MG Chemicals RTV615-1P Clear RTV Silicone, 1P Kit
MG Chemicals RTV615-1P — Clear RTV Silicone Potting Compound, 1P Kit
MG Chemicals RTV615-1P is a two-part, addition-cure clear RTV silicone potting and encapsulation compound offering optical clarity, excellent flexibility, and primerless adhesion to metals and most plastics. It cures at room temperature or with heat acceleration, producing a soft, flexible elastomer ideal for PCB potting, optical encapsulation, and LED applications where transparency is required.

Frequently Asked Questions
What is the mix ratio for MG Chemicals RTV615?
RTV615 uses a 10:1 mix ratio by weight (Part A to Part B). Accurate measurement is critical for proper cure — off-ratio mixing can result in incomplete cure or a tacky surface. Always weigh components rather than estimating by volume.
Is MG Chemicals RTV615 truly optically clear?
Yes. RTV615 cures to an optically clear elastomer, making it suitable for LED encapsulation, optical sensor potting, and display applications where light transmission is required.
Does RTV615 require a primer for adhesion?
No. RTV615 offers primerless adhesion to metals and most plastics. For difficult substrates, surface cleaning and light abrasion improve bond strength. Consult the MG Chemicals RTV615 datasheet for substrate-specific adhesion data.
Can RTV615 be heat-cured to speed up the process?
Yes. RTV615 can be heat-cured at elevated temperatures to accelerate cure time significantly. Consult the MG Chemicals RTV615 technical datasheet for recommended heat cure schedules and temperatures.
What is the difference between the RTV615-1P kit and the 1-gallon pail kit?
Both contain the same RTV615 formulation. The 1P kit is a smaller quantity suited for lab, prototype, or low-volume potting. The 1-gallon pail kit is more economical for higher-volume production potting operations.
