  • New glass-to-metal seal is close to perfect
    with Minneapolis, solves quality problems stemming from thermal-expansion mismatches in older methods. These problem manifested themselves as compromises between seal reliability and image quality. The seal also better protects optical equipment from contamination such as hydrocarbons and moisture, thereby...
  • HumiSeal(R) 1B66 (.pdf)
    A fast air drying, single component, acrylic coating that provides excellent moisture and environmental protection for printed circuit assemblies. The final film demonstrates excellent flexibility and is easily repairable. HumiSeal 1B66 is in full compliance with the RoHS Directive (Directive...
  • Rapid parts for the long haul
    and moisture resistance are key properties needed to test the hair dryer in its working environment where hot, humid conditions are anticipated. Additionally, the resin's low coefficient of thermal expansion helps ensure the resin keeps a tight grip on the dryer's metal grill at elevated temperatures during...
  • HumiSeal(R) 1B31S (.pdf)
    1B31S is a modified version of 1B31 with improved adhesion to solder masks. 1B31S is a fast air drying, single component, acrylic coating providing excellent moisture and environmental protection for printed circuit assemblies. The final film demonstrates excellent flexibility and is easily...
  • HumiSeal(R) 1B31 (.pdf)
    A fast air drying, single component, acrylic coating that provides excellent moisture and environmental protection for printed circuit assemblies. The final film demonstrates excellent flexibility and is easily repairable. This coating is MILI- 46058C and IPC-CC-830 qualified. Fluoresces under UV...
  • Picking A Winning Nylon For The Roller Derby
    to flat development even under varying environmental conditions, such as changes in temperature, humidity, and UV exposure, means that despite the long period of downtime during the off season, roller performance is not affected when the lift is put into service in the winter. With moisture...
  • Picking A Winning Nylon For The Roller Derby
    in the winter. With moisture absorption, tensile strength of nylon 6 can drop to below 20%, while for cast nylon 12 it remains stable within 90% of its original value. Moisture absorption causes swelling which results in up to 3.3% dimensional change in the nylon 6 family. When designing with nylon 6 or 6/6...
  • Unfilled Liquid Crystal Polymers
    Unfilled (neat) liquid crystal polymers (LCP) have excellent thermal and dimensional stability, as. well as high rigidity, strength, and chemical resistance. LCP parts can be molded with great. precision, are flame retardant, absorb little moisture, are highly impermeable to gases, withstand...
  • AN0005 Mechanical Cracking
    . Excessive bending will create mechanical crack(s) within the ceramic capacitor. Mechanical cracks, depending upon severity, may not cause capacitor failure during the final assembly test. Over time moisture penetration into the crack can cause a reduction in insulation resistance and eventual...
  • AN0001 Polymer Termination
    . Excessive bending will create mechanical crack(s) within the ceramic capacitor. Mechanical cracks, depending upon severity, may not cause capacitor failure during the final assembly test. Over time moisture penetration into the crack can cause a reduction in insulation resistance and eventual...
