storage and transportation
separation or turbidity may occur during storage and transportation. mix well before use. warm to 30-60 °c and mix well.
special note
white spirit-based coating systems or those that are diluted with white spirit have a limited compatibility.
applications
ambient-curing plastic systems
special features and s
altri-sp-879s improves the dispersion of all conventional fillers, such as calcium carbonate and aluminum hydroxide. it reduces the viscosity of the filled resin, which enables increased filler content. in the majority of cases, the settling of the filler is significantly reduced during storage and when processing. altri-sp-879s is suited to stabilizing pigments in gel coats. the additive also contains a small quantity of a polysiloxane copolymer to reduce fl ooding and floating. this prevents the formation of bénard cells and improves the surface slip and leveling
recommended levels
0.5-1.5 % additive (as supplied) based upon the filler.
the above recommended levels can be used for orientation. optimal levels are determined through a series of laboratory tests.
coatings industry
special features and s
the additive provides a targeted, controlled fl occultation of the pigments. the system builds bridges between the individual pigment particles, thereby creating three-dimensional networks. this controlled
fl occultation of the pigments primarily prevents flooding/floating along with settling and sagging. altri-sp-880s is suited to stabilizing pigments in industrial coatings and architectural coatings. it increases gloss, prevents floating and reduces the mill base viscosity. the additive also contains a small quantity of a polysiloxane copolymer to reduce flooding and floating. this prevents the formation of bénard cells and improves the surface slip and leveling, and also the orientation of matting agents and aluminum pigments.
in the majority of cases, it is no longer necessary to add the silicone additives which are usually required.
recommended levels
amount of additive (as supplied) based upon pigment:
inorganic pigments:  3-10 %
titanium dioxides:       1-3 %
organic pigments:       8-16 %
the above recommended levels can be used for orientation. optimal levels are determined through a series of laboratory tests.
