TECHNISAND TRUCOAT® LE
Low emission resin-coated sand
Dramatically cut emissions:
TECHNISAND TRUCOAT LE resin-coated sand is the core-and-mold casting system that dramatically lowers odor, in-plant smoke, and other emissions while delivering superior performance.
Advanced resin-coated technology:
- Lowers hazardous air pollutants (HAPs) by more than 41%
- Reduces free formaldehyde by 35%
- Decreases free phenol levels 62% without sacrificing product integrity.
Benefits:
- Reduce odor and in-plant smoke
- Lower VOCs and HAPs
- Decrease overall environmental footprint
This innovative foundry solution reduces scrap. Best core-surface density and uniform curing provide near-net shape casting to decrease cost.
TECHNISAND TRUCOAT®
High-performance resin-coated sand
Increase productivity:
Regardless of the metal casting you are producing, TECHNISAND TRUCOAT resin-coated sand outperforms any traditional resin-coated product. This is the right solution to increase productivity and casting quality with less sand while not compromising the commitment to cleaner air.
Benefits:
- Improve flowability
- Produce complex cores at a very low core weight
- Minimize scrap cost
TECHNISAND TRUCOAT® AL
Aluminum casting resin-coated sand
Significantly improve core shakeout:
TECHNISAND TRUCOAT AL resin-coated sand is the high-performance solution to significantly improve core shakeout in non-ferrous applications. Now, customers can eliminate use of the heat-treat oven to remove cores from castings and eliminate post-bake core downtime. This important product is available in GFN 30 to 100 AFS in your choice of sand. Coarser grades are also available to improve permeability and reduce or eliminate gas defects.
Benefits:
- Produce high strength cores with excellent shakeout
- Improve productivity
- Reduce casting scrap
- Reduce energy cost
