BOSTIK PSR 40-01


 

DESCRIPTION

BOSTIK PSR 40-01 is a high elastic recovery sealant based on Polyurethane polymers (PU). Due to its good elasticity and low hardness, it is especially suitable for applications which are subject to large movements. BOSTIK PSR 40-01 exhibits non-sagging properties with excellent adhesion performance on a wide variety of substrates (except plastics) and can be overpainted with most water-based paints.

Polyurethane Special Range

APPLICATION
Sealing in general automotive and transportation constructions - e.g. bus, caravan, train and truck. - Sealing of air conditioning equipment. - Sealing of aluminium (airfreight) containers.
SMART BENEFITS
- Suitable for sealing applications - High elasticity - Cost effective
FEATURES
- High elongation and excellent elastic recovery - Low isocyanate (<0,1%). - Very good permanent elasticity. - Easy to apply. - Paintable with most water based paint. - Non-sagging properties.
ADHESION
The use of Prep CS is recommended for most typical substrates e.g. stainless steel, aluminium, 3CR12, ceramic glass and PVC floor covering. Surfaces should be clean, dry and free from dust and grease before the application of Prep CS. For other substrates please consult your Bostik representative for more Information. For details concerning the use of Prep CS please consult the TDS.
STORAGE STABILITY
BOSTIK PSR 40-01 can be stored for 12 months in an original, unopened container in vertical position and dry place at temperatures between +5°C and +25°C .
FURTHER INFORMATION
The following publication is available on request: Material Safety Data Sheets (MSDS) The information given and recommendations made herein are based on Bostik’s research only and are not guaranteed to be accurate. The performance of the product, its shelf life, and application characteristics will depend on many variables, including the kind of materials to which the product will be applied, the environment in which the product is stored or applied, and the equipment used for application. Any change in any of these variables can affect the product’s performance. It is the buyer’s obligation, prior to using the product, to test the suitability of the product for an intended use under the conditions that will exist at the time of the intended use.

METHOD OF USE
Simson ISR 70-03 sskf can easily be extruded with a hand- or air pressure gun at temperatures between +5°C and +35°C. In sealing applications, Simson ISR 70-03 sskf should be tooled or smoothened 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 joint sides and sealant, because this will create loss of adhesion. In bonding applications the substrates have to be assembled within 15 minutes (at 20°C/50% R.H.) after applying Simson ISR 70-03 sskf. In general an adhesive thickness of 2 mm is recommended. At a temperature of +20°C and a relative humidity of 50%, Simson ISR 70-03 sskf can be painted with the most industrial paints already 10 minutes after application. Best adhesion of paint coats is generally obtained if painted within 4 hours after applying Simson ISR 70-03 sskf. Cleaning tools or removing uncured residue of ISR 70-03 sskf can be done with a clean colourless cloth, wetted with Simson Liquid 1. It is recommended to make a trial first to check possible attack of the substrate by Liquid 1.
