9912 - 100 Percent Soilds Epoxy Mastic
100% Solids Epoxy Mastic -
100% solids two part epoxy system for bonding and filling concrete and other substrate. Rhino 9912 offers long work life, quick cure, good chemical resistance and low odor during application. Rhino 9912 is a syntactic, light weight mastic with excellent thixotropy, it trowels easily on vertical and overhead surfaces. Easy to use 2:1 volume mixing and color coding ensure a proper mix every time. DOT and IATA non-corrosive for ease of transportation.
Rhino 9912 is intended primarily as an adhesive for bonding similar and dissimilar substrates. Due to its moisture tolerance and chemical resistance, this system finds wide application in concrete repair. On properly prepared concrete, the material tolerates hydrostatic pressure(s) typically found in concrete sewer and wastewater applications.

Liquid Properties of Rhino 9912
|Weight per Gallon, Component "A":||7.7 lbs%|
|Weight per Gallon, Component "B":||6.5 lbs|
Directions For Use
Thoroughly mix parts “A” and “B” until a consistent gray color is achieved. Properly prepare concrete substrate prior to bonding. No standing water may be present when material is applied. Apply mixed material by trowel or putty knife to desired thickness. Allow approximately 8 hours at 77°F to allow “green” strength to develop. Full properties develop in 7 days at typical ambient temperatures.
