I did some testing for them recently on their new formulations. The 51 cure is just about the same as West System 105 resin and they have both a slow and fast hardener. I really couldn't tell any difference and I've used West system for years. The cost here in Canada is significantly lower than West. There is also a 31 cure coming in the near future. By the way the 51 refers to the mix ratio. The new 31 formulation is primaraly a coating resin with properties similar to West 105 with the 207 hardener.
Industrial Formulators was started here in British Columbia and was bought by System Three about a year or so ago. I used IF resins in the manufacturing company I owned and always was satisfied with their products.
