CHT MM TA2 (RTV TA2) Thixotroping Additive

MM TA2 is a completely new, specially formulated thixotroping agent, for use with the MM900 series of high strength 2-part Silicone Moulding Rubbers.

It has been designed to produce an attractive butter-on consistency within seconds of addition to the catalysed or uncatalysed liquid rubber. It can be employed with the catalyst, MM CAT B 5NT where a long working period is required or, it can be used with MM CAT R5 NT for a fast cure system, which can be demoulded within 2 hours.

Features:

• Easy addition level
• Rapid development of thixotropy
• Suitable for vertical applications within minutes

Typical Properties:

Typical physical properties for MM900 Series are given in the corresponding technical data sheets. Because of the thixotropic nature of an MM900 / MM TA2 system it is almost impossible to produce flawless sheets of rubber for physical testing.

Experience has shown that the MM900 Series Rubbers / MM TA2 catalysed with MM CAT B5 NT shows little significant change in physical properties from the conventionally cured rubber. A slight drop in physical properties is encountered with the MM900/ MM CAT R 5NT / MM TA2 system but no more than that expected with fast curing systems.
