Can anyone tell me what ingredient is in this product ?

Has anyone used this product before and can anyone tell me what the ingredients are,? I want to make sure it is safe for my acrylic plexi-glass tank.

Don't recall the product...I'd try it on an old piece of acryllic or something...let it dry and see what the results are...is it a background?
