1/2POctober 2019DISPARLON 6500
(Anti-Slumping agent)
DISPARLON 6500 is a strong thi.otropic agent based on amide wa. and recommended for non-solvent as well as
non-polar systems. Unlike hydrogenated castor wa. products, 6500 permits incorporation at higher temperaturesand functions as a strong anti-slumping agent without seeding.

ADVANTAGES● E.cellent cost/performance

100 % active and can produce a strong thi.otropic structure free from slumping.
● High production efficiency

Permits incorporation on high speed grinding equipments at higher temperature without causing
seeding, which is not allowed for hydrogenated castor wa. products. No overnight standing required.
● Thi.otropy with good heat resistance and stability on ageing.
6500 assures good shelf stability and does not cause seeding, nor loss of effect. 6500 is used in adhesives toprevent slumping due to high temperature.

APPLICATIONS
For sealant and adhesives
6500 is used in sealant such as Oil based, Urethane, Silicone and Thiokol etc. as anti-slumping agent and quite
effective at higher temperature during application and thereafter.
In Synthetic rubber, Epo.y, Acrylic/Cyanamide adhesives it prevents settling of e.tenders and prevents phaseseparation. When used in rubber adhesives for laminating decorative films to plywood panels, 6500 prevents thepenetration of the adhesive into wood substrate without reducing initial bonding strength at heat pressing.

INCORPORATION
6500 is usually added at pre-mi.ing and is swollen when the mi.ture is dispersed at activation temperature. This
product, unlike castor wa.es, permits incorporation on heat generating high speed grinding equipment and does
not require overnight standing for full rheology development.
Additive levels
For sealant and adhesives :0.6 ～ 2.0 % by weight on total formulation.

2/2PMethod● Use in non-polar solvent systems
6500 is designed to be dispersed on heat generating high speed grinding equipments to activate at 50～80℃.
Such equipment include Sand mill, Attritor, Dyno mill, high speed dissolver, etc. Activation temperature can varydepending on the solvent and resin used and their ratio. Prior tests are therefore required to ascertain optimum
dispersing temperature.
● Use in non-solvent systems

Again there could be some variation in dispersing temperature depending on the vehicle and its content.
70 ～100℃ is suggested for swelling and dispersing 6500 in non-solvent systems.

TYPICAL PROPERTIES
Appearance :Melting point :Fineness of dispersion :White to light yellow fine powder
Appro.. 123℃
Ma. .30μCAUTION
In paint and coatings.
6500 can sometimes cause poor recoatability or intercoat adhesion when this products is used in paint and coatings.
Therefore, thorough preliminary test is absolute.
