Basic Information

Unistole™ is a primer and adhesive of which the main component is a modified polyolefin in a liquid state.
The modified polyolefin is obtained by introducing functional groups onto a base polyolefin using Mitsui Chemicals’ polymer modification technology.

These polyolefinic primers and adhesives can be used for coating and bonding polypropylene (PP) and various engineering plastics, rubber and other materials, which do not readily bond and as adhesives to bond metals to polyolefins in automotive, packaging and paint applications.

UNISTOLE™

CHARACTERISTICS

Flexible at low temperatures

Versatile one-pack primer can improve coating application efficiency because it dries at normal temperatures allowing “ wet-on-wet ” coating.

Excellent secondary adhesion

Remains flexible at low temperatures. Coated articles exhibit excellent flex resistance and impact resistance.

APPLICATIONS

Primer for coating and adhesives, food packaging, easy-peel packages, PTP packages, automobile parts, gravure coaters, roll coaters, sprays

CHARACTERISTICS

UNISTOLE™ P, A

Liquid primer for coating and bonding polypropylene (PP) and various engineering plastics, rubber and other materials, which do not readily bond.

UNISTOLE™ R

Modified polyolefin dispersed in hydrocarbon-based solvent used as an adhesive for bonding metals to polyolefins. Can also be used as a metal coating agent.

UNISTOLE™ XP, H

Varnish with non-chloric acidified polyolefin resin.
Can bind polar resins such as polyester and non-polar ones such as poly-olefin, can also be used as primer for painting on polyolefin resins that are usually hard to paint on.

UNISTOLE™ P, A Liquid Primer Characteristics
  • An easily handled one-pack primer that dries at normal temperatures so “ wet-on-wet ” coating is possible.
  • Appropriate for coating and bonding almost all paints and adhesives and all types of PP.
  • Suitable as a primer for coating and bonding engineering plastics such as nylon, polyester resin and FRP, rubbers such as EPDM, metals and other materials that do not readily bond.
  • Possesses excellent secondary adhesion and excellent gasoline resistance.
  • A UNISTOLE™ P coated film is flexible even at low temperatures, and articles coated with it exhibit excellent flex resistance and impact resistance.
UNISTOLE™ R Characteristics
  • Excellent adhesion to various metals.
  • Exceptional heat resistance and heat resistant adhesion.
  • Superb resistance to retort treatment.
  • Useable with simple equipment such as gravure coaters, roll coaters and sprays.
UNISTOLE™ XP, H Characteristics
  • Excellent adhesion to various substrates: polyolefin, metals, polyester and etc.
  • Excellent chemical resistance.
  • Useable with simple equipment such as gravure coaters, roll coaters and sprays.
