High Temperature Masking
Our high temperature masking solutions are expertly designed to protect components during finishing processes such as powder coating, painting, and anodising. Manufactured from advanced materials, these products ensure reliable performance and easy removal, even after exposure to elevated temperatures and harsh chemicals.
DO YOU KNOW
Masking Failures Can Destroy A Full Coating Run?
Poor masking is the top cause of coating failure
Correct Masking for Proper Grounding
Over-masking reduces coating adhesion; precise masking preserves grounding.
Thread Protection During Finishing
High-temp masking protects threads from contamination and preserves torque accuracy after finishing.
Masking for Extreme Heat
Silicone caps resist extreme heat and chemicals, ideal for powder coating and anodising lines.
Silicone Protection for Plating Lines
Silicone masking resists chemical baths, protecting surfaces that must stay uncoated.
High-Temp Materials for Clean Coating
Masking materials must withstand 200–315°C; weak plastics deform and contaminate coatings.
Residue-Free Masking Removal
Incorrect masking causes residue; silicone and poly plugs ensure clean, safe removal.
APPLICATIONS
Most coating failures start at poor masking—heat distortion can ruin sealing surfaces.
