Tenax Fixtop Epoxy Setting Adhesive A + B
Tenax Fixtop Epoxy Adhesive is a true 100% two-part epoxy glue...not water based. It is very easy to mix and spread. Suitable for gluing and bonding marble, granite, stones, mosaics, porcelain and ceramics as well as hardwood, cement board, laminate and plywood. Works best when applied in a thin layer. Use to bond metal to stones, concrete to metal, ceramic to stone, stone to honeycomb panels. Does not dissolve or break down in water so it is great for shower applications and won't delaminate. No issues with expansion or contraction. For indoor and outdoor use.

Instructions
Make sure surface to be treated is completely dry and clean. Keep the glue and hardeners in their original cans. If using an automatic dosing pump avoid contact with metals made of copper, brass or similar metals which may rust. Avoid use of PVC plastic. Use only plastic that is corrosive resistant. Measure out, in either weight or volume, the correct amounts of part A and part B. Mix well using clean tools. Best when applied in a thin layer. Use acetone or butyl acetate to clean tools.
Shelf Life
Keep the containers closed after use. Keep away from heat, humidity and sun light. This product will last 2 years under normal conditions between 65°s and 77°.
Applications
