Hardening and Wear-Resistant Agent

Overview:

A silicone surface additive for solvent-based, solvent-free, and aqueous systems. Suitable for coatings, inks, adhesives,

and room-temperature curing plastic systems, significantly reducing surface tension.

Typical Physical and Chemical Data

Chemical Composition: Polyether-modified polydimethylsiloxane.

Density

(20 °C):

1.04 g/ml

Recommended Dosage

0.05-0.3 % additive dosage (as supplied) based on the total formulation. For aqueous and UV systems, it can be added up to

1%

Applications

This additive is recommended for all solvent-based, solvent-free, and aqueous coatings, printing inks, and varnishes. It is particularly recommended

for improving the wettability of polyurethane, epoxy, and acrylate adhesives on substrates, as well as the substrate wetting capability of

epoxy-based room-temperature curing plastics.

Addition Method and Processing Guidance

This additive can be added at any stage of production, including post-addition. In room-temperature curing systems, to reduce the foam-stabilizing effect of the additive,

it is recommended to add it at the final stage of manufacturing.

Features and Benefits

Coatings and Printing Inks

This additive significantly reduces the surface tension of coatings and printing inks, thereby improving substrate wetting and preventing cratering. At the same

time, it also enhances surface slip and gloss. In aqueous systems, it can improve anti-blocking properties.

Adhesives and Sealants

It is a highly effective silicone surface additive. It can drastically reduce surface tension, thus enhancing the

surface wetting of the system on challenging substrates.

Room-Temperature Curing Systems

It is a highly effective silicone surface additive. It can drastically reduce surface tension, thus enhancing the

surface wetting of the system on challenging substrates.

Special Notes

Unlike conventional silicone oils, this additive is "user-safe." However, before use, a series of tests should be conducted to confirm

whether the additive stabilizes foam, and its recoatability and cratering tendency should also be evaluated.

Storage and Transportation

Separation or turbidity may occur at temperatures below 5

°C; heat to 20 °C and mix thoroughly.
