Silicone surfactant SiLP-2623

Description

SiLP-2623 is a silicone based surface surfactant for solvent-borne coatings systems. It slightly increase surface slip and slightly reduce the surface tension of coating systems. It exhibits good thermal stability and good leveling with defoaming properties.

Composition: Aralkyl-modified polymethylalkylsiloxane

Features

• Increase surface slip

• Good leveling and defoaming alibilty

• Good thermal stability

Application

SiLP-2623 is widely used as a leveling agent with a defoaming effect/doesn’t stabilize or only slightly stabilizesthe foam, depending on the polarity of the coating system. SiLP-2623 is thermally stable up to 250°C and doesn’t impact the intercoat adhesion.

In matte coatings, it is used to orientate the matting agent and in high-solid systems (polyurethane/acid-curing/unsaturated polyesters) that are difficult to matt, it provides optimal orientation of the matting agent without shining up. In flow coating, SiLP-2623 stabilizes the flow curtain and in metallic coatings it ensures consistent orientation of aluminum pigments.

How to use

SiLP-2623 is particularly recommended for all solvent-borne coatings.

Recommended use levels is 0.01-0.3% additive (as supplied) based upon total formulation.
