Room Temperature Curing Polymer Systems

Room Temperature Curing Polymer SystemsRoom or ambient temperature curing systems offer easy processing and high reliability. These one and two component systems are used in bonding, sealing, coating and potting/encapsulation applications.

Types of Room Temperature Curing Compounds

Master Bond room temperature curing adhesives are presently employed in various industries ranging from aerospace, optical, electronic, oil/chemical processing, medical and automotive. Our product line includes:

  • One and two component epoxies
  • One and two part silicones
  • Cyanoacrylates
  • Elastomeric contact cements
  • UV curable systems (cure upon exposure to UV light)

Rapid Room Temperature Setting Epoxies Have Unique Properties

Master Bond epoxy systems EP51M and EP30-4 have set up times within 4-8 minutes at ambient temperatures. Their rate of cure will depend on bondline thickness, humidity, temperature and the types of substrates they are joining. Cryogenically serviceable EP51M exhibits superior tensile shear strength and a Shore D hardness >70. Master Bond EP30-4 is a low viscosity, optically clear, non-yellowing compound with outstanding electrical insulation properties. It has a compressive strength >10,000 psi.

Most Popular Room Temperature Curing Adhesives, Sealants, Coatings, Potting and Encapsulation Compounds
