PVA equipment can be used for a diverse array of applications from dispensing Adhesives and Sealants to Conformal Coating of PCB’s to dispensing Potting materials, be they single or multiple part. PVA can also supply curing solutions for all the above so a full turnkey solution is available with full process support.


The PVA Delta 6 is a new Selective Coating/Dispensing system.

With a flexible robotic system it is ideal for selective coating, potting, bead and meter-mix dispensing applications. The Delta 6 features a robust overhead three axis motion platform for in-line or batch production.

The Delta 6 has been designed with a slimmer footprint and improved structural rigidity which enhances positional accuracy and machine stability. Some features of the Delta 6:

  • Robotic system repeatability of 25 microns
  • Patented servo-controlled optional four-axis motion with valve tilt and rotate
  • Closed loop process control throughout the gantry system
  • Multiple dispensing applications or materials in one cell
  • On-board PC for unlimited program storage
  • Easy to use programming environment

The PVA350 is a Bench-top Selective Coating/Dispensing System


It is a flexible three or four axis robot that is suitable for virtually any bench-top or laboratory selective coating and automated dispensing application.

  • Compact, tabletop design that is portable
  • Large work area
  • Optional four-axis tilt and rotate motion
  • Co-ordinated motion in all axes simultaneously
  • Easy to use programming environment

PVA has many different valves available and has one to suit all any application from HotMelt Jet dispense to Film Coating to Metering valves and of course mixing valves, Any application with any material can be handled. Please contact us for further information.


 HumiSeal is a division of Chase Corporation and produces conformal coatings from all chemistries, including acrylics, urethanes and silicones, both water based and UV curable. This represents the largest product range and the widest choice of qualified products available. HumiSeal are always at the forefront of conformal coating innovation and product development. This means that HumiSeal can meet all your requirements while constantly striving to stay one step ahead as your business develops.


Acrylic conformal coatings are perhaps the most popular of all conformal coating materials as they are easy to apply and remove, with a wide  process window for use. Acrylic coatings dry rapidly, are fungus  resistant and provide long pot life. Additionally, acrylic materials  produce little or no heat during the curing process, eliminating  potential damage to heat sensitive components. The coatings possess low  shrinkage, provide significant humidity resistance and exhibit low glass transition temperatures.


Polyurethane coatings are available in either single or two-component  formulations. Both options provide excellent humidity resistance and far greater chemical resistance than acrylic coatings. Single component  polyurethanes, while easy-to-apply and enjoy long pot life, sometimes  require long curing regiments to achieve a full or optimum cure. In some instances, the cure cycle can be accelerated with the application of  heat.


HumiSeals UV curable conformal coatings represent an exciting  innovation that provides superior performance. When combined with  extremely fast curing, allows for short cycle times and maximum  production speeds. These products can be sprayed using traditional  automated spray equipment with the relatively simple addition of a  small-footprint UV light curing unit.


HumiSeals Synthetic Rubber products are unique formulations that may  enable the user to achieve specific protection / environmental goals not offered by “traditional” coatings. Synthetic Rubber materials are  characterized by extremely low glass transition temperatures, resulting  in stable modulus over a wide temperature range and extreme flexibility. Synthetic Rubbers have the least moisture permeability of all resins  currently available. These products do not necessarily represent our  complete Synthetic Rubber range.


Water-based conformal coatings, by their very nature, are extremely safe, low odor, low VOC products, developed to enable customers to meet  the ever-stricter emissions targets, not to mention the various health  and safety requirements. It enables enormous reductions in VOC emissions, especially in the automotive sector. These  products are based upon the standard chemistries of Acrylic, and Polyurethane, offering the closest match in protective performance to the existing solvent-based conformal coating range.
