What are coalescents?
1. To come or grow together into a single mass: the material that coalesced to form stars. 2. To come together as a recognizable whole or entity: the stories that coalesced as the history of the movement.
What is coalescent in paint?
Page Content. Eastman coalescents enable maximum film formation in latex paints, often improving overall paint performance. Coalescent works by softening the latex particles, allowing them to fuse into a tough, continuous film. Common coalescents include ester alcohols, esters, and glycol ethers.
What is texanol ester?
Eastman Texanol™ ester alcohol is the premier coalescent for latex paints. It performs well in all types of latex paints, in a variety of weather conditions, and over substrates with different levels of porosity. Eastman Texanol™; ester alcohol also enhances thickening efficiency when used with associative thickeners.
What is the use of texanol in paint?
Texanol 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.
Do people coalesce?
For example, a group of people could coalesce of their own accord, or a charismatic leader could coalesce them by inciting their passions, pointing out a common mission, and offering candy and t-shirts at meetings. Never doubt the power of free stuff to coalesce people!
Is coalescence reversible?
One is reversible: flocculation, the other is irreversible: coalescence. The reversible flocculation induced by excess surfactant is studied.
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 is a coalescing solvent?
A coalescent aid is a small amount of solvent contained in latex coatings. It is not a true solvent because it does not actually dissolve the latex resins. The coalescent aid helps the latex resins flow together, aiding in film formation.
Is texanol a solvent?
Texanol ester alcohol works well in a variety of other applications. It’s an ideal choice as a retarder solvent for use in coil coatings and high-bake enamels.
What does surfactant do in paint?
Most paints contain a variety of ingredients that may include pigments, surfactants, and binders. Surfactants are soap-like molecules that manufacturers add to paint to ensure proper performance. Paint surfactants help to separate and stabilize pigments, and they allow color additions to better blend with paint.
What is titanium dioxide used for in paint?
Titanium dioxide (TiO2) is the most important white pigment used in the coatings industry. It is widely used because it efficiently scatters visible light, thereby imparting whiteness, brightness and opacity when incorporated into a coating.
What is an example sentence for coalesce?
Examples of coalesce in a Sentence a group of young reformers who gradually coalesced into a political movement The ice masses coalesced into a glacier over time.
How are Coalescents used in environmentally friendly coatings?
Permanent, or nonvolatile, coalescents are being introduced as the new superstars in environmentally friendly coatings formulation. These materials interact similarly to their volatile counterparts, but rather than being released as toxins during the drying process, they remain permanently solvated within the final dry film.
What is the common denominator for permanent coalescent agents?
The common denominator for permanent coalescent agents used in low-VOC formulation is that there is no common denominator. The efficiency differences between coalescents Optifilm 400, Loxanol CA 5310, and Efka PL 5651 were significantly dependent on the system in which they were being investigated.
What are the different types of Coalescents in paint?
Common coalescents include ester alcohols, esters, and glycol ethers. Eastman Optifilm™ additive OT1200 uniquely improves the application properties of your paint through improved workability and longer open time over a range of application conditions.
Which is the best coalescent for latex coatings?
Eastman Optifilm™ enhancer 300 is a low odor, coalescent that is safe, efficient and nonyellowing. Used in a variety of latex types, it is also compatible with solvent borne resins, improving the rheology, flexibility, and adhesion of coatings based on these resins.
