Technical Data Sheet ALPHA/BETA MAX RECLAIMED SAND ADDITIVE ABM-602 ALPHA/BETA MAX 602 (patent applied for) is a liquid/solid additive used with the ALpHASET Systems and the BETASET Process to increase rebonding strengths on reclaimed sands obtained from the ALpHASET/BETASET cores or molds. ABM-602 will allow the consistent use of high addition rates of reclaimed sand. ABM-602 helps the ALpHASET System or BETASET Process to rebond reclaimed sands. The performance value increases as the level of reclaimed sand mixed with new sand increases. Operational levels are from approximately 60% to 90% reclaimed sand. Reclaimed Sand Successful reclamation of ALpHASET or BETASET bonded sands is possible with existing reclamation processes. Dry attrition, pneumatic scrubbing or thermal units, either individually or in combination, can provide adequate treatment to allow for consistently high levels of sand reuse. Control of the reclamation process must be monitored by testing the reclaimed sand. Screen analysis, LOI and tensile strength tests should be used to monitor the reclaimed sand system. New Sand Addition New sand should be added to the system in a manner to maintain a constant reclaimed/new sand blend. ABM-602 Use Levels ABM-602 is typically used at 0.2% t o 0.6% on the weight of the sand. The determining factors are: 1. 2. 3. 4. Quality of reclaimed sand Reclaimed levels used Rebond strengths desired Quality of the sand mixers Each foundry may require different levels, determined after the foundry is reclaiming ALpHASET or BETASET and has accomplished several cycles of reclamation.

Mixer Addition of the ALpHA/BETA MAX There are several techniques for the addition of ABM-602 into continuous mixers. The techniques are detailed in order of preference. 1. Precoating the Sand: Introduce the material to the sand stream prior to resin/hardener sequence. For closed tube, high-speed mixers, air assist may be necessary to insure good mixing. 2. Twin Screw Mixers: We recommended that the ALpHA/BETA MAX is introduced to both sides of the mixer prior to the addition of the ALpHASET and ALpHACURE components or the BETASET resin. 3. Muller or Batch Mixers: The preferential technique is to add the ALpHA/BETA MAX first and employ a short mixing time, followed by resin. Pumps and Hoses ALpHA/BETA MAX 602 is an aqueous suspension; therefore most existing pumping systems currently approved for foundry use can be utilized. It is recommended that the pump is sufficient in accuracy to insure adequate metering of the material. Storage and Handling ALpHA/BETA MAX 602 is non flammable. The product should be handled properly utilizing approved chemical safety equipment. The product is supplied in open head steel drums. Consult the product Material Safety Data Sheet for specific information as well as the Technical Data Sheet for information. Avoid freezing conditions.

As such, its performance value increases as the level of reclaimed sand increases. In order to optimize its use, it should be added at approximately 0.6% on sand weight while maximizing the amount of reclaimed sand used. Once the highest level of reclaimed sand is achieved, a programmed reduction in the additive amount should be undertaken until the minimum tensile for any particular operation. In summation, maximize the reclaimed sand level first, and then minimize the additive level to achieve desired rebond strengths while keeping the resin/hardener levels constant. NOTE: It is important to premix the ALpHA/BETA MAX 602 prior to use and during use. Without mixing, settling of the solids will occur. Thermal Reclamation ALpHA/BETA MAX 602 has been successfully tested in most thermal reclamation units resulting in excellent rebonding strengths. It is recommended to add the ALpHA/BETA MAX 602 prior to the sand entering the reclamation unit starting at 0.6% B.O.S. The use of ALpHA/BETA MAX 602 is non-hazardous and non-corrosive making it very user/equipment friendly. There are no acids or alkalies in the product. It is important to work with HA International’s technical department when considering thermal reclamation in order to maximize the benefits.
