Application

Alsan 770 TX is a variant that is more viscous/ thixotropic to reduce run‐off when applied to sloping and vertical surfaces. It is therefore used primarily for the waterproofing of details.

Description

A high‐performance, PMMA (polymethyl methacrylate) based waterproofing resin with low‐temperature flexibility. The resin is used in conjunction with reinforcement fleece, to create a seamless, durable and reliable waterproofing membrane. It can also be used to waterproof movement joints. Can be used with Alsan 070 catalyst.

Features and benefits:

  • Highly flexible and crack‐bridging even at extreme sub‐zero temperatures.
  • Permanently weather‐resistant.
  • UV, hydrolysis and alkali-resistant.
  • Fully bonded to the substrate, therefore no water ingress.
  • Easy and fast application via sheepskin roller or brush.
  • The most complex roof penetrations can be securely incorporated into the seamless waterproofing system.
  • Fast‐curing.
  • Can be applied to almost all substrates, including substrates of variable materials (in combination with the right Alsan PMMA primer).
  • Solvent‐free.

Applications:
