What does texanol do in paint?
Eastman Texanol™ ester alcohol provides the highest level of film integrity at low levels of coalescent, enhancing the performance properties of the paint including low temperature coalescence, touch-up, scrub resistance, washability, color development, thermal flexibility, and resistance to mudcracking.
What is a coalescing aid?
A coalescing aid is often referred to as a temporary plasticizer for a film-forming polymer. The function of the coalescent is to soften the polymer during the crucial period of fusion so that the individual particles will combine to form a continuous film.
What is a coalescing agent?
Coalescing agents are used as an additive to reduce the minimum film formation temperature, resulting in optimized film coherence and improve film properties such as scrub resistance, abrasion resistance, mechanical properties, and appearance.
What does it mean coalescence?
to grow together
coalesce \koh-uh-LESS\ verb. 1 : to grow together. 2 a : to unite into a whole : fuse. b : to unite for a common end : join forces. 3 : to arise from the combination of distinct elements.
What is Mfft?
Minimum Film Forming Temperature ( MFFT ) is the lowest temperature at which a latex, emulsion or adhesive will uniformly coalesce when laid on a substrate as a thin film. An accurate MFFT value allows the formulation of products that cure correctly under specified application conditions.
How does a coalescing agent work?
Coalescing agents function as temporary plasticizers for the polymer particle and thereby reduce the MFFT. Coalescing agents allow the formation of polymeric films at ambient resp. temperature conditions of film application, even of polymers demonstrating a MFFT of above these temperature conditions.
What is coalescing in operating system?
In computer science, coalescing is a part of memory management in which two adjacent free blocks of computer memory are merged. When a program no longer requires certain blocks of memory, these blocks of memory can be freed.
How do you stop coalescence from emulsion?
Emulsions also contain emulsifiers – materials that concentrate at the phase interface to lower the interfacial tension. Emulsifiers reduce the energy required to break the dispersed phase into droplets and prevent them from coalescing by generating a repulsive force or a physical barrier between them.
