USAGE GUIDE FOR RAPID-SET EPOXY ADHESIVE (118-AF) FOR TRAFFIC MARKERS

A new rapid-set, two component epoxy adhesive for bonding traffic markers to roadway surfaces is described and guidance for its purchase and use is presented. This adhesive is designed for machine mixing and dispensing and has the following principal features: (1) Polymercaptan cure, which imparts rapid-set at low temperatures, (2) Fibrillated polyethylene as the thixotrope, i.e. non-asbestos, (3) Low viscosity which allows good mixing even at moderately low temperatures. The rapid cure should allow sufficient set of the adhesive and the development of sufficient adhesion that traffic can be allowed to contact the markers in less than 15 minutes after being placed at temperatures of 72-82 F (22-28 C). This guide is designed to furnish users and purchasers detailed information in the following areas: (1) Background on the development of the adhesive, (2) Details regarding the composition of the adhesive, (3) Specific data on properties and experience in the field, including comparisons with the California Rapid-Set Epoxy Adhesive, (4) Guidance regarding its use in the field and precautions regarding handling, and (5) Information regarding raw materials costs. A proposed specification is presented.
