APPLICATIONS
鈥? Use the product as a coalescing aid in Latex paint formulations
This product lowers the minimum film formation temperature = MFFT
The product softens the emulsion polymer particles, allowing them to fuse together to a proper film at lower
temperatures than is otherwise possible
PERFORMANCE BENEFITS
鈥? The level of addition is easily adapted to a wide range of emulsion polymers and paint applications
Use more product with harder emulsion polymers to achieve the same MFFT as with softer ones
Use more product to achieve the lower MFFT needed in demanding outdoor applications
