IsoBond 41

IsoBond 41 is a one part; single coat bonding system. IsoBond 41 is suitable for bonding castable polyurethane elastomers and RIM polyurethanes to a variety of substrates; including mild steel; stainless steel; brass; aluminum; acrylic plastics; ABS; GRP; epoxies; and concrete at ambient temperatures of 68° F (20° C) or above. The system has been designed to bond polyurethane elastomers curing at temperatures from 68–194° F (20–90° C). However; higher temperature curing elastomers; also bond well with IsoBond 41. When used as a two component adhesive with IsoCure B; improved environmental resistance is achieved and the system will bond fusion bonded epoxies and cured elastomers such as NR; CR; PU; etc.
