Arbomeric MP20
Verified by manufacturer 23 hours ago
A one part, high modulus, modified polymer sealant used in floor joints, heavy trafficked areas, prisons and secure units (supervised areas) forming anti-pick/anti-vandalism joints.
Application
Main Applications
Arbomeric MP20 is recommended for use in many forms of construction including: structural joints in heavy cladding, structural movement joints in floors and floor joints in heavily trafficked areas, prisons and secure units (supervised areas) forming anti-pick/anti-vandalism joints, or any area that could be subject to abuse and vandal attack. Arbomeric MP20 is over-paintable once fully cured.
(pre-use tests are advised to demonstrate compatibility with individual paints).
NB: Not recommended for joints in lightweight cladding and swimming pools.
Description
A one part, high modulus, modified polymer sealant which cures, on exposure to moisture vapour, to form a tough but elastic rubber.
Skin Time at 20ºC at 65% RH: 20-30 minutes
Application Temperature: + 5ºC to + 35ºC
Service Temperature: - 40ºC to + 120ºC
Chemical Resistance: Resistant to most dilute acids and alkalis. (Organic solvents may cause the sealant to swell and lose adhesion. Strong cleaning agents can cause surface deterioration and may affect the efficiency of the material).
UV Resistance: Very good
Service Life: 20 years + (when used in trafficked areas the life may be reduced)
Movement Accommodation: Butt joints (movement in tension and compression): 35%.
Lap joints (movement in shear): 70%
Colours: White, Grey, Black
