Q.: What is your opinion of an epoxy curing compound which is said to seal, harden and dustproof? What are its advantages?
A.: We are not familiar with this kind of curing compound but epoxy coatings in general have a good record for holding in moisture and resisting wear. It is possible that this compound functions like a wear-resistant coating as well as a curing and sealing agent. Unless it has been significantly diluted (which would greatly affect its properties) it might be fairly expensive. It should be added that there are a tremendous number of kinds of formulations of epoxy compounds, making it difficult to predict how any particular epoxy will perform without knowing more about it.
