Kester 53-4003-0533 is a 1 gallon container of TC-533, White Peelable Solder Mask.
Kester TC-533 is a high-temperature flexible solder masking compound specially formulated of natural latex rubber. The latex has been chemically enhanced so that it is heat stable and tacky enough to be applied to those areas of circuit boards, which require masking during a wave soldering process. Kester TC-533 effectively masks and protects the board from the time it is manufactured, through all assembly and flow operations. Kester TC-533 can remain on the protected areas of the board until ready for test, and then, with only a mild pulling action by hand or tweezer-like tools, can be easily peeled away without leaving a residue. Kester TC-533 prevents solder from flowing into contacts, terminals, screw heads and plated through holes.
Will not tarnish gold or phosphor bronze
Protects delicate components
Please note: Use of TC-533 is not recommended on bare copper as it contains ammonia which will cause discoloration of the copper.
Viscosity (typical): 11,500 cps
Brookfield viscometer @ 20rpm and 25 degrees C
Parts to be protected must be free from oil, grease and silicones to ensure proper adhesion. Kester TC-533 can be thinned with water and uncured mask left on equipment can be removed with water. A 15-mil thick coat of Kester TC-533 will cure approximately 45 minutes at room temperature or 15 to 20 minutes at 66 degrees C (150 degrees F). Warming the surfaces prior to application will expedite cure. High relative humidity or greater coating thickness will necessitate longer cure times. Kester TC-533 may be exposed to oven temperatures of 82 degrees C (180 degrees F) and lower for up to 16 hours without degradation. At temperatures of 82-120 degrees C (180-250 degrees F) exposure time should be limited to two hours, at 120-149 degrees C (250-300 degrees F), 30 minutes. Exceeding these exposure times will cause Kester TC-533 to soften and lose elasticity. Exposure of TC-533 to oven temperatures above 129 degrees C (300 degrees F) is not recommended.
