General Description
Polyolefin adhesive (SpiderAdhesive PP-332) is a two-part (10:1 ratio by volume) acrylic- based plastic bonder, with working time of between 4 to 6 minutes, and fixture time of about 90 minutes. It is effectively bonds polyolefin substrates (PP, PE, PVDF, PTFE...) with little to no surface preparation and no primers required.
The off-white mixed adhesive is resistant to most automotive and industrial solvents, including ethylene glycol, brake fluid, power steering fluid and iso-pentane. It will give assembly engineers an alternative bonding technology for joining low surface energy thermoplastics such as polypropylene or polyethylene.
More, It can be used to bond dissimilar plastic substrates (polypropylene, polyethylene, polycarbonate, and PMMA), metals (carbon steel, stainless steel and aluminum), or fiber-reinforced plastics with a minimum of surface preparation to reduce labor costs and production cycle times.
SpiderAdhesive Polyolefin adhesive provides an alternative bonding technology to mechanical assembly or solvent welding, and it can replace screws, rivets, plastic welding. In addition, it produces a bond with excellent resistance to water and humid environments.
