Thixotropic agent TM 100

Thixotropic agents such as TM 100 are additives which can be used, for example, to convert resins into a gel-like state. They have a large internal surface area (approx. 200 m²/g) and thus bind a lot of resin.
When stirred (subjected to shear forces), the thixotropic mixture is thinner than when at rest. The fumed silica thereby builds up a reversible, gel-like silica skeleton. This promotes easy distribution of the coating, either as a top coat in molds or as a finish in positive coatings.

In the TM 100 thixotropic agent, HD polyethylene fibrid fibers are included for ease of blending. In positive coatings (finishing coats on laminates applied by brush or roller), this forms a slightly textured surface.

• Yields thixotropic filling compouds and gelcoats
• Easy to disperse
• For epoxy, polyester, and vinyl ester resins

Compound: Amorphous silicic acid + HD polyethylene fibride

Colour: White
Density: approx. 1.55 g/cm³
Dry heat resistance: approx. 110 °C continuous
Melting temperature: approx. 132 °C
Apparent density: approx. 40 g/l

TM 100 is much easier to mix in than the standard thixotropic agent.

Addition:
0.5-5 % by weight, depending on the desired thixotropy and application thickness. However, these guide values are dependent on the viscosity of the resin and the ambient and substrate temperature. Preliminary tests to adjust the desired properties are required.

Storage:
Unopened at +5°C to +30°C and protected from moisture, draughts and UV radiation.

Thixotropic agents are highly hygroscopic (water-attracting) and must therefore be stored in a dry place. Only dry thixotropic agents may be used for thickening resins, otherwise, water will be carried into the resin/hardener mixture. This can lead to incorrect curing such as sticky or greasy surfaces.

Durability from date of delivery: 12 months

The volume details are intended to assist in judging the amount supplied. These details refer to the loose bulk amount. The contents may become compressed during transport or storage, and can, in conjunction with humidity, form agglomerates. Solid contents have to be ground or spread through a screen prior to their use.
