Guide to Proper Surface Preparation for Plastic Bonding
Surface preparation plays a critical role in ensuring that good bond strength is achieved. While bonding plastic substrates effectively can be especially challenging, our guide outlines typical techniques for properly preparing plastic surfaces to yield optimal bond strength. This guide includes methods for degreasing, mechanical abrasion and chemical treatments.
Developed for priming and bonding polyolefinic substrates, Master Bond X21Med is a single component elastomeric compound that passes ISO 10993-5 tests for cytotoxicity.
UV17Med is a one part, UV curable adhesive formulated to provide excellent adhesion to many TPUs (thermoplastic polyurethanes) - widely recognized as challenging substrates for bonding.
EP29LPSP epoxy is a NASA low outgassing approved two part epoxy offering cryogenic serviceability. This low viscosity, optically clear system bonds well to a variety of plastic substrates.
EP42HT-2Med two part epoxy is widely used in medical devices due to its resistance to repeated sterilizations and its compliance with the testing requirements of USP Class VI plastics.
