Resin Systems
HA International provides a complete range of organic or inorganic resin systems for all metal types, processes, and environmental considerations to meet all of your foundry needs.

Phenolic Urethane Cold Box (PUCB)
Foundries interested in productivity, using Phenolic Urethane Cold Box resins, appreciate the diversity of performance capabilities offered within the Sigma Cure product line. HAI’s Phenolic Urethane Cold Box resins are the best in the business when it comes to high core strengths, long mixed sand bench life, humidity resistance, and release characteristics that can’t be matched. If you haven’t tested one of the Sigma Cure products, you haven’t unlocked the productivity potential of your Cold Box operation. Click here to view our Sigma Cure product offerings.

The PUCB process utilizes an amine gas to catalyze the reaction between a phenolic resin and an isocyanate resin to produce a urethane bond. HAI's amine catalyst product line, Sigma Cat, is designed for use with our entire line of phenolic urethane cold box resins.

Phenolic Urethane No Bake (PUNB)
HAI’s Phenolic Urethane No Bake systems offer the same performance chemistry featured in the Cold Box resins but modified for No Bake applications. HAI's leading No Bake product line, Techniset is a commonly used No Bake system in the industry based on its value and recognized performance. HAI's Techniset offers a diverse product line, including low VOC systems using proven Biodiesel technology. In addition to general purpose resins we offer specialty systems for aluminum and non-ferrous applications. Click here to view our Techniset product offerings.

Warm Box System
The Warm Box System is a latest development in heat cured core making technology which provides improved core quality, high tensile strengths, long bench life, and reduced cycle times along with lower cure temperatures. HAI’s leading Warm Box Resin, Envirotherm, is a high tensile strength resin with improved humidity resistance, designed for use in a broad variety of casting applications.

Shell Resins
HAI produces the most complete line of liquid and solid phenolic shell resins in the foundry industry. The same quality of resin used to produce Custom Sands, Super Sands, Shake Free and Sigma Sands at our Oregon plant is available to foundries which conduct their own sand coating operations. Contact us today and let one of our experienced employees help you find the right resin to meet your foundry needs.

North American Foundry Resin Tote Recycling Program
At HA International we are committed to providing information to our customers regarding environmentally responsible handling of our products and containers. HA International offers our customers an environmentally conscientious alternative for Resin Tote disposal. Please view our Resin Tote Recycling Program for more information. This Tote Recycling Program only applies to Resins.

EcoMission Product Line
HA International supports sustainability by minimizing foundry environmental impact of our products while continually improving their performance and value. Our resin products Biocure, Cordis, Bioset, ALpHASET, Geopol, BETASET and Furan No Bake are part of the Environmental Solution.

Click here to view HAI's amine catalyst product line, Sigma Cat, designed for use with our entire line of phenolic urethane cold box resins.


Constant rising demands on quality and environmental compatibility confront foundries and their suppliers with an ever increasing array of new challenges. In addition to increasing productivity, meeting environmental and industrial safety regulations is part of our EcoMission strategy. With Cordis, its inorganic binder system liberates no smoke or odor during the casting operation. Click here to learn more about the Cordis Inorganic Binder System.


HAI's newest urethane No Bake system, Bioset, offers the same performance characteristics of our leading Techniset product line. This environmentally advantageous binder system is modified to contain very low free formaldehyde content and is coupled with a specially designed solvent package for lower odor and smoke during pouring, cooling and shakeout. Bioset Part 1 and Part 2 resins are environmentally friendly, high performance binder systems with patented chemistry to provide the highest hot strength available for these types of binder systems.

The first name in phenolic ester cured No Bake systems, HAI continues to improve this patented chemistry to achieve optimum productivity and casting quality. ALpHASET’s unique water soluble phenolic chemistry is capable of producing the highest level of casting quality, and minimizes the potential for casting defects experienced with other No Bake systems. The ALpHASET No Bake system is applicable to all types of metals being cast and excels in the production of large steel and alloy steel castings where other No Bake systems have shortcomings.

Unique Geopolymer modified No Bake silicate binder used for ferrous and non-ferrous casting applications. This resin provides better bonding strengths at lower application levels with higher sand flow ability. Casting finish and shakeout surpass traditional silicate binder systems. Geopol is more than just another sodium silicate! Click here to learn more about the Geopol system.


The same breakthrough chemistry which produced the ALpHASET system, was subsequently developed to produce the BETASET Cold Box system. The BETASET system uses a vaporized methyl formate gas to achieve a fast Cold Box cure and can be applied to a highly automated environment, such as automotive component production.
