TechSpray, 2211-G, WonderMASK™ P Peelable Solder Mask, Pink - 1 Gallon
TechSpray, 2211-G, WonderMASK™ P Peelable Solder Mask, Pink - 1 Gallon
Techspray 2211-G WonderMASK P is a one-gallon format of the manufacturer's peelable temporary solder mask. The non-ammoniated synthetic acrylic latex formulation supports temporary protection during qualified PCB assembly and conformal-coating masking operations. Select this format when your consumption and approved dispensing process call for a larger container.
Best Uses / Applications
- Temporary masking of through-holes and specified component areas in wave-soldering workflows.
- Protecting contacts and other keep-outs from compatible liquid conformal coatings.
- Template, hand, pneumatic or robotic application using suitable equipment and a qualified procedure.
- Higher-consumption operations evaluating one-gallon supply rather than smaller bottles.
- Temporary component tacking where the assembly process permits it.

Key Features and Process Guidance
Techspray describes WonderMASK P as low odor, non-ammoniated, nonflammable, easily peelable, and compatible with gold and copper leads. The color darkens during cure. The manufacturer identifies it for fluxing, wave soldering and cleaning operations as well as conformal-coating masking, subject to the applicable instructions and process qualification.
Use a substrate free from flux, oil and particles. Apply the specified thickness and follow current cure instructions. Do not overcure: blistering can create removal problems. For conformal coating, cure the mask first and establish a removal window that avoids coating damage and trapped mask. Follow the current SDS for the formulation and lot supplied.
The former listing grouped workplace exposure references as product standards. Those references are not being presented as a product certification or an assembly-compliance guarantee.
One Gallon vs. 8oz vs. Washable Mask
| Option | Selection consideration |
|---|---|
| 2211-G | One gallon for larger consumption and approved dispensing workflows |
| 2211-8SQ | Smaller 8oz bottle in the same WonderMASK P family |
| Water-washable temporary mask | Different formulation and removal method; do not substitute without qualification |
Frequently Asked Questions
Is this a peelable or washable mask?
WonderMASK P is peelable. Its removal method differs from Techspray's water-soluble mask families.
Can I use it with conformal coating?
Techspray identifies WonderMASK P for conformal-coating masking. Confirm compatibility with the exact coating, solvents, exposure, geometry and removal sequence.
What thickness does Techspray recommend?
The published P guidance specifies 20–30 mil. Apply current supplier instructions and qualify the result on the actual assembly.
What are the published cure options?
One hour ambient, 30 minutes at 65°C, or 20 minutes at 82°C. Conditions affect drying. Do not treat these values as approval for every assembly or overcure the mask.
When should it be removed after coating?
Techspray's general guidance recommends peeling after the coating is dry to the touch but before full cure. Establish the correct window for the specific system.
Why are two viscosity ranges shown?
The manufacturer's TDS and selection guide give different typical ranges. Confirm the current applicable product specification rather than assuming either range is a guaranteed lot limit.
