MSP-20 Sealer®

Technical data at 23 °C and 60 % RV

Paintability
MSP-20 Sealant can be painted with water based paints. Solvent based paints might delay the drying process. For unknown combinations of paint and sealant we recommend pretesting. In general, sealants are more elastic than paint systems. Therefore dried paint could crack as a result of joint movements.

Joint dimensions
Use PE- or PU foam backing rods to create the required joint depth. In case of insufficient joint depth use PE film as a bond breaker. For joint widths larger than 12 mm, joint depth should be 1/3 of the width + 6mm. Joint widths less than 12mm, use 6mm joint depth. Connection and expansion joints should fulfill national regulations.

Substrates
MSP-20 Sealant gives adhesion to substrates such as powder coated, varnished, galvanized, anodized and cromed metals. For many plastics (except PE, PP), wood and various types of stone and stone-like substrates. The compatibility with natural stone should be checked first. Due to the large variety of different plastics and composites, preliminary tests are recommended. Please consult our primer list in any case of doubt.

Processing
Apply with hand-, air- or battery gun. Tool the joint with soapy water and jointing tool. Surfaces should be clean, free of grease and dust. Remove loose parts. Application temperatures shouldn’t be below 5ºC. Rainy or misty weather conditions are unsuitable for sealant application. Remove stains with turpentine.

Chemical resistance

• Good against water, salt water, aliphatic solvents, oils, grease, diluted inorganic acids and alkalis.
• Moderate against esters, ketone and aromatics
• Not resistant against concentrated acids and chlorinated hydrocarbons

Colours
White, Dust-grey, Concrete-grey and Black. Other colors (off white, beige, rosa-beige, light-grey, plebble-grey) on request.

Packing
Foil packages of 600ml; boxes of 12 pieces. Other packaging forms available on request.

Shelf life
MSP-20® Sealant has a shelf life of at least 12 months if stored in unopened containers in cool (between +5ºC and +25ºC) and dry conditions.

Safety precautions
Beep uncured sealant out of reach of children. Avoid prolonged contact with uncured sealant. In case of contact with eyes, rinse with plenty of water and consult a doctor. For comprehensive safety instructions, see corresponding Material Safety Data Sheets (available on request).
