LT-1094 Aluminum Pigment

PRODUCT DESCRIPTION

LT-1094 is a fine particle size aluminum pigment produced in pellet form to reduce the potential for generating airborne pigment particles and to improve ease of handling. This is an economical grade and can be used to create a gray masstone metallic appearance with good opacity at low cost – however it is not recommended for color critical applications nor for use with chromatic pigments as it will not produce clean color effects. Although this grade is based on a leafing aluminum pigment, it will not exhibit leafing characteristics in most plastic applications. LT-1094 is suitable for use in both plastics and powder coating applications.

PRODUCT APPLICATION

LT-1094 is an economical aluminum pigment provided in pellet form for easy handling and incorporation. It is compatible with a variety of polymers, particularly polyolefins. It is typically used to make concentrates or compounds for use in final processing by injection molding, extrusion, blow molding, or blown film processes. Because of it’s high aluminum pigment concentration and highly compacted form, it is recommended for use in masterbatch or compounding processes where enough shear exists to completely disperse the aluminum pigment. It is not recommended for use directly in end-use processing.

Additionally, LT-1094 can be employed in co-extruded powder coating applications.

INCORPORATION GUIDELINES

Plastic Application – It is normally sufficient to tumble blend the pellets with the base resin and any additional colorants or additives before processing. Incorporation techniques should not subject the flakes to high shear forces.

Co-Extruded Powder Application – When using LT-1094 for manufacturing powder coatings, care must be taken to maintain the aesthetics of the flake and to allow for safe incorporation. The blending of the LT-1094 with the powder coating resins should be carried out in a low intensity mixer. If this cannot be accomplished, the LT-1094 pellets should be added at the very end of a high intensity mixer cycle. The objective of mixing is only to distribute the LT-1094 throughout the batch and not to reduce the pellets to fine particles. When discharging the batch from the mixer to the extruder, the vessels should be bonded to the same electrical potential to prevent static electricity build up. Single or twin-screw extruders can then be used to provide proper dispersion of the LT-1094 into the powder coating resin. The metallic blend should be extruded below the curing temperature of the resin and then micronized to the proper size. Excessive shear at any point in this process can cause flakes to become folded or broken, thus creating a large number of smaller flakes. This will result in a reduced reflectivity of the flakes and a graying in color.


SAFETY AND HANDLING

Aluminum pigment should be stored in the original shipping container and kept tightly sealed. Store containers in a cool, dry, well-ventilated, and properly rated area. Avoid any conditions that will suspend or float the particles in the air, creating a dust cloud. Avoid all possible sources of ignition. For additional information, please refer to the Safety Data Sheet (SDS) for this product, available from Silberline upon request. An SDS is supplied with all samples of this grade.
