Arbomeric MP10

Application

Suitable for use in perimeter sealing in curtain walling and polyester powder coated frames, structural joints in brickwork and blockwork, and joints in lightweight cladding.

Description

A one part, low modulus, modified polymer sealant which cures, on exposure to moisture vapour, to form an elastic rubber.


Features and benefits:

  • Not recommended for floor joints.
  • Very good UV resistance.
  • Anticipated service life in excess of 20 years.
