Arma-Chek R Black Insulation Covering Mastic 290ml
[ACH-MASTICSD]

Arma-Chek R Black Insulation Covering Sealing Compound Mastic 290ml

Arma-Chek Mastic is a high quality sealant for use of Arma-Chek D and Arma-Chek R. Arma-Chek Mastic is designed for making elastic joints that require high strength.
Very good UV-resistance and ageing properties
Permanently elastic within temperatures from -40C to +120C
Neutral, odorless and fast curing
Paint compatible with most industrial paint or lacquer systems (both alkyd resin and dispersion based). Note: Due to the large scale of different types of industrial paints a paint compatibility test is recommended.

Usage	Arma-Chek Mastic can easily be extruded with a hand- or air-pressure gun at temperatures between 5°C and 35°C. In sealing applications Arma-Chek Mastic should be tooled or smoothed within 10 minutes (at 20°C / 50% R.H.) with a spatula or putty knife, occasionally moistened with a soap solution. Avoid soap solution penetrating between Arma-Chek overlap and sealant, which will result in loss of adhesion. In general the applied thickness of the mastic should be min. 3mm.
