HumiSeal Introduces UV92 a UV-Curable Thixotropic Masking Gel

For Immediate Release

HumiSeal® is proud to introduce the new UV92 – a one part, thixotropic, UV curable masking gel for temporary protection of components during the coating process.   UV92 is user-friendly during application, curing, and removal process.   This product comes in various cartridge sizes and bulk packaging directly from HumiSeal and authorized channel partners.

Application of HumiSeal UV92 is simple due to its high shear thinning property, which allows the gel to reduce viscosity during dispensing. UV92 ease of dispensing and accuracy of placement by properly wetting the surface makes it ideal for protection of critical components. The material will return to its gel state when not sheared. The UV92 masking gel cures with industry standard UV LED lighting at 365nm or 405nm, and has excellent solvent resistance once cured.

In its cured state, the UV92 will have a cloudy white appearance for easy identification without the need of black light and is easily distinguishable from conformal coating. The UV92 can withstand short temperature excursions up to 150oC for various conformal coating cure methods.

Removal of UV92 is simple, as it will peel cleanly with minimal exertion and no residues. UV92 will not stain metallic surface finishes such as gold, copper, silver, tin.

Features Benefits
High solids / 0 VOC Environmental health and safety advantage
Milky white appearance Easily distinguished without the use of UV black light during application and after cure
Ease of application Easily applied by robotic, table top, or hand-held dispenser
Thixotropic with high shear thinning Conforms to the desired shape on PCB and extremely easy to apply especially in tight spaces
Fast UV Cure Reduced WIP via a short process cycle time
Will not interact with conformal coatings Will not peel freshly applied conformal coating from the surface of PCB
Able to withstand 150oC for short period of time Capable of various conformal coating curing methods
Easily peel-able Fast process after conformal coating application to remove mask
No Residue Leaves clean surface after removal
No tarnish on metal finished No oxidation or discoloration of metallic surface such as Sn, Ag, Au, Cu

Keith Waryold (Vice President of Industrial Materials and Technology) said “Focusing on our customer requests, we continuously provide new solutions to the market. UV92 is another example of an environmentally friendly material that has been long requested by our customers. It is an exciting addition to further complement our conformal coatings product portfolio. The technology team at HumiSeal continues to make large strides in product development and we expect to be introducing more offerings in the near future.”

HumiSeal® Announces Revolutionary Masking Materials for Conformal Coating Applications

HumiSeal®, a leading conformal coating manufacturer has announced the global launch of its entirely new range of masking products.  Available globally in a wide range of sizes, the product is available in tape or dot format and addresses many of the common issues normally associated with effective and reliable masking.

The semi-transparent masking tapes and dots are made from a polyester film coated with a silicone free adhesive designed for fast and accurate application. A high surface conformability ensures there is no leakage under the tape the advanced adhesive ensures that it easy to remove leaving no residue and a clean, sharp edge between the coated and the masked area.   Extensive evaluations have ensured that the new range of products meets PCB manufacturing needs.   The latest materials are also silicone free to avoid de-wetting around masked areas.

The specific benefits the new HumiSeal range of masking products include:

  • High surface conformabilitymasking-application-dots
  • Clean, easy removal
  • Clean, accurate separation line
  • Silicone free adhesive
  • Easy peel-off dots from carrier tape
  • Solvent resistant
  • Semi-transparency for accurate placement verification.

The new materials are available globally directly from HumiSeal or from our channel partners. Standard sizes specific board designs are available. For available sizes and custom design information go to: http://www.humiseal.com/products/masking-products/masking-tapes/

Commenting on this new generation of masking materials Keith Waryold, Global Business Unit Director for HumiSeal, said:

“I am delighted that these products are now available to the industry. We have been developing the product range for some time, listening to customers, and trying to accommodate their requirements. These new dots and tapes represent an entirely new generation of masking materials, offering very good resistance to solvents while remaining silicone free”.
