. Flexible Cured properties
    Designed for cured film properties that are excellent in flexibility and followings, and has excellent peel adhesion.

Application

  • For bonding polypropylene resin with different types of materials.
    (Not suited for bonding materials such as polyethylene, fluorine, and polyacetal)
  • For bonding that requires durability (e.g. in relation to thermal cycles).
  • For bonding that requires waterproof performance.
  • For bonding related to PP automotive parts, and electrical components and parts.
