Rockdefoam SLT-660
Rockdefoam SLT-660 is an emulsified silicone developed for atmospheric dyeing and finishing. Due to its scientifically balanced emulsification system, Rockdefoam SLT-660 is stable to prolonged boiling and will not break down causing spotting and build up on goods and equipment. Rockdefoam SLT-660 can be used as an antifoam and defoamer. Rockdefoam SLT-660 should be added prior to other chemicals that may generate foam. For the most economical usage due to its stability, additions during normal running procedures are not generally necessary. Rockdefoam SLT-660 is easily dispersible in water and water phase systems.

Application & Recommendation
Rockdefoam SLT-660 can be added directly to the foaming system or can be diluted with water prior to addition. Rockdefoam ST-660 is effective at very low concentrations. 10 to 50 ppm is a good starting point. The concentration can be increased or decreased to establish the most economical concentration. Rockdefoam ST-660 is stable in acid, alkaline or neutral system. Rockdefoam ST-660 is especially recommended for the following applications:
a)Textiles - dye becks, jigs, scouring operations, pad baths, and etc.
b)Latex systems - neutral or synthetic in either compounding or stripping operation.
c)Size mixes - starch, CMC, PVA and etc.
d)Paper coatings.
Rockdefoam SLT-660 is a very stable product, yet it releases its silicone very rapidly when added to the foaming media. As with most defoamers, best results are obtained by adding Rockdefoam SLT-660 to the system before foaming starts.
CAUTION
Rockdefoam SLT-660 is cold sensitive and in storage and transportation must be kept from freezing.
