MAX ACR A/B is an epoxy-based resin system formulated as an aquarium-safe coating, casting, fiberglassing and bonding resin. It cures to a transparent clear and a durable chemical resistant polymer that demonstrates excellent stability in both fresh and saltwater immersion.

MAX ACR A/B is mixed 2:1 and cures at room temperature. It is low in viscosity and provides 35 to 50 minutes depending on the batch size and ambient temperature. MAX ACR works well as a barrier coating for wood. Upon full cure, MAX ACR is waterproof and will prevent leaching of chemical compounds harmful to aquatic animals. It bonds to cement or concrete ponds providing a hermetic sealant that is resistant to chipping or delamination. It also bonds to glass, wood, PVC and polypropylene plastics, making it a strong adhesive.

MAX ACR A/B is also used as fiberglass impregnating resin for fabricating large plywood custom aquariums. It bonds well to tempered glass, acrylic plastics, wood, and ceramic products. To ensure good adhesion, clean the substrate thoroughly, and remove any surface contamination and organic residue.

Measure the mix ratio accurately (2:1 by weight or by volume) and mix well to prevent leaching when in contact with the aquarium water. Cure the MAX ACR application for 2 to 3 days and then rinse with tap water before use.
