Wondermask© P Peelable Temporary Solder Mask

Techspray Wondermask© P is a temporary, peelable solder mask or resist composed 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 and will not stain substrates. Material stability problems, common in natural latex formulations, are avoided. When applied, the product appears opaque pink, and when cured, becomes completely translucent red. Cured mask can be used in water or solvent systems and in masking for conformal coatings. Excellent heat stability allows for prolonged exposure to high temperature without product degradation. This product may be used in most common forms of mask applications such as robotic, pneumatic, hand applied, or template screening (not recommended for silk screening).
