Alphaset's unique water soluble phenolic chemistry can be used with all types of sand and provides foundries with high quality castings, less cleaning room costs, and increased profits.

Acid Cure

Enviroset® 3D Jet Resin

HA-International’s newest resin, Enviroset 3D Jet Resin, is a low viscosity thermosetting furan resin that has been specially manufactured for use in all 3D Printers for sand cores and molds and is suitable for use with all types of metal.

This furan resin offers a number of features and benefits that set it apart from conventional furan resins on the market:


  • Contains no nitrogen
  • Low water
  • Non-reportable formaldehyde and phenol
  • Low viscosity
  • High tensile strength


  • Increased productivity – resin helps print heads to last longer
  • Reduced labor – cores are cleaned faster
  • Reduced costs – resin is less expensive

Airkure / Super Set / Enviroset

Our wide product selection allows you to select the right product to meet your specific application. No matter what your particular goal is, we are certain that one of our acid cure No-Bake resin systems will get the job done.

HAI's acid cure resins range from high FA content, low water, zero nitrogen to Furan modified resins that offer the lowest cost, while maintining the expected performace in the mold making process without compromising casting quality.

Aikure along with Enviroset, and Super Set resins provide a diverse selection of products for various casting types. With nearly every combination of furfuryl alcohol, water, urea and plasticizer chemistry, HAI can accommodate any casting application.

Enviroset 138 PNB

Enviroset 138 is an alternative to Furan Based resins that has sufficient hot strengths and tensiles but with a lower cost compared to Furan resins.

HAI's Enviroset 138 is used in conjunction with the same catalysts used with our Furan line of products.

This resin also exemplifies some of the fastest curing speeds for a Furan free, resole based resin, allowing for a great alternative for current Furan foundries.
