Crestabond® PP-04 Structural Adhesive
Our Crestabond PP-04 is a new, innovative 1:1 structural adhesive within our Crestabond range. This adhesive is specifically designed for use on low surface energy substrates such as polypropylene (PP), polyethylene (PE), and other thermoplastic polyolefins (TPOs) that are typically difficult to bond. With excellent adhesion abilities and high strength, it replaces the need for mechanical fasteners or plastic welding, allowing for greater design flexibility.
The PP-04 adhesive has a working time of just 3-5 minutes, but a fixture time of 165-180 minutes at 23°C and 80-100 minutes at 50°C. Despite their non-porous and chemically inert surfaces, this adhesive will easily bond to thermoplastics without the need for pre-treatment or primer and is suitable for gap filling between 0.5 and 5mm.
Crestabond PP-04 is supplied in 50ml and 400ml side by side cartridges. These should be kept at all times within a temperature-controlled environment between 5°C and 8°C to stop the adhesive thickening and becoming unusable.
