Rev. A (04/18) Page 1 of 2 WonderMASK P Peelable Solder Mask Product 2211 Product Description WonderMASK P is a temporary, peel-able solder mask comprised of a thixotropic, synthetic acrylic latex designed to withstand fluxing, wave soldering and cleaning operations. Unlike natural latex mask, it contains no offensive ammonia and hence is non-corrosive to copper, gold, silver or pre-soldered surfaces. In addition, stability problems are averted. When applied, the product is opaque pink, and when cured, becomes completely translucent red. Cured mask can be for masking conformal coatings. May be used in applications such as robotic, pneumatic, hand applied or template screening (not recommended for silk screening). Techsprays WonderMASK is the industry-leading temporary solder mask brand because of quality and versatility. Depending on the product, mask can be peeled off manually or washed off in a batch or inline system. WonderMASK has a number of useful applications in PCB assembly: Typical Product Data and Physical Properties Thru-hole masking Prevent soldering open holes in a wave Physical state: Liquid soldering process by covering with WonderMASK. All of the masks Color: Pink/red listed below are well suited for this application. Relative density: 1 Conformal coating masking In a conformal coating dipping or Shelf life: 2 years spraying process, WonderMASK can be used to cover connectors and other components and areas that should not be coated. Temporary component adhesive WonderMASK can be used to Performance & Application Data tack down components on double-sided PCBs. Application Template, hand, pneumatic, robotic All Techspray WonderMASK products have the following advantages: Viscosity 28,000-30,000 cps Can be cured in pre-heat Suggested thickness 20-30 mils Withstands lead-free soldering temperatures up to 640F (343C) Thinner DI water in wave soldering process Cure time 1hr. Ambient, 30 min. 65C, RoHS compliant 20 min. 82C Removal Peel-able Features / Benefits Non-ammoniated Nonflammable Easily peel-able Low odor Cure indicator - darkens as it cures Compatible with gold and copper leads Usage Instructions Apply a 20 to 30 mil coating for best results to desired area. The substrate should be free from flux, oil, and particulate matter. Drying times depend upon ambient humidity. Under normal conditions WonderMASK P is ready for preheating stage in 1 hour, however, cure can be accelerated to 30 minutes at 65C/150F or 20 minutes at 82C/180F. Do not over cure, as blistering of mask can occur, causing removal problems. Mask will change from an opaque pink to a translucent red when complete cure is accomplished. Mask does not have to be completely dry to withstand soldering operation however, it should be completely translucent before removal. 800-858-4043 www.techspray.com Rev.
