APPLICATIONS:

Casting and Molding:
Polyurethane and silicone resins for producing flexible and rigid parts including gaskets, seals, rollers, wheels, gears, prototypes, and industrial molds.


Adhesives and Sealants:
Epoxy, polyurethane, and acrylic resins for structural bonding, assembly adhesives, construction sealants, and automotive/aerospace applications requiring chemical resistance and mechanical strength.


Coatings:
Epoxy, polyester, alkyd, and polyurethane resin systems for protective coatings, industrial equipment finishing, marine coatings, and corrosion-resistant layers.


Composites:
Epoxy, polyester, and vinyl ester resins for fiber-reinforced composites (fiberglass, carbon fiber) in marine, automotive, aerospace, wind energy, and infrastructure applications.


Electrical Encapsulation:
Polyurethane and epoxy potting compounds for protecting electronic components, LED assemblies, sensors, transformers, and circuit boards from moisture, chemicals, and mechanical stress.


Construction Materials:
Polyurethane and epoxy resins for flooring systems, sealants, waterproofing membranes, and insulation applications requiring durability and weather resistance.

​

Automotive Parts:
Polyurethane cast resins for bumpers, interior trim components, seating foam backing, NVH (noise/vibration/harshness) dampening, and suspension bushings.


Elastomers:
Polyurethane and silicone systems for manufacturing flexible components including gaskets, seals, molded rubber parts, and impact-resistant materials.

Benefits:

Mechanical Properties:
Resin selection influences hardness (Shore A/D), tensile strength, elongation, flexural modulus, and impact resistance based on polymer type, crosslink density, and filler content.


Chemical Resistance:
Epoxy and vinyl ester resins provide resistance to acids, bases, solvents, and oils when formulated appropriately. Performance depends on resin chemistry, cure conditions, and exposure environment.


Processing Flexibility:
Available in liquid (castable, sprayable), solid (molding compounds), and UV-cure formulations to accommodate casting, molding, laminating, potting, and coating processes.


Cure Profile Options:
Room-temperature cure, heat-activated cure, and UV-cure systems available. Pot life ranges from minutes to hours depending on formulation and catalyst/hardener selection.


Substrate Adhesion:
Adhesion performance depends on surface preparation, primer use, and resin chemistry. Compatible with metals, plastics, wood, concrete, and composite substrates when bonding conditions are controlled.
