Altek® H520-B

Altek® H520-B by AOC is a prepromoted, thixotropic, general purpose low reactive orthophthalic polyester resin. It provides good chemical bonding between laminate applications if proper application procedures are followed. Has low exotherm which is allowed for the application of thick laminate sections that can cure at one time without the generation of excessive heat. Altek® H520-B produces a composite with superior mechanical properties that can assist in the reduction of cracking when it is used with the proper glass reinforcement content.
