Structural Adhesives
Our range of high-performance ingredients provides durability opportunities and improved adhesion to a wide variety of substrates such as plastics, aluminum and composites used in structural adhesives applications. This allows manufacturers to currently replace materials with adhesives for long lasting benefits like:
- Low temperature flexibility and high temperature resistance; due to low Tg and high flexibility in combination with intrinsic resistance against heat aging
- Durability: a unique combination of thermo-oxidative and hydrolysis resistance
- Moisture repellency of the final adhesive, also achieved for PU dispersions
- Adhesion to a wide range of substrates, including low-polarity plastics
- Good chemical resistance
Adhesion to various substrates – Plastic & Steel
Moisture cured PU: high strength to hard, smooth and flexible plastics
Priplast™ amorphous (1838) and semi-crystalline (3192) grades bring high bonding strength.
Polyamide-6 Polystyrene
Lap shear adhesion; ISO 4587 | SF = substrate failure | NB = no break
We also offer 100% bio-based* alternatives: Priplast 3238 (amorphous) and a new Priplast 3294 (semi-crystalline).
Moisture cured PU: polar metal substrate but good adhesion
Priplast™ for good adhesion to dissimilar materials: various plastics or fiber-reinforced plastics as well as metal.
Lap shear adhesion; ISO 4587
High-Impact Strength for Epoxy Adhesive
Epoxy structural adhesives are well-known for offering excellent bonding strength, replace mechanical fastening and welding and high chemical and heat resistance. However, wouldn’t it be nice to have improved impact resistance maintain the hardness?
B-Tough™ A2 increases toughness and maintain hardness (Shore A 82-84-87).
Priplast™ 3192 is the most universal building block in the Priplast™ polyol range and is suitable for polyurethanes and polyurethane dispersions in coatings and adhesives.
This waxy polyol has a molecular weight of 2000. The product is ideal for flexible substrates like leather and textile and for rigid substrates like metal, plastics and wood (where it enhances the grain appeal). Priplast™ 3192 offers excellent hydrolytic resistance and mechanical properties.
Priplast™ 3192 is an ISCC PLUS certified product. The vegetable oil-based content comes from sustainable ISCC certified sources (mass balance), supporting the sourcing of vegetable oil.

B-Tough™ A2
Our epoxy functional toughening technology brings impact strength to structural resins and adhesives without impacting the hardness of the matrix.
These products enhance durability by absorbing microcracks caused by ageing and thermal shock. B-Tough™ A2 is a reactive toughening ingredient that brings excellent stability and is recommended for use in liquid and/or solid type epoxy resins (medium polarity grade).
Priplast™ 3196
Extreme hydrophobicity and excellent durability for PU sealants and elastomers is offered with Priplast™ 3196. This waxy, amorphous polyester polyol (MW 3000) has good hydrocarbon compatibility for polymer blends and has possible uses in flexible applications such as leather coatings.
Priplast™ 3196 is an ISCC PLUS certified product. The vegetable oil-based content comes from sustainable ISCC certified sources (mass balance), supporting the sourcing of vegetable oil.
