Description
MAX GPE A/B MEDIUM SET is mixed two parts Resin to one part Curing Agent by weight or by volume (2:1). The mixed consistency is very low in viscosity, clear and easily poured or applied in to place resulting in bubble free castings. MAX GPE A/B MEDIUM SET has a 60 minutes gel time that allows adequate working time for casting, coating, bonding and potting or encapsulating applications.
MAX GPE A/B MEDIUM SET performs well as an adhesive for metals, alloys, plastic, wood, stones products, fiberglass, carbon fiber composites and concrete and other substrates that require high tensile shear strength properties. Higher adhesion performance can be achieved after a post cure cycle of 1 hour at 120oC.
MAX GPE A/B MEDIUM SET coating properties exhibits very high gloss, good color stability, high surface and excellent chemical resistance.
Optimized amounts UV inhibitors, anti-oxidants and stabilizers are incorporated with the MAX GPE A/B MEDIUM SET to provide added outdoor durability.
An aliphatic polyurethane coating should be applied to further improved resistance to UV degradation.
MAX GPE A/B MEDIUM SET can be used as a protective or decorative coating for metals, alloys, plastic, wood, stones products, fiberglass, carbon fiber composites and concrete and other substrates
Higher coating performance can be achieved after a post cure cycle of 1 hour at 120oC.
MAX GPE A/B MEDIUM SET is an excellent choice for composite fabrication using fiberglass, carbon fiber, Aramid, and other hybrid fabrics. Its low viscosity allows fast fabric wet-out resulting in minimal void and laminant porosity. Cured composites fabricated with
MAX GPE A/B MEDIUM SET exhibits exceptional mechanical properties such as impact resistance, compressive and tensile strength. Higher mechanical performance can be achieved after a post cure cycle of 1 hour at 120oC.
As a casting resin and potting compound, MAX GPE A/B MEDIUM SET demonstrates good dimensional stability excellent electrical insulative performance and low coefficient of expansion and contraction.
General mechanical properties are enhanced after a post cure cycle of 1 hour at 120oC.
